bar3 color

Hello,

I have been using bar3 to plot a matrix. The matrix is 101x 201. When I use bar3, it plots bars of the same color for the short axis, but changes the color for the long axis. For example, my matrix is A(201,101). Matlab plots A(1,:) of the same color, but instead, I want it to plot A(:,1) of the same color. I have tried using bar3(A') but this does not help. Does anyone have sugestions?

Many thanks

I believe this will work for you. Basically I am resetting each set of bars colormap by changing the CData of the patches that make up the bar. I kept the original plot as a reference in this example.

A = rand(101,201);
figure;
hc = bar3(A);
figure;
h = bar3(A);

for ii = 1:length(h)
    zdata = get(h(ii),'ZData');
    colorEx = repmat((1:length(zdata))',[1 4]);
    set(h(ii),'CData',colorEx)
end

If I understand the question correctly, the code works when zData and not colorEx is used as color information:

set(h(ii),'CData',zdata)
