Well, you can't. At least not if you insist on the axes
being drawn on a widget base. :-)
But you could fake it easy enough. Create a compound
widget consisting of three draw widgets. Be sure to use
no xpadding, ypadding or space for your widgets as you
put these together. The top and side draw widgets are
for your axes, and are thin, narrow widgets nestled up
against the draw widget you will use for graphics.
Make the background color of the axes draw widgets
the same color as an empty base widget. For example,
WSet, leftAxisWid
Erase, Color=FSC_COLOR('face')
Now draw your axes on these two widgets.
They should look *exactly* like they are drawn on a
base widget. :-)
As a compound widget, you will have control of
how you put things into the main draw window, so
you can suppress axes there, etc. Neat.
Cheers,
David
