Hello everyone
I want to do a conditional overplot like
if a eq 'A' and b eq 'B' then not oplot,x,y
I mean that if the two conditions are satisfied then don't do the overplot. How can I do this? Could someone please help me?
Thank you in advance

Well, I can think of at least 2 ways:
; Reverse the logic!
if (a ne 'A' || b ne 'B') then oplot,x,y
; Dorky, but keeps the logic
if (a eq 'A' && b eq 'B') then begin
endif else begin
oplot,x,y
endelse

IF (a NE 'A') OR (b NE 'B') THEN OPlot, x, y
