i don't know making mistake how recitify if banging head in wall hours can helpme out how resolve problem!

bar entries count , xaxis labels count should equal. adding 2 xaxis labels in getxaxisvalues() method. may getting more 2 bar entries in bardataset.

add xaxis labels equal bar entries count in bardataset.
