我正在尝试制作一个包含 2 条线的谷歌折线图。
您应该能够通过两个复选框打开和关闭它们(显示/隐藏)..
谁有制作这个节目的想法，或者给点建议？
我猜是一些 onClick jQuery 的东西？
<html>
<head>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Year', 'Sales', 'Expenses'],
['2004', 1000, 400],
['2005', 1170, 460],
['2006', 660, 1120],
['2007', 1030, 540]
]);
var options = {
title: 'Company Performance'
};
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>
</body>
</html>
最佳答案
试试这个
标记:
<body>
<div id="chart_div" style="width: 900px; height: 500px;"></div>
<button type="button" id="hideSales" >Hide Sales</button>
<button type="button" id="hideExpenses" >Hide Expence</button>
</body>
脚本:
<script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Year', 'Sales', 'Expenses'],
['2004', 1000, 400],
['2005', 1170, 460],
['2006', 660, 1120],
['2007', 1030, 540]
]);
var options = {
title: 'Company Performance'
};
var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data, options);
var hideSal = document.getElementById("hideSales");
hideSal.onclick = function()
{
view = new google.visualization.DataView(data);
view.hideColumns([1]);
chart.draw(view, options);
}
var hideExp = document.getElementById("hideExpenses");
hideExp.onclick = function()
{
view = new google.visualization.DataView(data);
view.hideColumns([2]);
chart.draw(view, options);
}
}
