what gwt graphics library shall be used for client side stock charting development?

I am just starting gwt development and would like to know what is t开发者_C百科he right way to create client side stock charting with gwt.

I've checked on highchart, which looks good but it is not gwt based.

gwt-graphics library seems the right one but not very active.

Google gwt-visualization seems not allow modification on top to support candlestick and other complicated requirements.

gchart seems not only support simple line charts and not extensible to candlestick easily.

Any suggestions ?

I don't know about any GWT specific charting libraries. However there are some GWT wrapper for existing Javascript Charting libraries:

• Dygraphs
• Protovis (Protovis-GWT)
• Raphael (Raphael-gwt)

I personally use google visualization and for simple charts (Barchart, etc) it is fine. I also like dygraphs because it has some neat features (zooming, stacking, etc). In the end you can always write your own GWT wrapper for an existing javascript charting library.
