Dear Herbert,
I have a small trouble with pstricks-add and especially the hyperbolic functions.
I like to use the RPN system for my 'psplots' and 'parametricplot' but with the hyperbolic functions (ch sh, ...) I only succeed with the algebraic notation.
With the example file below, it is OK with the yellow lines removed. I have also tried pst-math which defines also hyperbolic functions and there there is no trouble.
Is it a limitation of pstricks-add to only allow algebraic=true for the new functions defined in section IV of pstricks-add namual version November 6, 2006?
Thanks for your collaboration.
