how about the new Canvas API? may be too bleeding edge to be counted on but it is functional in Chrome and Firefox, and looks to have a lot of potential. Its API reminds of Quartz / OpenGL (but a lot simpler) which makes programatic drawing pretty easy.
新的 Canvas API 怎么样？可能太前沿而无法指望，但它在 Chrome 和 Firefox 中可以正常工作，并且看起来有很大的潜力。它的 API 让人想起 Quartz / OpenGL（但要简单得多），这使得编程绘图变得非常容易。

We were going through the same issue and ended up using JQPlot. It is extensive, JQuery based and so far so good.
我们遇到了同样的问题，最终使用了 JQPlot。它是广泛的，基于 JQuery，到目前为止还不错。
