User-defined palette for image plots about jkqtplotter HOT 4 CLOSED

Hi!

that's one of the open things I still wanted to tackle ... so I would be happy to look over such a commit! ... You should also put your extension into JKQTPColorPaletteStyleAndToolsMixin (used for colored scatter-plots etc.) as at some point that will be used by JKQTPMathImage (currently that's still partly doubled code)!

In addition I was planning on reactivating a system that is in place for some time and allows to read palettes from files. That way it will be possible to register palettes (either user-defined, or from files) with IDs above JKQTPMathImagePREDEFINED_PALETTES_COUNT at a central place and they can simply be used by defining palette JKQTPMathImagePREDEFINED_PALETTES_COUNT+1, JKQTPMathImagePREDEFINED_PALETTES_COUNT+2, ... (enum is more or less simply an INT ;-)

So ... looking forward to you extensions!

PS - Great to hear you like the lib ... what are you using it for?

Hi again!

just a short word of warning ... I'm currently reworking the palettes backend system (types and all) ... so you might want to wait until that is pushed to the repository!

Hi!

please have a look at my last commit 9f694a9 ... maybe that already solves your task?

There is also a new example for user-defined palettes with a tutorial:

Thanks Jan - that's just what I needed.

I'm using the library to plot the results of analyzing RF signals of various kinds: image plots (spectrograms), line plots etc.

Thanks again,
