problematic, because it's not a "linear" plotting paradigm. A GUI responds to
user input to and displays plots based on that, no pressing return needed for
anything. Unless I'm misunderstanding what's being proposed, I don't think
anything about hitting retur
urer with the function evaluator
technique to deal with the issue of C vs Fortran vs whatever array storage.
Worked out nicely IMO. Would've liked to upgrade all array-handling functions
in like fashion but so far I think it's only been done for the plshadexx
family.

Hi Alan,
I'm somewhat in the dark about xwin focus issues. I recall Tk goes to some
trouble to "do the right thing" about it, and maybe that's the problem here.
The demo was originally envisioned as testing ground for more arcane scenarios
involving the Tk driver; I'm a little amused/surprised it
In order to run TK code that uses plplot extensions, you need an extended wish
that knows about these extra commands. That's what plserver is for (it also
has some IPC for handling requests from the plplot TK driver which is why it's
not simply called "plwish".. too bad, that would've been more tr
