Visual comparison of plot files from http://josoansi.de/octave_plot_compare/compare_plot_demos_01.html until compare_plot_demos_0_08.html
- Page 1: annotation .. colorbar
- Page 2: colorbar .. ezplot
- Page 3: ezplot .. legend
- Page 4: legend .. meshz
- Page 5: meshz .. quiver
- Page 6: quiver .. slice
- Page 7: slice .. trisurf
- Page 8: trisurf .. zoom
You can find the scripts which are used to create these plots in scripts/testfun/private.
FLTK, Qt
- [josoansi.de/octave_plot_compare/compare_plot_demos_01.html#axis_09] 9,10,11,12, 13: No XAxisLocation zero (bug #40588)
gnuplot
- 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
FLTK, Qt, gnuplot
- annotation_03: currently not all "headstyle" properties implemented which matlab has
- annotation_04: ???
- area_01: Different colors, white vertical lines in FLTK/Qt
- cmpermute_01: No plot
Matlab errors due to incompatibilities
- autumn_01: Error using rgbplot. Too many input arguments.
- axis_03: Error using axis (line 204). Unknown command option ticx.
- axis_04: Error using plot. Error in color/linetype argument.
- axis_06: Undefined function 'sombrero'
- axis_09,10,11,12, 13: No XAxisLocation zero
- bone_01: Error using rgbplot. Too many input arguments.
- brighten_01: Error using axis (line 204). Unknown command option ticy.
old results with broken links, should be checked and merged
- gnuplot + fltk colorbar_23: xtick unreadable. It should check the text_extent and reduce xticks if the xlabels would overlap.
- gnuplot + fltk colorbar* : 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.
- fltk colorbar_19.png : unusable colorbar with FLTK (bug#42311) when log scale is set, fine with gnuplot
- gnuplot + ftlk: fill_01, fill_02: hidden edges keep visible in ML, not with fltk or gnuplot. This seems to be a ML bug when printing to PNG or JPEG and works (same output like gnuplot+fltk) when printing to ps. In FLTK the on-screen images shows the hidden edge and becomes invisible when printing.
- gnuplot + fltk: hold_07: red rectangle hides the '^' plot markers. In ML they disappear on-screen as soon as xlim is changed or zoomed. Is this a ML bug? What is the prefered behaviour?
- fltk colorbar_20: Latex label 10^{2}, 10^{1.5} not in print output. See bugs #42988, #42320, #42340 which are mostly duplicates
gnuplot only differences
There are a lot of gnuplot differences and it might be nice to fix those, but someone would have to take an interest. Octave is moving towards OpenGL for all plotting so most developers focuses on bug fixes for that toolkit.
Nevertheless here are some visual gnuplot ONLY problems which need some attention:
- gnuplot fill_03: unusable
- gnuplot ezsurf_02: distorted despite "axis equal"
- gnuplot isosurface_01: wrong scale, edges missing
- gnuplot zlim_03: Warning/Error "line 0: *All* edges undefined or out of range, thus no plot." and an empty plot (as announced). FLTK plot is fine.
work in progress
- plotyy_03: chunky dashed line for the '--' linestyle: Thread on ML
fixed
- colorbar ticks: http://hg.savannah.gnu.org/hgweb/octave/rev/04a00ba54557
- gnuplot + fltk compass_01: no proper scaling/zoom: A changeset from Stefan Mahr fixing a different part of polar() also solves the auto-scaling issue with compass(). See http://hg.savannah.gnu.org/hgweb/octave/rev/cff49c82f722.
- The right axis of the Pareto plot was being drawn in a different color from the left axis. http://hg.savannah.gnu.org/hgweb/octave/rev/f1e21a495e20
- gnuplot + fltk patch_04: the demo incorrectly assumes the patch "facecolor" is "flat" as octave currently sets this by default (whereas in matlab "facecolor" is "none" by default). This should be fixed with bug#42159 (this probably is also the cause for black faces in shrinkfaces*)
won't fix or Octave only feature
- fltk/ML axis_09, axis_10, axis_11, axis_12, axis_13: No, [x,y]axislocation' 'zero' (http://savannah.gnu.org/bugs/?40588). This is an Octave (and gnuplot) only feature. We can either blacklist, or visually skip over the comparison since it is blank for Matlab. Perhaps should be removed from demos or blacklist axis_09 in dump.m script
- 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.
