Thanks for your example. I download it and run it well.
But I download sencha touch 2.1.0-gpl from official site, and use sencha command to generate app to develop my app.
The structure is not the same with your example (2.0 ?). The touch-charts.js is replaced with many xxxChart.js.
Can you provide one simple example with 2.1.0? I tried many times but still not work
