onChartFling never called in MPAndroidChart

Question

I have problem that onChartFling method is never called in my LineChart or BarChart. All other methods from OnChartGestureListener are called correctly, but these not. I put a breakpoint alo int BarLineChartTouchListener. Not called also.

Or is they any other way how to detect end of scrollin on fling ? onChartTranslate is called multiple times, is it possible to find out if onChartTranslate was called when fling stopped ?

Answer 1

The author says, the way to solve this is to modify the library:

"The reason therefore is, that I do not want to permanently recognize a fling-gesture or single tap when the chart is zoomed in and panned / dragged. Therefore, gestures do not work in zoomed mode. If you want to disable this, you will have to modify the library."

These lines should be modified:

if(mTouchMode == NONE) { // remove the if
    mGestureDetector.onTouchEvent(event);
}
