Hello,
I have a barplot with two groups plotted next to each other (see code below). I cannot for the life of me get the bars to be black and white - they are always printing as the default red/blue, despite what I think is code that should work. Any help is much appreciated. Thank you!
subplot(2,2,1)
clr = [0 0 0; 0.9 0.9 0.9];
colormap(clr);
a = [percentsQ1' percentsQ1N'];
bar(a);

Need to apply the colormap to something...
hAx=subplot(2,2,1);
clrs = [0 0 0; 0.9 0.9 0.9];
colormap(hAx,clrs);
hB=bar([percentsQ1' percentsQ1N']);
or you can use set() to set the bar handle properties directly...
set(hB,{'FaceColor'},{clrs(1,:),clrs(2,:)}.')
