I solve it like this: ``` chart.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { switch (event.getAction()) { case MotionEvent.ACTION_DOWN: { scrollView.requestDisallowInterceptTouchEvent(true); break; } case MotionEvent.ACTION_CANCEL: case MotionEvent.ACTION_UP:...

thanks
