Hi!
I want to change the color of the fields of the confusion matrix and also to change the font size of the entries in the fields. I know I can do it in the plot editor, but I prefer to do it automatically perhaps with set and get? I couldn't find anything in google on that topic.
Thanks for your help!
Just a little example:
a=[1 1 0 1 0 0 1 0 1 0 1 1 0 0 1 0 0 0 1 0];
b=[1 0 1 1 0 1 1 0 1 0 1 0 0 0 1 1 0 0 1 0];
figure(1)
plotconfusion(a,b)

I got it! :)
For those who are interested in the solution:
%defining my colors
f1=[0 0 139]/255;
f4=[50 205 50]/255;
f9=[236 0 0]/255;
f14=[85 26 139]/255;
%example
a=[1 1 0 1 0 0 1 0 1 0 1 1 0 0 1 0 0 0 1 0];
b=[1 0 1 1 0 1 1 0 1 0 1 0 0 0 1 1 0 0 1 0];
figure(1)
plotconfusion(a,b)
%fontsize
set(findobj(gca,'type','text'),'fontsize',20)
%colors
set(findobj(gca,'color',[0,102,0]./255),'color',f4)
set(findobj(gca,'color',[102,0,0]./255),'color',f9)
set(findobj(gcf,'facecolor',[120,230,180]./255),'facecolor',f4)
set(findobj(gcf,'facecolor',[230,140,140]./255),'facecolor',f9)
set(findobj(gcf,'facecolor',[0.5,0.5,0.5]),'facecolor',f1)
set(findobj(gcf,'facecolor',[120,150,230]./255),'facecolor',f14)
Not very elegant, but it works!

Did you find a solution? .... I have the same problem

Maybe with this number of classes you should consider another way of displaying the results, like a bar plot for example.

No, there is no convenient way. You would have to do the plotconfusion() and then find the created objects and move them into a large container that you had created scrollbars for.

Use the command from the accepted answer above just change the font size from 20 to 5, Iused it and it helped to better show a 26 class confusion matrix.
set(findobj(gca,'type','text'),'fontsize',5)
PS I know this is an old thread but I'm posting this reply to help whoever might needed!
