I am trying to make a graph with two different contourf subplots that use completely different colormaps. However with the code I currently have (which creates a custom colormap for one of the subplots), the subplots come out with the same colormap. Any ideas how to fix this?
h = figure;
subplot(2,1,1)
title('GEFS 20 Member Mean Vorticity');
axesm('eqdcylin','maplonlimit',[-180 179],'maplatlimit',[0 90]);
%eqdcylin
contourm(gLat, gLon, squeeze(meanhx(x,:,:))', 16,'Color',[0.05 0.05 0.05],'LineWidth',2);
hold on
contourfm(gLat, gLon, squeeze(vmeanx(x,:,:))', 30, 'LineStyle', 'none');
shading flat;
lm=worldlo('POline');
for i=1:length(lm);
lm(i).otherproperty = {'color','m','LineWidth',1.5};
end
displaym(lm);
gridm on;
tightmap;
set(h, 'Position', [1 1 2200 1100]);
colormap(b2r(-5*10^-5, 5*10^-5));
freezeColors;
cbfreeze(colorbar)
%caxis([-5*10^-5 5*10^-5])
colorbar;
subplot(2,1,2)
title('GEFS 20 Member Vorticity Variance');
axesm('eqdcylin','maplonlimit',[-180 179],'maplatlimit',[0 90]);
%eqdcylin
contourm(gLat, gLon, squeeze(meanhx(x,:,:))', 16,'Color',[0.05 0.05 0.05],'LineWidth',2);
hold on
contourfm(gLat, gLon, squeeze(vvarx(x,:,:))', 30, 'LineStyle', 'none');
shading flat;
lm=worldlo('POline');
for i=1:length(lm);
lm(i).otherproperty = {'color','m','LineWidth',1.5};
end
displaym(lm);
gridm on;
tightmap;
set(h, 'Position', [1 1 2200 1100]);

It's possible to make subplots of different sizes by specifying a multiple-element vector for the grid position argument p in the syntax subplot(m,n,p) .
subplot( m , n , p ) divides the current figure into an m -by- n grid and creates axes in the position specified by p . MATLAB® numbers subplot positions by row. The first subplot is the first column of the first row, the second subplot is the second column of the first row, and so on.
There is a command suptitle, which puts the title of all subplots.
EDIT: it seems, that the documentation is wrong! See comments!
By using the second argument of the colormap function, one should be able to assign a specific colormap to a specific (sub-)plot or axes, if you want to call it like that:
Referring to TMW: colormap:
Be aware that the first argument is the handle to the axes!
colormap(ax,map)
sets the colormap for the axes specified by ax. Each axes within a figure can have a unique colormap. After you set an axes colormap, changing the figure colormap does not affect the axes.
How to get the handle of the axes?:
when plotting with plot(x,y..) you get it as the return-value. Catch it with:
ax = plot(x,y..)
For other plot-functions, as you seem to use, you should find some info about that within the doku.
If you upgrade to MATLAB 2017a, you can assign a colormap to each axes object using the syntax colormap(axesHandle, cMap)
