I am sorry raw idea about plot is correct....but mistaken about giving
title....please neglect title
it should be as
title ---> 13aug 14aug 15aug
WUCM plot0 plot1 plot2
vertical scale for WUCM and NOUCM vertical scale for
WUCM-NOUCM
NOUCM plot3 plot4 plot5
(WUCM - NOUCM) plot6 plot7 plot8
WUCM, NOUCM and (WUCM - NOUCM) is left axis string....title and string I
can provide....about scale doubtful as well as arranging plots from top to
bottom
