How to create one common colorbar and colorscale for subplots

Dear all,
I would like to add one common colorbar to all subplots shown below. Here it is very important that the all subplots should be on the same color scale. Subplot (4,2,4) with max 60 rain rate should then be showing much more yellow pixels than the other ones. I cannot find a way to do this within the loop below. Help is very much appreciated. :-) I am using the subplot function https://de.mathworks.com/matlabcentral/fileexchange/3696-subaxis-subplot to decrease the empty space between the subplots.
lat = load('latS.mat');
latS = lat.latS;
lon = load('lonS.mat');
lonS = lon.lonS;
rain = load('rain_test.mat');
rain_test = rain.rain_test;
figure
for i = 1 : 8;
subaxis(4,2,i, 'Spacing', 0.03, 'Padding', 0.0, 'Margin', 0.03);
pcolor(lonS,latS,rain_test(:,:,i));shading flat
%geoshow('landareas.shp', 'facecolor', 'k');
xlabel('longitude (°)'); ylabel('latitude (°)');
%h=colorbar;
%set(get(h,'ylabel'),'String','Rain rate (mm/h)');
hold on
plot(179.5,-14.2,'r*')
axis tight
axis off
end

You need to add in the following inside the loop for each subplot:
caxis([0 60]); % adjust the number 60 or find the value from all data first
