Plotconfusion - How to adjust size?

Hello,

I am using the plotconfusion command to plot a confusion matrix. There are approximately 23 classes and the result of the plotconfusion command is a graphical confusion matrix, but the numbers are all scrunched up and on top of each other (impossible to read). I am ultimately trying to save the confusion matrix displayed to a png file, I really don't care about the display of it.

The closest I have found to a solution is to do something like: set(gca,'Units','normalized'); set(gca,'Position',[0 0 1 1]);

And then to save the confusion matrix that displays to a PNG file.

On my work computer, this still doesn't even give acceptable results because my screen simply isn't big enough. It also cuts off the bottom X axis labels. But on my home computer, the screen is bigger and the resized confusion matrix is almost acceptable, but still the numbers are not aligned. I have also been successful at making the font smaller (~6pt) and this works, but really I don't want to have to do that. I want to just produce a big image that we can scroll around on. To do this, do I really need to have a monitor the size of the image I want to produce?

My question is how can I save the PNG file and make the confusion matrix an arbitrary size without having to resort to maximizing the figure on my home computer and resizing the figure?

Thank you,

C

hi i have the same problem did u found the solution ?

Hi all, this is late but if you're still curious, use the Windowstate property like figure('WindowState','maximized') to get it maximized after calling the plotconfusion function.

Really, this is a good case for export_fig()

Using 'windowstate' is only an option in R2018a and up.
