At EdgeUX we love financial charting. The charting capabilities within ExtJS are good but need extending to get the most out of them.
This morning we have posted a demo of one of our financial charts on our website. It demonstrates a Candlestick chart which we wrote completely from scratch using ExtJS charting as a base.
It is 100% native ExtJS so integrates perfectly with ExtJS stores and you can use it exactly as you would any other ExtJS chart. The documentation for the Candlestick can be found here.
The use of our charting extensions including this one have a commercial license so if you are interested in using them please purchase them or contact us via our website.
