Ringkasan
Beberapa Google Chart, seperti Diagram Area, Garis, dan 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 rangkaian
tertentu.
Dalam diagram berikut, kami menetapkan warna setiap deret 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 tersaturasi), tetapi juga dapat ditentukan dengan nama dalam bahasa Inggris. Contoh
berikut mengilustrasikan hal ini dan juga menunjukkan cara mengontrol
warna dengan memperbaiki palet diagram menggunakan opsi colors,
bukan menetapkan warna untuk masing-masing deret. Satu perbedaan adalah jika Anda memperbaiki palet dan jumlah rangkaian lebih banyak daripada warna di palet, warna tersebut akan digunakan kembali: jika palet terdiri dari merah dan biru, setengah rangkaian 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']
};

<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 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']
};

[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 yang dapat dilakukan melalui opsi lineDashStyle, yang menggunakan array angka. Angka pertama menunjukkan panjang tanda pisah, dan angka kedua menunjukkan celah setelahnya. Jika ada angka ketiga,
itu adalah panjang garis putus-putus berikutnya, dan angka keempat, jika ada,
adalah panjang celah berikutnya.
Saat diagram digambar, panjang ini diulang, sehingga [4,
4] berarti urutan garis putus-putus 4 panjang dan celah 4 panjang. [5, 1, 3] berarti tanda pisah 5 panjang, celah 1 panjang, garis putus 3 panjang, celah 5 panjang, dan seterusnya. Beberapa contoh:
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'],
