We’re excited to share with you the beta release of Sencha Touch Charts. Touch Charts is a new add-on to Sencha Touch that we think will change how people interact with mobile web data. Just likeAJAX was a revolution because it accelerated work flow by eliminating page refreshes, Touch Charts allows users to explore and interact with data in-session without high latency server image serving. With the included gesture controls in Touch Charts, users can zoom in and out of data, pan across data sets, as well as quickly aggregate and filter data series.
