Using plot(x,y) nothing appears.

Hello

I use Ubuntu 20:04.

At command window I write the commands:

>>figure()

>> plot([1 2 3],[4; 5; 6])

but not any line appears at the figure window.

No error messages just the figure window pops and then silence .

Thanks

[Torsten]

If these are the only two lines of code you use, contact TMW Technical Support:

Thanks Torsten .

I will give myself a try.

Is there any function named "plot.m" that you created by yourself in the list that you get on your computer ?

[Manolis]

No I can't give myself a try because I use Matlab as Trial Period.

Thanks anyway.

[Manolis]

I restarted Matlab,run the same lines and now I have some long messages about "rendering issues etc etc" .

Wish me good luck friends.

[Star Strider]

‘... rendering issues ...’

Check your graphics driver and update it if necessary.

[Manolis]

Thanks Strider. That's for I asked everybody to wish me good luck.

At the moment I consider this question closed .

[Manolis]

Torsten I did not create any function named "plot" at all. In fact I did not create any function.

In fact it is my second day at Matlab-land.

Thanks a lot

[Andreas Goser]

If I understand you correctly, you are under the impression you cannot contact technical support as your are on a trial? Why is that?

[Manolis]

II thought it is like that. Anyway thanks for the support.

Answer 1

[Manolis]

Yes ! It is working -at least so far.

Instead of typing "matlab" at the terminal I typed "matlab -softwareopengl" and lastly I saw the line. It is hint from "https://uk.mathworks.com/help/releases/R2024b/matlab/creating_plots/resolving-low-level-graphics-issues.html" .

Have a nice day everybody and thanks.
