当鼠标指针放在图形区域内时，实时图形停止。我需要一个实时图表，无论鼠标移动如何，都可以连续显示值。请帮帮我。
代码如下。请使用“jsfiddle.net”
HTML：
<script src="http://code.highcharts.com/highcharts.js"></script>
<script src="http://code.highcharts.com/modules/exporting.js"></script>
<div id="container" style="min-width: 310px; height: 400px; margin: 0 auto"></div>
JAVASCRIPT：
$(function () {

setInterval(function() {
var x1 = (new Date()).getTime(); // current time
var y1 = Math.random();
var x2 = (new Date()).getTime();

seriesa.addPoint([x1, y1], true, true);
seriesb.addPoint([x2, y2], true, true);
