1. 引入所需的 js 库
-
在
<head></head>
中<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script type="text/javascript" src="https://www.google.com/jsapi?autoload={
'modules':[{
'name':'visualization',
'version':'1',
'packages':['corechart']
}]
}"></script>
2. 简单绘制 line
<html>
<body>
<div id="chart" style="width: 800px; height: 600px"></div>
<script type="text/javascript">
....
</script>
</body>
</html>
-
作用在某 div 元素上:
var chart = new google.visualization.LineChart($('chart')[0]);
-
表格选项:
var options = {
title: 'Temperature',
curveType: 'function',
animation: {
duration: 1000,
easing: 'in'
},
legend: {
position: 'bottom'
}
} -
存储二维数组的 DataTable
var data = google.visualization.arrayToDataTable([
['Time', 'Temperature'],
[new Date().toLocaleTimeString(), 0]
]); -
绘制:
chart.draw(data, options)
