JQPlot 只显示条形图但不画线

Question

我在使用 JQPlot 时遇到了问题，我设法在图表中显示了条形图，但由于某种原因没有绘制线条。

您可以在 JSFiddle 上看到代码（不适用于 Internet Explorer）： http://jsfiddle.net/gkp2N/

如果我将“seriesDefaults”更改为“series”，它会显示两条线，但不会绘制条形图。我花了两个小时才弄清楚这一点，希望有人能帮助我，谢谢！

这里是JS代码：

var s1 = [

不要忘记包含所需的插件（barRenderer）：

<script class="include" src=" http://www.jqplot.com/deploy/dist/plugins/jqplot.barRenderer.min.js"></script>
