Re: [Plplot-general] (no subject)

Ok, I understand this a bit.  The 'Plplotter' package is the one achieved
by using the windows-specific makefile from my changes over the last
couple of years, using the 'tkwin' driver.  It only exposes the 'plframe'
widget and associated megawidgets to the level of Tcl/Tk.  The API Rayal
is referring to is that achieved through 'Pltcl_Init' which simply isn't
in it.

Rayal: for someone who knows the relevant APIs, it shouldn't be hard to
compile a different version which exposes the stuff you are trying to use,
but I think you will find it easier just to use plplot via 'plframe', so
do this:

package require Plplotter
plframe .p

and then wherever you see a command 'plinit', 'plcol0' etc, use instead:

.p cmd plinit
.p cmd plcol0 ...

etc.

cheers,
