How can I change color and font size in plotconfusion figures?

16 views (last 30 days)
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!

My confusion matrix size is 19x19.. so, Is there any convenient way to display clearly...because u know when 19x19's confusionMatrix plot it's a overlap some value...n everything hochpoch !!!
Thanks for Advance...

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)
