NEW FEATURE: Implement better selection of colormap #7

Closed Chilipp closed 4 years ago

Chilipp commented 4 years ago

Summary

There are way more colormaps available and it would be nice to select them independent from the current push button

Reason

more freedom

Detailed explanation

One possibility (and probably the easiest) would be to include a colormap dialog as it is already implemented for psy-simple (see Screenshot below) for the psyplot-gui. @tobstac: Do you think this is appropriate or do you have any other ideas?

Examples

I'd like this solution. Maybe you could reduce the width of the dialog window somewhat by using much smaller boxes for the single colors or even show a continious colorbar. This way it might be possible for users to see their data and the possible colorbars at the same time, which could help when deciding for a colorbar or playing around.

In fact, the current dialog does this, it adjusts the colormap based on the number of levels. Note that there is no continuous colormap, usually a colormap is built upon 256 discrete colors. So if you choose a high number of colors (or matplotlib.colors.Normalize), you will see a continuous colormap.

But my plan is, to redesign the current color settings dialog, and I'll add a preview for the chosen settings
