How to flip x & y axes of a colorbar

I want to put a colorbar in a figure and have the colorbar horizontally span the length of 3 subplots underneath them. How can I do this and have the colorbar values scale horizontally instead of vertically?

myfig=figure; 
subplot(1,3,1); 
sp1=plot(1,1,'o', 'markersize', 40, 'markerfacecolor', 'b');
set(gca, 'visible', 'off'); 
subplot(1,3,2); 
sp2=plot(1,1,'o', 'markersize', 40, 'markerfacecolor', 'g'); 
set(gca, 'visible', 'off')
subplot(1,3,3); 
sp3=plot(1,1,'o', 'markersize', 40, 'markerfacecolor', 'r'); 
set(gca, 'visible', 'off')
colbar=colorbar('Position', [.25 .1 .5 .05]);

I know I could set the colorbar to be 'south' of subplot 2, but then it won't be as wide as I want.

I was able to do it by making a colorbar 'south' of the 2nd subplot, then changing the position.

So, problem solved, but if anyone knows how to flip the x & y axes of a colorbar without setting the 'location' to 'south' or 'north', that'd be appreciated.

myfig=figure; 

subplot(1,3,1); 
sp1=plot(1,1,'o', 'markersize', 40, 'markerfacecolor', 'b');
set(gca, 'visible', 'off'); 

subplot(1,3,2); 
sp2=plot(1,1,'o', 'markersize', 40, 'markerfacecolor', 'g'); 
set(gca, 'visible', 'off')

colbar=colorbar('Location', 'south', 'Position', [.25 .1 .5 .05]); 

subplot(1,3,3); 
sp3=plot(1,1,'o', 'markersize', 40, 'markerfacecolor', 'r'); 
set(gca, 'visible', 'off')
