I am plotting the results of cross correlation on a bar3 figure. At times, a lot of the values are 'close' to each other, so instead of plotting the bars over the entire range of scores, I'd like to limit the plot to just between the minimum and maximum values of the correlation. When I set the ZLim property, the z-axis scale is correctly set, but the bars themselves extend through the bottom of the chart (trying to find 0). How do I limit the size of the bars themselves?
%for the sake of this question, lets assume the correlation returns
x = 0.9 + (1-0.9).*rand(10,10);
inputs = 1:5:51;
figure
h = bar3(x);
set(gca, 'XTickLabel',inputs);
set(gca, 'YTickLabel',inputs);
set(gca, 'XTick',1:length(inputs));
set(gca, 'YTick',1:length(inputs));
set(gca, 'XLim', [0 length(inputs)+1]);
set(gca, 'YLim', [0 length(inputs)+1]);
set(gca, 'ZLim', [min(min(x)) max(max(x))]);

I suggest:
% Create the ‘xt’ variable:
xt = x - min(min(x));
% Change the ‘bar3’ call to:
h = bar3(xt);
% Add these lines to your code after the ‘bar3’ call:
ztiks = floor(linspace(min(min(x)), max(max(x)), 6)*101)/100;
set(gca, 'ZTickLabel', ztiks');
% Delete or comment-out this line:
set(gca, 'ZLim', [min(min(x)) max(max(x))]);
I got this plot:
