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

47 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!

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)
