Hi, I want to plot like this figure.
My question is how to get colorbar like this one, the shape of the figure( like this map) doesn`t matter( Now it`s a gobal spatial pattern, it could be anything else)
at each point on the map, I have 2 values, mapping to one color in the two dimensional colorbar.

As mentioned, there is no functionality for a 2d colourbar in Matlab, but you can create your 2d image representing your 2d colourmap easily and just plot it using imagesc on its own axes that you can position wherever you want.

Here is a way:
clc,clear
n = 100;
I = zeros(n,n,3);
h = linspace(0,1/6,n);
s = linspace(1,0,n/2);
[H,S] = meshgrid(h,s);
I(:,:,1) = [H+0.5; H];
I(:,:,2) = [S; flipud(S)];
I(:,:,3) = [S; flipud(S)]/2+0.5;
I1 = hsv2rgb(I);
imshow(I1)

I don't think Matlab has anything that can do this nativly, but I will follow just incase any has a better idea then me.
My thoughts...
Generate an image/matrix that is what you want you color bar to look like. Use the subplot function to plot your image/map and your colorbar image next to each other.
