MPAndroidChart Line chart scrollview overlap

Question

I am facing a problem when adding a scrollview to my layout. When ever I change the orientation to landscape and scroll, the views seem to overlap

Following below is the code from the layout file. Can any one help me to figure out why the Details and the chart over lap???

<?xml version="1.0" encoding="utf-8"?>

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"

No need to use external scroll views

Comment 'computeScroll()' method or 'Utils.postInvalidateOnAnimation(mChart);' in the bellow path. This method may block your thread for 2, 3 minutes and this leads to delay, lagging, live value update issues , etc..

com/github/mikephil/charting/listener/BarLineChartTouchListener.java

Definitely this will resolve all scrolling issues like delay, hangs etc...
