plotting two op parameters simultaniosly

Hello , I am trying to plot simultaniosly rout and region op on the same plot.

A Ids rout,Ids region,(both as a function of vds) were created succsesfully, however when i do one plot and select append plot on ADEL and try to append region plot into it,it shows a flat region=0 (cuttof) plot.

Athough its not the situation as shown in the (Ids region only) plot shown bellow

when did i go ploting region and rout OP on the same plot?

Thanks
