android - MPAndroidChart PieChart is not displayed when used inside ScrollView -

i want show piechart in fragment. following xml have written,

<scrollview         android:layout_width="match_parent"         android:layout_height="match_parent"         android:background="@color/background">          <linearlayout             android:id="@+id/graphcontainer"             android:layout_width="match_parent"             android:layout_height="match_parent"             android:orientation="vertical">              <com.github.mikephil.charting.charts.piechart                 android:id="@+id/piechart"                 android:layout_width="match_parent"                 android:layout_height="match_parent" />          </linearlayout>    </scrollview> 

the problem is, piechart not working if give match_parent or wrap_content. if give fixed height , width works fine. also, if remove scrollview , works charm! needs done in case of scrollview?

add below attribute in scroll view

android:fillviewport="true"
