Sencha Touch Chart: how can I handle TAP on a Bar column?

Question

I've successfully implemented a Bar chart; now I would like to trap the user touch. I've tried by using Interactions but cannot get the clicked item.

Answer 1

you have to create your own function in touch-charts-debug.js and refer that function in interactions instead of type:'iteminfo' in your chart.

I have tried with this option it works fine for me As am able to show drill down chart on tapping the bar.

Answer 2

The sencha-charts that I can find online say they use HTML5. If that is the case then you should be able to capture it like a mouse click except using touchstart, touchmove, touchend, and more.

Ah, just read. They also use jqtouch:

according to http://www.sencha.com/blog/introducing-sencha-touch-html5-framework-for-mobile/

Here are some examples for getting an event with jqtouch:
