  i am trying to make vertical axis labeled in indian ١،٢،٣ and plotted in Indian too  , however it seems it has no meaning for computer , since there is no native encoding for arabic number , however in terms of english 0,1,2,3... you can do calculations no problem in that , the problem i must to show indian-arabic values
