有没有办法通过突出显示属性将图像添加到 ExtJS 图表中的条形中？
我想在 onMouseOver 的列/栏中添加一个图标，并且想知道突出显示是否已经支持该图标。文档说您可以将任何可用的 Sprite 添加到突出显示对象（ http://docs.sencha.com/ext-js/4-0/#/api/Ext.chart.series.Bar-cfg-highlight 然而即使在精灵定义 ( http://docs.sencha.com/ext-js /4-0/#/api/Ext.draw.Sprite ）除了将类型设置为图像之外，没有提及如何执行此操作，
任何想法将不胜感激
！
I want to add an icon in the column/bar onMouseOver and was wondering if highlight already supported that. The docs say you can add whatever Sprite has available to the highlight object ( http://docs.sencha.com/ext-js/4-0/#/api/Ext.chart.series.Bar-cfg-highlight however even in the Sprite definition ( http://docs.sencha.com/ext-js/4-0/#/api/Ext.draw.Sprite ) there's no mention of how to do this beyond setting the type to image.
Any ideas would be greatly appreciated.
Thanks!

从文档来看，似乎没有一种简单的方法可以做到这一点。 Sprite 类支持
addCls和removeCls方法，但您可以尝试为 sprite 元素设置 className，并查看具有该 className 的元素的背景图像是否有效。否则，条形图的精灵元素必须重新定义为更复杂的元素，将图像作为组件。将来，您应该在 Sencha 论坛 上发帖，因为您会得到更快的回复。
From the docs there doesn't seem to be an easy way of doing this. The Sprite class supports
addClsandremoveClsmethods though, you could try setting a className to the sprite element and see whether a background image for an element with that className works. Otherwise the sprite element for the bar chart would have to be redefined into something more complex that takes images as a component.In future, you should post over on the Sencha forums as you will get a quicker response.
