Hi all,

I've plotted 2 different datasets of points in a 2D coordinate system (same coordinate system) using scatter. My data is a 3 column matrix where first column is x-value and second column is y-value. I then want the different point to be different colors depending on the value in the third column. I can create easy while plotting with scatter and then adding a colorbar but then the 2 different datasets gets the same range of colors and the same colorbar.

How get 2 different color ranges and colorbars for the 2 different datasets in the same figure? I can get this in two different figures adding colormap('gray') in of of them and colormap('cool')in the other figure, but I would like to have this in the same figure.

Do you really mean the same figure or the same axes? i.e. if you have a sufficiently recent Matlab (I forget which version off-hand, maybe around R2015) then putting different colourmaps on different axes within the same figure is trivial as colourmaps are now per axes rather than per figure.

If you actually mean the same axes then it is more complicated, especially if you want 2 colorbars with them.
