You can not add points to CDEF variables. I was thinking that if I catch a case of line intersecting threshold I can substitute threshold value instead of current point. However RPN expression for this looks rather complex and I did not figure it out yet :(. I am thinking of adding function to the RPN calculator which will return value of the threshold if it is crossed by CDEF variable or current value of the CDEF variable.
But at least I can do this for AREA type graphs. On Wed, 30 May 2001, Serge Maandag wrote: > > I'm using the same setup as you do.
