我是谷歌图表可视化的新手。我使用“谷歌电子表格”作为我的图表的数据源,但是当我尝试添加过滤器类别时,我似乎无法控制并合并谷歌游戏中的两个示例
这就是我展示饼图的方式:
<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 query = new google.visualization.Query(
'http://spreadsheets.google.com/tq?key=0ArCLNmjk_GPpdHVZbVVuUlNKUF9TTHlpaWxPY1dmUnc&range=B1:C4&pub=1');
query.send(handleQueryResponse);
}
function handleQueryResponse(response) {
if (response.isError()) {
alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage());
return;
}
var data = response.getDataTable();
var chart = new google.visualization.PieChart(document.getElementById('columnchart'));
chart.draw(data, null);
}
</script>
<title>Data from a Spreadsheet</title>
</head>
<body>
<span id='columnchart'></span>
</body>
</html>
我在电子表格中的第一个范围(COLUMN A)有“类别”的定义,我想将过滤器添加到我的图表中。
答案 0 :(得分:3)
您需要解决以下几个问题:首先,您的查询仅限于电子表格中的两列(B1:C4
,均称为“计数”),但不包括控件。其次,图表的容器应该是div,而不是span。第三,为了使用控件,您需要为图表使用ChartWrapper,并且必须为API提供“controls”包。这是一个有效的代码示例:
[JavaScript的]
function drawChart() {
var query = new google.visualization.Query('http://spreadsheets.google.com/tq?key=0ArCLNmjk_GPpdHVZbVVuUlNKUF9TTHlpaWxPY1dmUnc&pub=1');
query.send(handleQueryResponse);
}
function handleQueryResponse(response) {
if (response.isError()) {
alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage());
return;
}
var data = response.getDataTable();
var control = new google.visualization.ControlWrapper({
containerId: 'control_div',
controlType: 'CategoryFilter',
options: {
filterColumnIndex: 0,
ui: {
}
}
});
var chart = new google.visualization.ChartWrapper({
containerId: 'chart_div',
chartType: 'PieChart',
options: {
height: 400,
width: 600
},
view: {
columns: [0, 1]
}
});
var dashboard = new google.visualization.Dashboard(document.querySelector('#dashboard'));
dashboard.bind([control], [chart]);
dashboard.draw(data);
}
google.load('visualization', '1', {packages:['controls'], callback: drawChart});
[HTML]
<div id="dashboard">
<div id="control_div"></div>
<div id="chart_div"></div>
</div>
