On Touch-Event is invoked on all series if more then one point is next to the tap

I use the listener to make the tapped point bigger and display a snackbar.
Only the snackbar of the series added last to the graph is displayed.

Reason for this behaviour is the handling of onTouchEvent in Graphview:

    public boolean onTouchEvent(MotionEvent event) {
        boolean b = mViewport.onTouchEvent(event);
        boolean a = super.onTouchEvent(event);

        // is it a click?
        if (mTapDetector.onTouchEvent(event)) {
            for (Series s : mSeries) {
                s.onTap(event.getX(), event.getY());
            }
            if (mSecondScale != null) {
                for (Series s : mSecondScale.getSeries()) {
                    s.onTap(event.getX(), event.getY());
                }
            }
        }

if two points in two different series have a distance less then 120 to the tap both listeners will be called, because s.onTap(event.getX(), event.getY()); only knows the points of its own series and will call its listener if one point has a distance < 120.
I guess sometimes this may be the expected behaviour, but I dont know if this should be the default behaviour.
Whats your thoughts on this?
