Obtain uniform color of point when plotting UV plane #123

Open Bruccos opened 6 months ago

Bruccos commented 6 months ago

Hi,

I'm trying to plot the UV plane and I see the points get colourized by their density with the colorcet maps. However, I would like for them to be all of the same color. Is it possible?

Ps: I saw that I can colour by a quantity common to all point to have them all the same colour, but in that case I obtain also the colour axis on the right that I don't want.

Thanks a lot.

Ha, sometimes it's the simplest features that one overlooks! I believe we don't have that feature...

However, maybe you can work around it by picking a monochrome colormap and dialling up --min-alpha or --saturate-alpha?

Thanks for the quick response!

I've tried your suggestions, but unfortunately it seems that they have no effect unless i specify a given -aaxis. In this way I'm able to obtain a monocolour figure by selecting a common parameter (e.g. CORR), however once again it appears also the unwanted color bar on the right.
