Hi

I use the following easy script do plot some functions in subplots:

x = [1  3 4 5];
y = [2.3 4.1 5.2 -1];
z = [1 1 1 1];
a = [12 13 44 1];
subplot(2,2,1); plot(x)
subplot(2,2,2); plot(y)
subplot(2,2,3); plot(z)
subplot(2,2,4); plot(a)

But when I run the programm, although no error message occurs, also no plots are displayed. Why so? Thanks

The only thing I can think of is that your current figure window is either off your screen somewhere, or has the 'Visible' property set to 'off', so that it is not displaying.

What do you get for the 'Visible' property if you type

get(gcf)

Also, do you see the plots if you add a figure command in front of your plotting commands?

figure
x = [1  3 4 5];
y = [2.3 4.1 5.2 -1];
z = [1 1 1 1];
a = [12 13 44 1];
subplot(2,2,1); plot(x)
subplot(2,2,2); plot(y)
subplot(2,2,3); plot(z)
subplot(2,2,4); plot(a)

Failing that, I would restart MATLAB, and/or restart your computer. Not sure what to try other than that.

So, I tried it again and still I see no plots.

Again to repeat what I have done so far: the code

x = [1  3 4 5];
y = [2.3 4.1 5.2 -1];
z = [1 1 1 1];
a = [12 13 44 1];
subplot(2,2,1); plot(x)
subplot(2,2,2); plot(y)
subplot(2,2,3); plot(z)
subplot(2,2,4); plot(a)

has been saved in a .m file and I would just press the "run" button.

When I add "figure" I get an error:

Error using figure Error using figure Error using figure UIJ_AreThereWindowShowsPending - timeout waiting for window to show up

Error in Ex_1 (line 1) figure

And get(gcf) doesn't work either...:-/

I am not familiar with that error, but it suggests that MATLAB is somehow stuck trying to open a figure window.

You could try

>> close force all hidden

to try to shut all figure windows (and hopefully the pending one), and then try to run your code again.

Does this happen with a brand-new instance of MATLAB, in which you have not run any other commands? If so, that is extraordinarily weird to me, and I have no further suggestions other than to contact MathWorks support.

So I had this problem as well, and after messing around for a long time, I found a fix - there seemed to have been an issue with the image renderer it was trying to use. Setting

set(gcf,'Renderer','zbuffer')

Fixed the problem for me (I haven't tried it for different renderers, and I still don't know why this might've happened, without an error message)
