Countdown to Ext JS 4: Drawing and Charting http://www.sencha.com/blog/ext-js-4-preview-drawing-and-charting Ext JS 4 does away with Flash for Charts, using fully accessible JavaScript instead. When we announced this new feature at SenchaCon, we almost brought the house down. Find out what our talented Charts team has been up to in Jamie Avin’s preview of Ext JS 4: Drawing and Charts. en-us jamie@extjs.com Copyright 2011 2011-02-09T21:04:09+00:00 Comment by Jack Chen It’s a great work. It’s a great work.

While using oppo charts is an option, there is a variance in the codebase that is tedious to debug to make a web and mobile (ipad) app have the same behavior.

But on iPad its rendering and response time is very slow. Also tap events are very slow in response. Any idea how we can improve performance of this so that animation will look smooth. Hi,

Fingers crossed you can get the zoom data range dragger implemented for the final release. Can I suggest a nice enhancement (if it’s not already on the drawing board) The ability to add a single dragger that can be used to zoom the data range on more than one chart. This would allow the end user to zoom/move several related charts from the one control. @Jamie, That’s great news.
