Android: really cannot believe there's not a good and free chart library with touch event handling

i am searching for a free Chart Library for Android that can handle touch event on a item. All the free libraries that i've seen (achartengine, droidcharts and other) do not support it.

Can anyone help me开发者_开发技巧 in finding a native library (i know i can do in html5 but i would like to work in native java code) with touch enabled charts?

Thanks

AChartEngine offer support for :

• zoom (buttons and pinch)
• pan
• touch to get selected value

Is there any other interaction that you need?
