将数据插入jquery highcharts失败

标签: javascript html highcharts override pie-chart

我想将表中的数据放入highcharts饼图中。

首先加载表格,然后在关闭之前在底部加载,我会将数据导入高级图表进行显示。

我试过了,但只是没有工作,我认为语法错误...

<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"></script>

<table class="dataTbl">
<tbody>
<tr><td>fruit</td><td>qty</td></tr>
<tr><td>apple</td><td>1</td></tr>
<tr><td>banana</td><td>5</td></tr>
<tr><td>durian</td><td>3</td></tr>
</tbody>
</table>

//to load pie chart at the last, data obtain from table

<div id="container" style="width: 400px; height: 300px; margin: 0 auto"></div>


<script type="text/javascript">


var chart;

$(document).ready(function() {


        chart = new Highcharts.Chart({
                chart: {
                        renderTo: 'container',

                //chart.series[0].data.push([charttextvalue, chartnumbervalue]);

                //i want to push the data into series: data: but fail...

我提出了一个解决方案并将其放在jsfiddle:http://jsfiddle.net/CAKQH/21189/

因此,您必须要了解的主要事实是,实际图表的系列“部分”是一个可以采用几种不同形式的对象数组。您可以在此处详细了解:http://www.highcharts.com/ref/#series

因此,我的方法和您在代码中描述的方法的最大区别在于,我在实际创建图表之前继续为高级图表准备数据。

var piechartinfo = {
                            type: 'pie',
                            name: 'Custom Info',
                            data: []
                    }

我将数据数组留空,因为你的jquery循环会在之后填充它。

            //chart.series[0].data.push([charttextvalue, chartnumbervalue]);

            piechartinfo.data.push([charttextvalue, chartnumbervalue]);

然后,当实例化实际图表时,我添加了piechartinfo对象

series: [piechartinfo]
