Chart configuration options

Chart Types

Annotation chart configuration options

Name
colors

The colors to use for the chart elements. An array of strings, where each element is an HTML color string, for example: colors:['red','#004411'].

Type: Array of strings
Default: default colors
displayRangeSelector

Whether to show the zoom range selection area (the area at the bottom of the chart), where false means no.

The outline in the zoom selector is a log scale version of the first series in the chart, scaled to fit the height of the zoom selector.

Type: boolean
Default: true
displayZoomButtons

Whether to show the zoom buttons ("1d 5d 1m" and so on), where false means no.

Type: boolean
Default: true
max

The maximum value to show on the Y axis. If the maximum data point exceeds this value, this setting is ignored, and the chart is adjusted to show the next major tick mark above the maximum data point. This takes precedence over the Y axis maximum determined by scaleType.

This is similar to maxValue in core charts.

Type: number
Default: automatic
min

The minimum value to show on the Y axis. If the minimum data point is less than this value, this setting is ignored, and the chart is adjusted to show the next major tick mark below the minimum data point. This takes precedence over the Y axis minimum determined by scaleType.

This is similar to minValue in core charts.

Type: number
Default: automatic

Area chart configuration options

Name
areaOpacity

The default opacity of the colored area under an area chart series, where 0.0 is fully transparent and 1.0 is fully opaque. To specify opacity for an individual series, set the areaOpacity value in the series property.

{
  title: 'Hello',
  titleTextStyle: {
    color: '#FF0000'
  }
}
    
Type: object
Default: null

hAxis property that makes the horizontal axis a logarithmic scale (requires all values to be positive). Set to true for yes.

This option is only supported for a continuous axis.

Type: boolean
Default: false
hAxis.maxValue

Moves the max value of the horizontal axis to the specified value; this will be rightward in most charts. Ignored if this is set to a value smaller than the maximum x-value of the data. hAxis.viewWindow.max overrides this property.

Type: string
Default: A blend of the gridline and background colors
hAxis.minorGridlines.count

The minorGridlines.count option is mostly deprecated, except for disabling minor gridlines by setting the count to 0. The number of minor gridlines now depends entirely on the interval between major gridlines (see hAxis.gridlines.interval) and the minimum required space (see hAxis.minorGridlines.minSpacing).

Type: number
Default: 1
hAxis.minValue

Moves the min value of the horizontal axis to the specified value; this will be leftward in most charts. Ignored if this is set to a value greater than the minimum x-value of the data. hAxis.viewWindow.min overrides this property.

Type: number
Default: height of the containing element
interpolateNulls

Whether to guess the value of missing points. If true, it will guess the value of any missing data based on neighboring points. If false, it will leave a break in the line at the unknown point.

This is not supported by Area charts with the isStacked: true/'percent'/'relative'/'absolute' option.

Type: boolean
Default: false
isStacked

If set to true, stacks the elements for all series at each domain value. Note: In Column, Area, and SteppedArea charts, Google Charts reverses the order of legend items to better correspond with the stacking of the series elements (E.g. series 0 will be the bottom-most legend item). This does not apply to Bar Charts.

The isStacked option also supports 100% stacking, where the stacks of elements at each domain value are rescaled to add up to 100%.

The options for isStacked are:

  • false — elements will not stack. This is the default option.
  • true — stacks elements for all series at each domain value.
  • 'percent' — stacks elements for all series at each domain value and rescales them such that they add up to 100%, with each element's value calculated as a percentage of 100%.
  • 'relative' — stacks elements for all series at each domain value and rescales them such that they add up to 1, with each element's value calculated as a fraction of 1.
  • 'absolute' — functions the same as isStacked: true.

For 100% stacking, the calculated value for each element will appear in the tooltip after its actual value.

The target axis will default to tick values based on the relative 0-1 scale as fractions of 1 for 'relative', and 0-100% for 'percent' (Note: when using the 'percent' option, the axis/tick values are displayed as percentages, however the actual values are the relative 0-1 scale values. This is because the percentage axis ticks are the result of applying a format of "#.##%" to the relative 0-1 scale values. When using isStacked: 'percent', be sure to specify any ticks/gridlines using the relative 0-1 scale values). You can customize the gridlines/tick values and formatting using the appropriate hAxis/vAxis options.

100% stacking only supports data values of type number, and must have a baseline of zero.

Type: boolean/string
Default: false
legend

This option is only supported for a discrete major axis.

Type: boolean
Default: false
series

An array of objects, each describing the format of the corresponding series in the chart. To use default values for a series, specify an empty object {}. If a series or a value is not specified, the global value will be used. Each object supports the following properties:

  • annotations - An object to be applied to annotations for this series. This can be used to control, for instance, the textStyle for the series:

    series: {
      0: {
        annotations: {
          textStyle: {fontSize: 12, color: 'red' }
        }
      }
    }
              

    See the various annotations options for a more complete list of what can be customized.

  • areaOpacity - Overrides the global areaOpacity for this series.
  • color - The color to use for this series. Specify a valid HTML color string.
  • labelInLegend - The description of the series to appear in the chart legend.
  • lineDashStyle - Overrides the global lineDashStyle value for this series.
  • lineWidth - Overrides the global lineWidth value for this series.
  • pointShape - Overrides the global pointShape value for this series.
  • pointSize - Overrides the global pointSize value for this series.
  • pointsVisible - Overrides the global pointsVisible value for this series.
  • targetAxisIndex - Which axis to assign this series to, where 0 is the default axis, and 1 is the opposite axis. Default value is 0; set to 1 to define a chart where different series are rendered against different axes. At least one series must be allocated to the default axis. You can define a different scale for different axes.
  • visibleInLegend - A boolean value, where truemeans that the series should have a legend entry, and false means that it should not. Default is true.

You can specify either an array of objects, each of which applies to the series in the order given, or you can specify an object where each child has a numeric key indicating which series it applies to. For example, the following two declarations are identical, and declare the first series as black and absent from the legend, and the fourth as red and absent from the legend:

series: [
  {color: 'black', visibleInLegend: false}, {}, {},
  {color: 'red', visibleInLegend: false}
]
series: {
  0:{color: 'black', visibleInLegend: false},
  3:{color: 'red', visibleInLegend: false}

Type: boolean
useFirstColumnAsDomain

If set to true, the chart will treat the column as the domain.

Type: boolean
vAxes

Specifies properties for individual vertical axes, if the chart has multiple vertical axes. Each child object is a vAxis object, and can contain all the properties supported by vAxis. These property values override any global settings for the same property.

To specify a chart with multiple vertical axes, first define a new axis using series.targetAxisIndex, then configure the axis using vAxes. The following example assigns series 2 to the right axis and specifies a custom title and text style for it:

{
  series: {
    2: {
      targetAxisIndex:1
    }
  },

  • true — stacks elements for all series at each domain value.
  • 'percent' — stacks elements for all series at each domain value and rescales them such that they add up to 100%, with each element's value calculated as a percentage of 100%.
  • 'relative' — stacks elements for all series at each domain value and rescales them such that they add up to 1, with each element's value calculated as a fraction of 1.
  • 'absolute' — functions the same as isStacked: true.

For 100% stacking, the calculated value for each element will appear in the tooltip after its actual value.

The target axis will default to tick values based on the relative 0-1 scale as fractions of 1 for 'relative', and 0-100% for 'percent' (Note: when using the 'percent' option, the axis/tick values are displayed as percentages, however the actual values are the relative 0-1 scale values. This is because the percentage axis ticks are the result of applying a format of "#.##%" to the relative 0-1 scale values. When using isStacked: 'percent', be sure to specify any ticks/gridlines using the relative 0-1 scale values). You can customize the gridlines/tick values and formatting using the appropriate hAxis/vAxis options.

100% stacking only supports data values of type number, and must have a baseline of zero.

    series: {
      0: {
        annotations: {
          textStyle: {fontSize: 12, color: 'red' }
        }
      }
    }
              

    See the various annotations options for a more complete list of what can be customized.

  • color - The color to use for this series. Specify a valid HTML color string.
  • labelInLegend - The description of the series to appear in the chart legend.
  • targetAxisIndex - Which axis to assign this series to, where 0 is the default axis, and 1 is the opposite axis. Default value is 0; set to 1 to define a chart where different series are rendered against different axes. At least one series must be allocated to the default axis. You can define a different scale for different axes.
  • visibleInLegend - A boolean value, where true means that the series should have a legend entry, and false means that it should not. Default is true.

You can specify either an array of objects, each of which applies to the series in the order given, or you can specify an object where each child has a numeric key indicating which series it applies to. For example, the following two declarations are identical, and declare the first series as black and absent from the legend, and the fourth as red and absent from the legend:

vAxes

Specifies properties for individual vertical axes, if the chart has multiple vertical axes. Each child object is a vAxis object, and can contain all the properties supported by vAxis. These property values override any global settings for the same property.

To specify a chart with multiple vertical axes, first define a new axis using series.targetAxisIndex, then configure the axis using vAxes. The following example assigns series 2 to the right axis and specifies a custom title and text style for it:

Type: boolean
vAxes

Specifies properties for individual vertical axes, if the chart has multiple vertical axes. Each child object is a vAxis object, and can contain all the properties supported by vAxis. These property values override any global settings for the same property.

To specify a chart with multiple vertical axes, first define a new axis using series.targetAxisIndex, then configure the axis using vAxes. The following example assigns series 2 to the right axis and specifies a custom title and text style for it:

{
  series: {
    2: {
      targetAxisIndex:1
    }
  },
  vAxes: {
    1: {
      title:'Losses',

    }
  }
}
    

This property can be either an object or an array: the object is a collection of objects, each with a numeric label that specifies the axis that it defines--this is the format shown above; the array is an array of objects, one per axis. For example, the following array-style notation is identical to the vAxis object shown above:

vAxes: [
  {}, // Nothing specified for axis 0
  {
    title:'Losses',
    textStyle: {color: 'red'} // Axis 1

isStacked

If set to true, stacks the elements for all series at each domain value. Note: In Column, Area, and SteppedArea charts, Google Charts reverses the order of legend items to better correspond with the stacking of the series elements (E.g. series 0 will be the bottom-most legend item). This does not apply to Bar Charts.

The isStacked option also supports 100% stacking, where the stacks of elements at each domain value are rescaled to add up to 100%.

The options for isStacked are:

  • false — elements will not stack. This is the default option.
  • true — stacks elements for all series at each domain value.
  • 'percent' — stacks elements for all series at each domain value and rescales them such that they add up to 100%, with each element's value calculated as a percentage of 100%.
  • 'relative' — stacks elements for all series at each domain value and rescales them such that they add up to 1, with each element's value calculated as a fraction of 1.
  • 'absolute' — functions the same as isStacked: true.

For 100% stacking, the calculated value for each element will appear in the tooltip after its actual value.

The target axis will default to tick values based on the relative 0-1 scale as fractions of 1 for 'relative', and 0-100% for 'percent' (Note: when using the 'percent' option, the axis/tick values are displayed as percentages, however the actual values are the relative 0-1 scale values. This is because the percentage axis ticks are the result of applying a format of "#.##%" to the relative 0-1 scale values. When using isStacked: 'percent', be sure to specify any ticks/gridlines using the relative 0-1 scale values). You can customize the gridlines/tick values and formatting using the appropriate hAxis/vAxis options.

100% stacking only supports data values of type number, and must have a baseline of zero.

Type: boolean/string

    series: {
      0: {
        annotations: {
          textStyle: {fontSize: 12, color: 'red' }
        }
      }
    }
              

    See the various annotations options for a more complete list of what can be customized.

Type: boolean
vAxes

Specifies properties for individual vertical axes, if the chart has multiple vertical axes. Each child object is a vAxis object, and can contain all the properties supported by vAxis. These property values override any global settings for the same property.

To specify a chart with multiple vertical axes, first define a new axis using series.targetAxisIndex, then configure the axis using vAxes. The following example assigns series 2 to the right axis and specifies a custom title and text style for it:

{
  series: {
    2: {
      targetAxisIndex:1
    }
  },
  vAxes: {
    1: {
      title:'Losses',
      textStyle: {color: 'red'}
    }
  }
}
    

This property can be either an object or an array: the object is a collection of objects, each with a numeric label that specifies the axis that it defines--this is the format shown above; the array is an array of objects, one per axis. For example, the following array-style notation is identical to the vAxis object shown above:

vAxes: [
  {}, // Nothing specified for axis 0
  {
    title:'Losses',
    textStyle: {color: 'red'} // Axis 1
  }
]

interpolateNulls

Whether to guess the value of missing points. If true, it will guess the value of any missing data based on neighboring points. If false, it will leave a break in the line at the unknown point.

This is not supported by Area charts with the isStacked: true/'percent'/'relative'/'absolute' option.

Type: boolean
Default: false
isStacked

If set to true, stacks the elements for all series at each domain value. Note: In Column, Area, and SteppedArea charts, Google Charts reverses the order of legend items to better correspond with the stacking of the series elements (E.g. series 0 will be the bottom-most legend item). This does not apply to Bar Charts.

The isStacked option also supports 100% stacking, where the stacks of elements at each domain value are rescaled to add up to 100%.

The options for isStacked are:

  • false — elements will not stack. This is the default option.
  • true — stacks elements for all series at each domain value.
  • 'percent' — stacks elements for all series at each domain value and rescales them such that they add up to 100%, with each element's value calculated as a percentage of 100%.
  • 'relative' — stacks elements for all series at each domain value and rescales them such that they add up to 1, with each element's value calculated as a fraction of 1.
  • 'absolute' — functions the same as isStacked: true.

For 100% stacking, the calculated value for each element will appear in the tooltip after its actual value.

The target axis will default to tick values based on the relative 0-1 scale as fractions of 1 for 'relative', and 0-100% for 'percent' (Note: when using the 'percent' option, the axis/tick values are displayed as percentages, however the actual values are the relative 0-1 scale values. This is because the percentage axis ticks are the result of applying a format of "#.##%" to the relative 0-1 scale values. When using isStacked: 'percent', be sure to specify any ticks/gridlines using the relative 0-1 scale values). You can customize the gridlines/tick values and formatting using the appropriate hAxis/vAxis options.

100% stacking only supports data values of type number, and must have a baseline of zero.

Type: boolean/string
Default: false

  • annotations - An object to be applied to annotations for this series. This can be used to control, for instance, the textStyle for the series:

    series: {
      0: {
        annotations: {

  • targetAxisIndex - Which axis to assign this series to, where 0 is the default axis, and 1 is the opposite axis. Default value is 0; set to 1 to define a chart where different series are rendered against different axes. At least one series must be allocated to the default axis. You can define a different scale for different axes.
  • type - The type of marker for this series. Valid values are 'line', 'area', 'bars', 'candlesticks' and 'steppedArea'. Note that bars are actually vertical bars (columns). The default value is specified by the chart's seriesType option.

You can specify either an array of objects, each of which applies to the series in the order given, or you can specify an object where each child has a numeric key indicating which series it applies to. For example, the following two declarations are identical, and declare the first series as black and absent from the legend, and the fourth as red and absent from the legend:

series: [
  {color: 'black', visibleInLegend: false}, {}, {},
  {color: 'red', visibleInLegend: false}
]

interpolateNulls

Whether to guess the value of missing points. If true, it will guess the value of any missing data based on neighboring points. If false, it will leave a break in the line at the unknown point.

This is not supported by Area charts with the isStacked: true/'percent'/'relative'/'absolute' option.

Type: boolean
Default: false
isStacked

If set to true, stacks the elements for all series at each domain value. Note: In Column, Area, and SteppedArea charts, Google Charts reverses the order of legend items to better correspond with the stacking of the series elements (E.g. series 0 will be the bottom-most legend item). This does not apply to Bar Charts.

The isStacked option also supports 100% stacking, where the stacks of elements at each domain value are rescaled to add up to 100%.

The options for isStacked are:

  • false — elements will not stack. This is the default option.
  • true — stacks elements for all series at each domain value.
  • 'percent' — stacks elements for all series at each domain value and rescales them such that they add up to 100%, with each element's value calculated as a percentage of 100%.
  • 'relative' — stacks elements for all series at each domain value and rescales them such that they add up to 1, with each element's value calculated as a fraction of 1.
  • 'absolute' — functions the same as isStacked: true.

For 100% stacking, the calculated value for each element will appear in the tooltip after its actual value.

The target axis will default to tick values based on the relative 0-1 scale as fractions of 1 for 'relative', and 0-100% for 'percent' (Note: when using the 'percent' option, the axis/tick values are displayed as percentages, however the actual values are the relative 0-1 scale values. This is because the percentage axis ticks are the result of applying a format of "#.##%" to the relative 0-1 scale values. When using isStacked: 'percent', be sure to specify any ticks/gridlines using the relative 0-1 scale values). You can customize the gridlines/tick values and formatting using the appropriate hAxis/vAxis options.

100% stacking only supports data values of type number, and must have a baseline of zero.

Type: boolean/string
Default: false

This option is only supported for a discrete major axis.

Type: boolean
Default: false
series

An array of objects, each describing the format of the corresponding series in the chart. To use default values for a series, specify an empty object {}. If a series or a value is not specified, the global value will be used. Each object supports the following properties:

  • color - The color to use for this series. Specify a valid HTML color string.
  • labelInLegend - The description of the series to appear in the chart legend.
  • targetAxisIndex - Which axis to assign this series to, where 0 is the default axis, and 1 is the opposite axis. Default value is 0; set to 1 to define a chart where different series are rendered against different axes. At least one series must be allocated to the default axis. You can define a different scale for different axes.
  • visibleInLegend - A boolean value, where true means that the series should have a legend entry, and false means that it should not. Default is true.

You can specify either an array of objects, each of which applies to the series in the order given, or you can specify an object where each child has a numeric key indicating which series it applies to. For example, the following two declarations are identical, and declare the first series as black and absent from the legend, and the fourth as red and absent from the legend:

series: [
  {color: 'black', visibleInLegend: false}, {}, {},
  {color: 'red', visibleInLegend: false}
]
series: {

Type: boolean
vAxes

Specifies properties for individual vertical axes, if the chart has multiple vertical axes. Each child object is a vAxis object, and can contain all the properties supported by vAxis. These property values override any global settings for the same property.

To specify a chart with multiple vertical axes, first define a new axis using series.targetAxisIndex, then configure the axis using vAxes. The following example assigns series 2 to the right axis and specifies a custom title and text style for it:

{
  series: {
    2: {
      targetAxisIndex:1
    }
  },
  vAxes: {
    1: {
      title:'Losses',
      textStyle: {color: 'red'}
    }
  }
}
    

This property can be either an object or an array: the object is a collection of objects, each with a numeric label that specifies the axis that it defines--this is the format shown above; the array is an array of objects, one per axis. For example, the following array-style notation is identical to the vAxis object shown above:

vAxes: [
  {}, // Nothing specified for axis 0
  {
    title:'Losses',
    textStyle: {color: 'red'} // Axis 1
  }
]

    See the various annotations options for a more complete list of what can be customized.

  • type - The type of marker for this series. Valid values are 'line', 'area', 'bars', 'candlesticks' and 'steppedArea'. Note that bars are actually vertical bars (columns). The default value is specified by the chart's seriesType option.
  • color - The color to use for this series. Specify a valid HTML color string.

  • lineWidth - Overrides the global lineWidth value for this series.
  • pointShape - Overrides the global pointShape value for this series.
  • pointSize - Overrides the global pointSize value for this series.
  • pointsVisible - Overrides the global pointsVisible value for this series.
  • targetAxisIndex - Which axis to assign this series to, where 0 is the default axis, and 1 is the opposite axis. Default value is 0; set to 1 to define a chart where different series are rendered against different axes. At least one series must be allocated to the default axis. You can define a different scale for different axes.
  • visibleInLegend - A boolean value, where true means that the series should have a legend entry, and false means that it should not. Default is true.

You can specify either an array of objects, each of which applies to the series in the order given, or you can specify an object where each child has a numeric key indicating which series it applies to. For example, the following two declarations are identical, and declare the first series as black and absent from the legend, and the fourth as red and absent from the legend:

series: [
  {color: 'black', visibleInLegend: false}, {}, {},
  {color: 'red', visibleInLegend: false}
]
series: {

Displays trendlines on the charts that support them. By default, linear trendlines are used, but this can be customized with the trendlines.n.type option.

Trendlines are specified on a per-series basis, so most of the time your options will look like this:

var options = {
  trendlines: {
    0: {
      type: 'linear',
      color: 'green',
      lineWidth: 3,
      opacity: 0.3,
      visibleInLegend: true

vAxes

Specifies properties for individual vertical axes, if the chart has multiple vertical axes. Each child object is a vAxis object, and can contain all the properties supported by vAxis. These property values override any global settings for the same property.

To specify a chart with multiple vertical axes, first define a new axis using series.targetAxisIndex, then configure the axis using vAxes. The following example assigns series 2 to the right axis and specifies a custom title and text style for it:

{
  series: {
    2: {
      targetAxisIndex:1
    }
  },
  vAxes: {
    1: {
      title:'Losses',
      textStyle: {color: 'red'}
    }
  }
}
    

This property can be either an object or an array: the object is a collection of objects, each with a numeric label that specifies the axis that it defines--this is the format shown above; the array is an array of objects, one per axis. For example, the following array-style notation is identical to the vAxis object shown above:

vAxes: [
  {}, // Nothing specified for axis 0
  {
    title:'Losses',
    textStyle: {color: 'red'} // Axis 1
  }
]

To specify a chart with multiple vertical axes, first define a new axis using series.targetAxisIndex, then configure the axis using vAxes. The following example assigns series 2 to the right axis and specifies a custom title and text style for it:

{
  series: {
    2: {
      targetAxisIndex:1
    }
  },
  vAxes: {
    1: {
      title:'Losses',
      textStyle: {color: 'red'}
    }
  }
}
    

This property can be either an object or an array: the object is a collection of objects, each with a numeric label that specifies the axis that it defines--this is the format shown above; the array is an array of objects, one per axis. For example, the following array-style notation is identical to the vAxis object shown above:

vAxes: [
  {}, // Nothing specified for axis 0
  {
    title:'Losses',
    textStyle: {color: 'red'} // Axis 1
  }
]
    
Type: Array of object, or object with child objects
Default: null

isStacked

If set to true, stacks the elements for all series at each domain value. Note: In Column, Area, and SteppedArea charts, Google Charts reverses the order of legend items to better correspond with the stacking of the series elements (E.g. series 0 will be the bottom-most legend item). This does not apply to Bar Charts.

The isStacked option also supports 100% stacking, where the stacks of elements at each domain value are rescaled to add up to 100%.

The options for isStacked are:

  • false — elements will not stack. This is the default option.
  • true — stacks elements for all series at each domain value.
  • 'percent' — stacks elements for all series at each domain value and rescales them such that they add up to 100%, with each element's value calculated as a percentage of 100%.
  • 'relative' — stacks elements for all series at each domain value and rescales them such that they add up to 1, with each element's value calculated as a fraction of 1.
  • 'absolute' — functions the same as isStacked: true.

For 100% stacking, the calculated value for each element will appear in the tooltip after its actual value.

The target axis will default to tick values based on the relative 0-1 scale as fractions of 1 for 'relative', and 0-100% for 'percent' (Note: when using the 'percent' option, the axis/tick values are displayed as percentages, however the actual values are the relative 0-1 scale values. This is because the percentage axis ticks are the result of applying a format of "#.##%" to the relative 0-1 scale values. When using isStacked: 'percent', be sure to specify any ticks/gridlines using the relative 0-1 scale values). You can customize the gridlines/tick values and formatting using the appropriate hAxis/vAxis options.

100% stacking only supports data values of type number, and must have a baseline of zero.

Type: boolean/ string
Default: false
legend

  • 'in' - Inside the chart, by the top left corner.
  • 'none' - No legend is displayed.
  • 'right' - To the right of the chart. Incompatible with the vAxes option.
  • 'top' - Above the chart.

This option is only supported for a discrete major axis.

Type: boolean
Default: false
series

An array of objects, each describing the format of the corresponding series in the chart. To use default values for a series, specify an empty object {}. If a series or a value is not specified, the global value will be used. Each object supports the following properties:

  • areaOpacity - Overrides the global areaOpacity for this series.
  • color - The color to use for this series. Specify a valid HTML color string.
  • type - The type of marker for this series. Valid values are 'line', 'area', 'bars', 'candlesticks' and 'steppedArea'. Note that bars are actually vertical bars (columns). The default value is specified by the chart's seriesType option.
  • labelInLegend - The description of the series to appear in the chart legend.
  • lineDashStyle - Overrides the global lineDashStyle value for this series.
  • targetAxisIndex - Which axis to assign this series to, where 0 is the default axis, and 1 is the opposite axis. Default value is 0; set to 1 to define a chart where different series are rendered against different axes. At least one series must be allocated to the default axis. You can define a different scale for different axes.
  • visibleInLegend - A boolean value, where true means that the series should have a legend entry, and false means that it should not. Default is true.

You can specify either an array of objects, each of which applies to the series in the order given, or you can specify an object where each child has a numeric key indicating which series it applies to.For example, the following two declarations are identical, and declare the first series as black and absent from the legend, and the fourth as red and absent from the legend:

series: [
  {color: 'black', visibleInLegend: false}, {}, {},
  {color: 'red', visibleInLegend: false}
]
series: {
  0:{color: 'black', visibleInLegend: false},

vAxes

Specifies properties for individual vertical axes, if the chart has multiple vertical axes. Each child object is a vAxis object, and can contain all the properties supported by vAxis. These property values override any global settings for the same property.

To specify a chart with multiple vertical axes, first define a new axis using series.targetAxisIndex, then configure the axis using vAxes. The following example assigns series 2 to the right axis and specifies a custom title and text style for it:
