【问题描述】:
我正在尝试将 google 提供的示例图表居中:https://google-developers.appspot.com/chart/interactive/docs/quick_start
我使用了我知道的基本 css 居中 (margin-right: auto;margin-left: auto;),但似乎没有任何效果。到目前为止,我只使用文本和图像,因此非常感谢任何帮助。
这是我正在使用的基本代码(包括谷歌图表 javascript)
<!DOCTYPE html> <html> <head> <style>
div.chart_div {
margin-left: auto;
margin-right: auto;
width: 800px; }
</style>
<!--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>
</head> <body>
<!--Div that will hold the pie chart-->
<div id="chart_div"></div>
</body> </html>
