Ringkasan
Beberapa Google Chart, seperti Area, Garis, dan Diagram Kombo, memiliki garis yang menghubungkan titik data. Anda dapat menyesuaikan warna, ketebalan, dan garis putus-putus menggunakan teknik di halaman ini.
Mengubah Warna
Anda dapat mengubah warna garis yang menghubungkan titik data di Google Chart dengan dua cara yang sedikit berbeda: dengan opsi colors untuk mengubah palet diagram, atau dengan opsi series untuk menentukan warna bagi rangkaian tertentu.
Dalam diagram berikut, kita menetapkan warna setiap rangkaian secara eksplisit.
var options = {
legend: 'none',
series: {
0: { color: '#e2431e' },
1: { color: '#e7711b' },
2: { color: '#f1ca3a' },
3: { color: '#6f9654' },
4: { color: '#1c91c0' },
5: { color: '#43459d' },
}
};

<script type="text/javascript">
google.charts.load("current", {packages:["corechart"]});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable
([['X', '1', '2', '3', '4', '5', '6'],
[1, 2, 3, 4, 5, 6, 7],
[2, 3, 4, 5, 6, 7, 8],
[3, 4, 5, 6, 7, 8, 9],
[4, 5, 6, 7, 8, 9, 10],
[5, 6, 7, 8, 9, 10, 11],
[6, 7, 8, 9, 10, 11, 12]
]);
var options = {
legend: 'none',
series: {
0: { color: '#e2431e' },
1: { color: '#e7711b' },
2: { color: '#f1ca3a' },
3: { color: '#6f9654' },
4: { color: '#1c91c0' },
5: { color: '#43459d' },
}
};
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data, options);
}

Di atas, warna ditentukan oleh nilai heksadesimal
(misalnya, '#e2431e', atau '#f00' untuk warna merah jenuh) tetapi juga dapat ditentukan dengan nama dalam bahasa Inggris. Contoh berikut menggambarkan hal ini, dan juga menunjukkan cara mengontrol warna dengan memperbaiki palet diagram dengan opsi colors, bukan menetapkan warna masing-masing rangkaian. Satu perbedaannya adalah jika Anda memperbaiki palet dan ada lebih banyak seri daripada warna dalam palet, warna tersebut akan digunakan kembali: jika palet Anda terdiri dari merah dan biru, setengah seri akan berwarna merah dan setengah lainnya. biru.
var options = {
legend: 'none',
colors: ['black', 'blue', 'red', 'green', 'yellow', 'gray']
};

Mengubah Ketebalan
Anda dapat mengontrol ketebalan garis dengan opsi lineWidth:
var options = {
legend: 'none',
hAxis: { maxValue: 7 },
vAxis: { maxValue: 13 },
lineWidth: 10,
colors: ['#e2431e', '#d3362d', '#e7711b',
'#e49307', '#e49307', '#b9c246']
};

<head>
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<script type="text/javascript">
google.charts.load("current", {packages:["corechart"]});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable
([['X', '1', '2', '3', '4', '5', '6'],
[1, 2, 3, 4, 5, 6, 7],
[2, 3, 4, 5, 6, 7, 8],
[3, 4, 5, 6, 7, 8, 9],
[4, 5, 6, 7, 8, 9, 10],
[5, 6, 7, 8, 9, 10, 11],
[6, 7, 8, 9, 10, 11, 12]
]);
var options = {
legend: 'none',
hAxis: { maxValue: 7 },
vAxis: { maxValue: 13 },
lineWidth: 10,
colors: ['#e2431e', '#d3362d', '#e7711b',
'#e49307', '#e49307', '#b9c246']
};
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>
</head>
<body>
<div id="chart_div" style="width: 900px; height: 500px;"></div>

Untuk mengontrol lebar garis pada suatu rangkaian, gunakan opsi series:
var options = {
legend: 'none',
hAxis: { maxValue: 7 },
vAxis: { maxValue: 13 },
series: {
0: { lineWidth: 1 },
1: { lineWidth: 2 },
2: { lineWidth: 4 },
3: { lineWidth: 8 },
4: { lineWidth: 16 },
5: { lineWidth: 24 }
},
colors: ['#e2431e', '#d3362d', '#e7711b',
'#e49307', '#e49307', '#b9c246']
};

[4, 5, 6, 7, 8, 9, 10],
[5, 6, 7, 8, 9, 10, 11],
[6, 7, 8, 9, 10, 11, 12]
]);
var options = {

'#e49307', '#e49307', '#b9c246']

Garis Putus-Putus
Banyak gaya garis putus-putus dimungkinkan melalui opsi lineDashStyle, yang menggunakan array angka. Angka pertama menunjukkan panjang tanda hubung, dan angka kedua menunjukkan celah di belakangnya. Jika ada angka ketiga, itu adalah panjang tanda hubung berikutnya, dan angka keempat, jika ada, adalah panjang celah berikutnya.
Saat diagram digambar, panjang ini diulang, sehingga [4,
4] berarti urutan tanda hubung 4 panjang dan celah
4 panjang. [5, 1, 3] berarti tanda hubung 5 panjang, celah 1 panjang, tanda hubung 3 panjang, celah 5 panjang, dan seterusnya. Beberapa contohnya:
var options = {
hAxis: { maxValue: 10 },
vAxis: { maxValue: 18 },
chartArea: { width: 380 },
lineWidth: 4,
series: {
0: { lineDashStyle: [1, 1] },
1: { lineDashStyle: [2, 2] },
2: { lineDashStyle: [4, 4] },
3: { lineDashStyle: [5, 1, 3] },
4: { lineDashStyle: [4, 1] },
5: { lineDashStyle: [10, 2] },
6: { lineDashStyle: [14, 2, 7, 2] },
7: { lineDashStyle: [14, 2, 2, 7] },
8: { lineDashStyle: [2, 2, 20, 2, 20, 2] }
},
colors: ['#e2431e', '#f1ca3a', '#6f9654', '#1c91c0',
'#4374e0', '#5c3292', '#572a1a', '#999999', '#1a1a1a'],
