What code to make figure window fullscreen with subplot?

Hello everyone,

I am not a huge matlab user, I know the basics but I don't use it that much.

I created a script that opens a .txt file containing datas from an experiment, reads it, extracts the informations needed, plots 3 curves in a unique figures and then saves the figure created as a .jpg. It works fine, except it saves the Figure (3 subplots) as it appears in the "reduced" window, and I want to save it as the fullscreen window. Basically what I want to do is to add a line of code right before I save the picture that will make the Figure window fullscreen.

I saw some solutions like:

set(B,'PaperPositionMode', 'auto')
set(B,'Units','Normalized','Outerposition',[0 0 1 1]);

that work for only one plot, but when I tried to use it for my 3 plots it ended up making the third set of datas take the whole screen. Basically all I could find on internet doesn't seem to work for subplots.

Here is my code, do you have any suggestions?

Many thanks

So you want to maximize the figure before making the image?

[Théo Liénard--Mayor]

Yes exactly

Answer 1

[Rik]

You can use my maximize FEX submission, and/or if you're using R2018a or later you can set the WindowState property (see the documentation for all the options: link).

set(gcf,'WindowState','maximized')

[Théo Liénard--Mayor]

Thank you, your maximize function works, altough I am not getting exactly the same thing in my file and in my Octave display. This is what Im getting in my Octave display (just with the code, no modifiction with the mouse.)

And this is what I'm getting in my .jpg file

I don't really understand why I have this difference, in my opinion the figures are more beautiful in the first case, but the second case will do for now.

Anyway, thank you for your help!

[Théo Liénard--Mayor]

Here the modified code with your function:

If I recall correctly I just made the font size smaller until the output matched what I needed when I ran into this issue with Octave. The renderer is not super well-documented in Matlab, but for Octave on Windows it's even worse. If you can get Java to work reasonably well, you can use the FEX submission by Yair Altman to get a capture of your screen, instead of relying on a re-rendered output.

Answer 2

[Bruno Luong]

Check out This thread hope it's not obsolete. If you run on Windows WindowAPI (Jan's reply) is the only one which makes real full-screen display (no border...)

[Théo Liénard--Mayor]

Hello Bruno,

I did find this thread while looking for the solution before posting my question, I tried the different suggestions but it ended up not working for me, but maybe I didn't use the suggestions correctly.

Anyways, thank you for your help!

[Bruno Luong]

Here is the image I get win WinAPI (I have an old version, syntax might varies)

plot(rand(1,100))
WindowAPI(get(gcf,'Number'),'Position','full')
