Follow-up Comment #2, bug #42311 (project octave):
Thanks Pantxo for the workaround, but I don't need it. It is not my own code
that is causing the problem, but rather the testsuite of matlab2tikz[1]. The
following function can be found among their tests[2]:
function [description, extraOpts] = colorbarLogplot()
switch getEnvironment()
case 'MATLAB'
imagesc([1 10 100]);
case 'Octave'
% TODO find out what to do for octave here
description = 'Logscaled colorbar -- unavailable in Octave.';
extraOpts = {};
return;
otherwise
error( 'Unknown environment. Need MATLAB(R) or Octave.' )
end
set(colorbar(), 'YScale', 'log');
description = 'Logscaled colorbar.';
extraOpts = {};
end
So, it seems that Matlab can handle a logscaled colorbar. I don't know if the
values are correct, but right now I care more about getting the testsuite to
run fully on Octave - that's why I am reporting issues I find during these
tests.
