android - how to group two barchat from mpandroidchart lib -


i want display in groups of 2 barcharts following barcharts:

mpandroidchart - multiples bar chart example

any feedback appreciate.

here code:

public class barchartactivitymultidataset extends demobase implements onseekbarchangelistener {  private barchart mchart; private seekbar mseekbarx, mseekbary; private textview tvx, tvy;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);

i updated following class barchartactivitymultidataset above code.
