# 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)

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
