如何在一页上添加两个谷歌图表? [英] How to add two Google charts on the one page?
问题描述
我已将 Google 图表添加到页面的顶部.这将返回图表的图像.
I've added Google chart to the head of my page. This returns an image of a chart.
我只需要将第二个图表添加到同一页面.
I simply need to add a second chart to the same page.
第二个图表的代码被忽略.我在很大程度上怀疑这是由于我错误地组合了每个图表的代码.
The code for the second chart is ignored. I largely suspect this is due to me incorrectly combining the code for each chart.
第一张图表(折线):
<!--Load the AJAX API-->
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
// Load the Visualization API and the piechart package.
google.load('visualization', '1.0', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);
// Callback that creates and populates a data table,
// instantiates the pie chart, passes in the data and
// draws it.
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Month');
data.addColumn('number', 'Apples');
data.addColumn('number', 'Oranges');
data.addRows([
['Oct 11', 20, 0],
['Nov 11', 0, 0],
['Dec 12', 0, 20],
['Jan 12', 0, 10],
['Feb 12', 0, 10],
['March 12', 10, 10]
]);
// Set chart options
var options = {'width':960,
'height':300};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.LineChart(document.getElementById('line_chart'));
chart.draw(data, options);
}
</script>
第二张图表(饼图):
<!--Load the AJAX API-->
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
// Load the Visualization API and the piechart package.
google.load('visualization', '1.0', {'packages':['corechart']});
// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);
// Callback that creates and populates a data table,
// instantiates the pie chart, passes in the data and
// draws it.
function drawChart() {
// Create the data table.
var data = new google.visualization.DataTable();
data.addColumn('string', 'Topping');
data.addColumn('number', 'Slices');
data.addRows([
['Mushrooms', 3],
['Onions', 1],
['Olives', 1],
['Zucchini', 1],
['Pepperoni', 2]
]);
// Set chart options
var options = {'title':'How Much Pizza I Ate Last Night',
'width':400,
'height':300};
// Instantiate and draw our chart, passing in some options.
var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>
使用具有唯一 ID 的容器 div 在主体中调用每个图表:
Each of the charts are called in the body using a container div with a unique id:
<div id="chart_div"></div>
我的问题
我如何将这两个代码块拼接在一起?我试过复制 drawChart() 并指定唯一的函数名称和变量，但无济于事.
My question
How do I stitch these two blocks of code together? I've tried copying drawChart() and specifying unique function names and variables but to no avail.
推荐答案
解决方案
我现在有了一个可行的解决方案.它涉及辨别示例代码的哪些部分要复制，哪些部分不要复制(如 Oofpez 建议的那样).每个图表的数据、选项和图表变量都在 ONE drawChart() 函数中定义.
Solution
I now have a working solution. It involved discerning which parts of the example code to duplicate and what not to duplicate (as suggested by Oofpez). The data, options and chart variables for EACH of your charts are defined within the ONE drawChart() function.
这是一个工作示例(只需复制并粘贴到 HTML 文档中):
Here is a working example (just copy and paste into a HTML document):
