view scripts/plot/__plt_get_axis_arg__.m @ 17036:08dd9458684a
Overhaul __plt_get_axis_arg__ and newplot functions to avoid creating unnecessary axes.
* scripts/plot/__plt_get_axis_arg__.m: Only return an axis handle if found in
argument list. Do not create any figures or axes.
* scripts/plot/newplot.m: Overhaul to allow specifying an axis handle input.
Prepare figure and axes according to Matlab conventions.
* scripts/plot/line.m: Never call newplot() for a core graphic object.
Always plot into gca.
* scripts/plot/plot.m: Update to use new __plt_get_axis_arg__ and newplot
functions.
