推荐答案

我最近写了一篇关于在 Ext JS 4 中创建股票图表的博客文章 - http://www.scottlogic.co.uk/2011/12/ext-js-4-stock-charts/.它使用了几百分，在现代浏览器中表现良好，在 IE7-8 中也不错.

I've recently written a blog post on creating stock charts in Ext JS 4 - http://www.scottlogic.co.uk/2011/12/ext-js-4-stock-charts/. It uses a couple of hundred points and performs fine in modern browsers and isn't too bad in IE7-8.

然而，即使在搞乱了 Ext JS 构建系统之后，运行图表所需的最小 Ext 构建仍然是大约 0.5MB，这对于某些应用程序来说太重了.但是，CSS 可以简化为几条规则 - 如果您愿意花时间尝试从庞大的 ext-all.css 中找出您需要哪些规则！

This said however, even after messing with the Ext JS build system, the minimum Ext build required to run the charts is still something like .5MB which is too heavy weight for some applications. The CSS however can be chopped down to just a few rules - if you're willing to spend the time trying to figure out which ones you need out of the huge ext-all.css!
