You can find the scripts which are used to create these plots in scripts/testfun/private.

Qt

• axis_09,10,11,12, 13: No XAxisLocation zero (#40588 and #48562) since Matlab R2016a now supports "origin", this should be considered as an compatibility bug
• copyobj_01: Second line, legend and marker missing
• colorbar_19: no colorbar
• hold_06: transparency?
• imshow_07: ???, gnuplot does the same as matlab...
• fill_01: Hidden edge is visible

• stem_06: Vertical lines to the marker missing
• stem_07: Vertical lines to the marker missing

gnuplot 4.6

The monochrome prints are reported here #48832

• annotation_02: gnuplot boxes are wrong
• annotation_05: gnuplot uses dotted lines instead of solid line
• annotation_06: annotation is shifted
• area_01: legend is cutted
• axis_02: xy plot yaxis inverted
• colorbar_01: inverted colorbar
• colorbar_02: horizontally swapped colorbar
• colorbar_07: upper right colorbar is inverted
• colorbar_08: right colorbar is inverted
• colorbar_12: right colorbar is inverted
• colorbar_14: upper colorbar is inverted
• colorbar_20,21,22,23: inverted colorbar
• fill_03: no gradient
• hot_01: lower plot yaxis inverted

Qt and gnuplot (independent of the used graphics_toolkit)

• annotation_03: currently not all "headstyle" properties implemented which matlab has
• annotation_04: ??? What's correct here?
• area_01: Different colors, white vertical lines in FLTK/Qt
• cmpermute_01: No plot
• colorbar_23: xtick unreadable. It should check the text_extent and reduce xticks if the xlabels would overlap
• colorbar_01: This is just a matter of taste but I (Andy1978) would prefer a smaller gap (only 40% of the current implementation?) between colorbar and the plot like matlab does

Matlab errors due to incompatibilities

• axis_03: Error using axis (line 204). Unknown command option ticx.
• axis_04: Error using plot. Error in color/linetype argument.
• brighten_01: Error using axis (line 204). Unknown command option ticy.
• colorbar_19: Error using matlab.graphics.illustration.ColorBar/set. There is no yscale property on the ColorBar class.

won't fix or Octave only feature

• matlab comet3_01, comet.png: Only the beginning of the animation is printed. Matlab implements comet in a completely different way which means printing isn't really possible for them.
• matlab polar_03, polar_05: Modifying ticks for rho (rticks) and theta (tticks) is an Octave addition.
• matlab polar_04: Modifying color and text properties in polar plot is an Octave addition.
• Multiple Matlab plots with "Error in color/linetype argument". This is because adding legend keys with ";" in plot like "plot(1:10, "; a ramp;)" is an Octave only addition.
