== 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:
 
 
* fill_03: unusable
 
* ezsurf_02: distorted despite "axis equal"
 
* isosurface_01: wrong scale, edges missing
 
* trimesh_01: invisible lines [http://savannah.gnu.org/bugs/?42561 bug#42561]. FLTK plot is fine.
 
* 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.

Visual comparison of plot files from http://josoansi.de/octave_plot_compare/compare_plot_demos_01.html until compare_plot_demos_0_08.html

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

Qt

gnuplot 4.6

The monochrome prints are reported here #48832

Qt and gnuplot (independent of the used graphics_toolkit)

Matlab errors due to incompatibilities

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.
