Custom labels in colorbar

[RPeschke]

added support for custom Tick labels on color bar

code:

f= figure();
h=pcolor(peaks);

hcb=colorbar;
set(hcb,'YTick',[-6 0 6 ],'YTickLabel',{'Good','Normal','Bad'})
matlab2tikz('figurehandle',f,...
    'filename','example_colorMap.tex' ,...
    'showInfo', false,...
    'standalone', true);
close(f)

Can a developer please verify this PR for testing?

@matlab2tikzBot please test this

There is a typo in the function name.

[miscco]

Thank you very much for that PR. That is a good usecase and will definitely improve m2t.

However, I think the code is not there yet. Especially considering that we already have an infrastructure for TickLabels. From a glance at

function [options] = getAxisTicks(m2t, handle, axis, options)

I would guess, that you could achieve all that you want by passing an empty "axis" argument. Maybe we will need some checks against that but I think that might be a suitable approach.

[RPeschke]

Thanks for your succession I found that all the functionality was already in the project I just needed to apply it to this axis label type.

[miscco]

Here you can just pass cbarStyleOptions directly.

[m2t, cbarStyleOptions] = getAxisOptions(m2t, handle, 'y', cbarStyleOptions);

Then there is no need to merge below.

[miscco]

Additionally getAxisOptions assumes that options is a valid container, so that would break most likely

I am unsure about the attached pdf/jpg. They generally do not make thatmuch sense if you are not a developer.

@egeerardyn thoughts?

[egeerardyn]

@miscco I agree. Attaching the produced output makes little sense for a normal user, I would say. So it's probably better to remove them from the repository.

We should add the feature to getColorbarOptions() mostly as is, and eventually clean up the code in another PR.

For this, we need:

• drop the .pdfs and .png
• drop opts_append_unique(), not sure what purpose irt serves, since it's not used
• adapt one of the existing ACID example to use custom colorbar labels, akin to the provided example. We do not want proliferation of test cases...
