[英]How to add two Google charts on the one page?
我已将谷歌图表添加到页面的头部。 这将返回图表的图像。
我只需要在同一页面上添加第二个图表。
第二个图表的代码被忽略。 我很大程度上怀疑这是由于我错误地将每个图表的代码组合在一起。
第一张图表(行):
<!--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(馅饼):
<!--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在正文中调用每个图表:
<div id="chart_div"></div>
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和变量,但无济于事。
我现在有一个有效的解决方案。 它涉及辨别示例代码的哪些部分要复制以及什么不复制(如Oofpez所建议的)。 每个图表的数据,选项和图表变量都在ONE drawChart()函数中定义。
这是一个工作示例(只需复制并粘贴到HTML文档中):
...此示例进一步演示了如何组合不同的图表类型,即饼图和线条......

基本上你可以将函数drawChart
包装为参数传递,如:
function drawChart(chartType, containerID, dataArray, options)
和
call google.setOnLoadCallback(function() {
drawChart('barChart', 'div_id_1', test_array, null);
});
想要渲染图形的次数是多少:
var test_array = [
['Name', 'Count-A', 'Count-B'],
['Test-A', 4, 3],
['Test-B', 1, 2],
['Test-C', 3, 4],
['Test-D', 2, 0],
['Test-E', 2, 5]
];
google.load("visualization", "1", {packages: ["corechart",'table']});
google.setOnLoadCallback(function() {
drawChart('barChart', 'div_id_1', test_array, null);
});
google.setOnLoadCallback(function() {
drawChart('columnChart', 'div_id_2', test_array, null);
});
function drawChart(chartType, containerID, dataArray, options) {
var data = google.visualization.arrayToDataTable(dataArray);
var containerDiv = document.getElementById(containerID);
var chart = false;
if (chartType.toUpperCase() == 'BARCHART') {
chart = new google.visualization.BarChart(containerDiv);
}
else if (chartType.toUpperCase() == 'COLUMNCHART') {
chart = new google.visualization.ColumnChart(containerDiv);
}
else if (chartType.toUpperCase() == 'PIECHART') {
chart = new google.visualization.PieChart(containerDiv);
}
else if (chartType.toUpperCase() == 'TABLECHART')
{
chart = new google.visualization.Table(containerDiv);
}
if (chart == false) {
return false;
}
chart.draw(data, options);
}
基于@Dominor的答案,但是如果你从任意注册你的图表,只需构建一个在回调函数中执行的函数堆栈,如下所示:
google.setOnLoadCallback(drawChart);
// Callback that creates and populates a data table,
// instantiates the pie chart, passes in the data and
// draws it.
googleChartStack = [];
function drawChart() {
for (var i = googleChartStack.length - 1; i >= 0; i--) {
googleChartStack[i]();
}
}
然后,在模板中的其他位置,您可以推送到此堆栈。 在我的例子中,我正在迭代一些模板片段。
<script>
googleChartStack.push(function() {
var data = google.visualization.arrayToDataTable([
['A', 'B'],
['A', 1],
['B', 2]
]);
var options = {
title: 'none',
legend: 'none'
};
var chart = new google.visualization.PieChart(document.getElementById("relevant-id"));
chart.draw(data, options);
})
</script>
Google Charts的生产版本有一个时间错误,可防止在同一页面上加载多个图表。
谷歌在最新版本中对此进行了修复,该版本与冻结版本加载器一起提供: https : //developers.google.com/chart/interactive/docs/library_loading_enhancements#frozen-versions
相关主题: https : //groups.google.com/forum/?utm_medium = email&utm_source = footer#!msg / google- visualization-api/KulpuT418cg/ yZieM8buCQAJ
在上面的答案包中只添加了饼图...为了在同一页面上打印饼图和折线图,我们还必须包括行包:google.load('visualization','1.0',{'packages':['corechart', '线']});
完整代码: -
// Load the Visualization API and the piechart package.
google.load('visualization', '1.0', {'packages':['corechart','line']});
// 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]
]);
// Create the data table.
var data2 = new google.visualization.DataTable();
data2.addColumn('string', 'Topping');
data2.addColumn('number', 'Slices');
data2.addRows([
['Mushrooms', 3],
['Onions', 1],
['Olives', 15],
['Zucchini', 1],
['Pepperoni', 2]
]);
var data3 = new google.visualization.DataTable();
data3.addColumn('string', 'Year');
data3.addColumn('number', 'Sales');
data3.addColumn('number', 'Expenses');
data3.addRows([
['2004', 1000, 400],
['2005', 1170, 460],
['2006', 860, 580],
['2007', 1030, 540]
]);
// Set chart options
var options = {'title':'How Much Pizza I Ate Last Night',

chart.draw(data, options);
var chart2 = new google.visualization.PieChart(document.getElementById('chart_div2'));
chart2.draw(data2, options2);

也许当你指定
google.setOnLoadCallback(drawChart);
两次它第一次覆盖回调事件?
只是一个猜测......
你想要做的是为每个图表都有一个功能。 然后做
google.setOnLoadCallback(initialize);
并初始化调用每个函数来创建图表。 与在一个函数中绘制多个图表相比,它更加清晰。 它也有助于调试。
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("visualization", "1.1", {packages:["bar"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Day/Month', 'Sales', 'Goal'],
['Daily', 33549.17,47328.04],
['M-T-D', 96114.18,141984.12]
]);
var data1 = google.visualization.arrayToDataTable([
['Day/Month', 'Bookings', 'Goal'],
['Daily', 37991.21,47659.09],
['M-T-D', 95610.47,142977.27]
]);
var options = {
colors: ['#e0aa0e', '#ecbb6e','green'],
width: 800,
chart: {
title: 'Test Company Sales',
subtitle: 'Sales vs Goal',
}
};
var options1 = {
colors: ['#e0440e', '#ec8f6e','green'],
width: 800,
chart: {
title: 'Test Company Bookings',
subtitle: 'Bookings',
}
};
var chart = new google.charts.Bar(document.getElementById('sales'));
chart.draw(data, options);
var chart2 = new google.charts.Bar(document.getElementById('bookings'));
chart2.draw(data1, options1);
}
</script>
<div style="display: table; width: 100%;">
<div style="display: table-row">
<div id="sales" style="width: 900px; height: 500px; display: table-cell;"></div>
<div id="bookings" style="width: 900px; height: 500px; display: table-cell;"></div>
</div>
</div>
step_1。(将id curve_chart更改为其他名称(例如,ajay))
<body>
<div id="ajay" style="width: 900px; height: 500px"></div>
step_2。(在脚本元素中将此id分配给您的图表)..
var chart = new google.visualization.LineChart(document.getElementById('ajay'));
chart.draw(data, options);
}
