Colorbars belonging to more than one subplot/axis

Good evening,

I want to plot four different variables var1, var2, var3, var4 as color values on a triangular mesh. The first two variables should be represented by one single colorbar and the last two variables by another colorbar. By which commands can I achieve this?

Thank's a lot for your help!

figure(1)

set(gcf, 'Position', [100, 800, 1400, 300])

ha=tight_subplot(2,2,[0.08 0.05],[0.1 0.01],[0.0 0.1])

axes(ha(1))

trisurf(T,x,y,z,var1)

axes(ha(2))

trisurf(T,x,y,z,var2)

axes(ha(3))

trisurf(T,x,y,z,var3)

axes(ha(4))

trisurf(T,x,y,z,var4)

Do you have an example of what you'd like it to look like? Also, include function tight_subplot so we can run your code.

It should look like in the attached image! The upper two plots for var1 and var2 should be represented by the first colorbar and the two bottom plots for var3 and var4 by the second one.

perhaps something like this:

figure(1)
cx_12 = [min(min(var1(:)),min(var2(:))),max(max(var1(:)),max(var2(:)))];
cx_34 = [min(min(var3(:)),min(var4(:))),max(max(var3(:)),max(var4(:)))];

set(gcf, 'Position',  [100, 800, 1400, 300])
ha=tight_subplot(2,2,[0.08 0.05],[0.1 0.01],[0.0 0.1])
axes(ha(1))
trisurf(T,x,y,z,var1)
caxis(cx_12)
axes(ha(2))
trisurf(T,x,y,z,var2)
caxis(cx_12)
colorbar
axes(ha(3))
trisurf(T,x,y,z,var3)
caxis(cx_34)
axes(ha(4))
trisurf(T,x,y,z,var4)
caxis(cx_34)
colorbar

Thank's a lot! I tried your code and it works perfectly!
