Class AreaChartBuilder

AreaChartBuilder

Builder for area charts. For more details, see the Google Charts documentation.

Here is an example that shows how to build an area chart.

  // Create a data table with some sample data.
  var sampleData = Charts.newDataTable()
      .addColumn(Charts.ColumnType.STRING, "Month")
      .addColumn(Charts.ColumnType.NUMBER, "Dining")
      .addColumn(Charts.ColumnType.NUMBER, "Total")
      .addRow(["Jan", 60, 520])
      .addRow(["Feb", 50, 430])
      .addRow(["Mar", 53, 440])
      .addRow(["Apr", 70, 410])
      .addRow(["May", 80, 390])
      .addRow(["Jun", 60, 500])
      .addRow(["Jul", 100, 450])
      .addRow(["Aug", 140, 431])
      .addRow(["Sep", 75, 488])
      .addRow(["Oct", 70, 521])
      .addRow(["Nov", 58, 388])
      .addRow(["Dec", 63, 400])
      .build();

  var chart = Charts.newAreaChart()
      .setTitle('Yearly Spending')
      .setXAxisTitle('Month')
      .setYAxisTitle('Spending (USD)')
      .setDimensions(600, 500)
      .setStacked()
      .setColors(['red', 'green'])
      .setDataTable(sampleData)
      .build();

Detailed documentation

build()

Builds the chart.

Return

Chart — A Chart object, which can be embedded into documents, UI elements, or used as a static image.


reverseCategories()

Reverses the drawing of series in the domain axis. For vertical-range charts (such as line, area or column charts), this means the horizontal axis is drawn from right to left. For horizontal-range charts (such as bar charts), this means the vertical axis is drawn from top to bottom. For pie charts, this means the slices are drawn counterclockwise.

// Creates a pie chart builder and sets drawing of the slices in a counter-clockwise manner.
var builder = Charts.newPieChart();
builder.reverseCategories();

Return

AreaChartBuilder — This builder, useful for chaining.


setBackgroundColor(cssValue)

Sets the background color for the chart.

// Creates a line chart builder and sets the background color to gray
var builder = Charts.newLineChart();
builder.setBackgroundColor("gray");

Parameters

NameTypeDescription
cssValueStringThe CSS value for the color (such as "blue" or "#00f").

Return

AreaChartBuilder — This builder, useful for chaining.


setColors(cssValues)

Sets the colors for the lines in the chart.

// Creates a line chart builder and sets the first two lines to be drawn in green and red,
// respectively.
var builder = Charts.newLineChart();
builder.setColors(["green", "red"]);

Parameters

NameTypeDescription
cssValuesString[]An array of color CSS values, such as ["red", "#acf"]. The nth element in the array represents the color of the nth line in the chart.

Return

AreaChartBuilder — This builder, useful for chaining.
