[Octave-bug-tracker] [bug #47974] Visual differences between gnuplot and OpenGL toolkits

[Ben Abbott]

Follow-up Comment #20, bug #47974 (project octave):

The problem with vertical placement of the axis titles for 3D plots (demo
ezsurf 3) is triggered by setting the margins. The problem can be compensated
for by offsetting the title, but the calculate needed is complicated and
relies upon the size of the figure window which Octave cannot know (since it
maybe modified by the user/mouse).

The improper aspect ratio of 3d plots is likely due to both the setting of the
margins and to the lines below (from __gnuplot_draw_axes__.m)


  90         ## 3D plots need to be sized down to fit in the window.
  91         x = 1.0 ./ sqrt ([2, 2.5]);


This also relies upon the size of the figure window, which Octave cannot know.
