Highcharts：使用相同的div使用不同的系列数据多次加载图表
[英]Highcharts : using same div to load a chart multiple times with different series data
问题描述
I have written a function that creates a chart based on some graphdata as parameter and renders it to a div . 
我编写了一个函数，该函数基于一些graphdata作为参数创建图表并将其呈现给div。 Now I am reusing this function to generate same type of chart on same div to load different series data . 现在，我正在重用此函数在同一div上生成相同类型的图表，以加载不同的系列数据。 The problem is I can see the graph rendering shows previous charts labels for a second and then the new graph gets loaded with new labels . 问题是我可以看到图形渲染显示了先前的图表标签一秒钟，然后新图形被加载了新标签。 I dont want to see the old graph when my new graph gets loaded . 新图加载后，我不想看到旧图。 Please help . 请帮忙 。

Since you're using jQuery, have you tried simply emptying the container div as follows before redrawing the chart? 由于您使用的是jQuery，是否在重绘图表之前尝试按照以下方法清空容器div？
$('#container').html();
Perhaps this would be more beneficial since chart.destroy() doesn't seem to be working in your case. 也许这会更有益，因为chart.destroy()在您的情况下似乎不起作用。
From http://api.jquery.com/html/#html2 : 从http://api.jquery.com/html/#html2 ：
When .html() is used to set an element's content, any content that was in that element is completely replaced by the new content.
