Thanks, Maurice, I see that now in plfcont and plfshade. I think that's just the kind of thing that would be great to have for every function that deals with >1-D data. I'm willing to try my hand at adapting some other functions to use this technique. As far as I can tell, the list of functions that could benefit from this are... c_plgriddata (*) c_plmesh (**) c_plmeshc (**) c_plot3d (**) c_plot3dc (**) c_plot3dcl c_plimagefr (***) c_plimage (***) c_plsurf3d (****) c_plsurf3dl c_plvect (*****) (*) c_plgriddata might need both a "getter" and a "setter" version of this technique. (**) calls through to c_plot3dcl (***) might need a "plf..." version of plMinMax2dGrid (****) calls through to c_plsurf3dl (*****) already has a plfvect in plvect.c, but not plplot.h! My plan would be to rename the existing functions from "c_pl..." to "plf..." (or "c_plf..."?) and create new versions of the old functions that call the "plf" variant "with a particular choice for f2eval and f2eval_data" (as the c_plcont comments say). The only downside to doing this, AFAICT, is that the current behavior of these functions will be somewhat slower since they will be getting data via the evaluator function and not directly from the "z[nx][ny]" array (at least for z arrays that don't need to be "pre-un- transposed" into that format). If anyone thinks that (or anything else about this idea) is a show- stopper, please let me know ASAP so I don't spend time implementing something that won't be incorporated.
