Problem with legend command

I have a problem with the legend. When I use the legend command, you don't see the box and colored lines on the plot. You only see the writings. I can't fix it, does anyone know what I can do?

Answer 1

[RITAM BASU]

for turning on the box, try:

legend('boxon')

I tried but it doesn't work

[Amin Damrah]

this is my problem.

This is a known problem with certain AMD graphics drivers, although it was fixed a while ago.

Go to the GeForce Experience website. It has a downloadable app that will automatically find your videocard and download the correct current driver for it.

I try and let you know if it works

[Star Strider]

If you have an AMD graphics card and haven’t updated the drivers in a few years, the update should colve it.

[Amin Damrah]

I think this doesn't solve the Matlab Legneda problem.

[Star Strider]

It you have an AMD graphics card with a driver that has not been updated in a few years, it should solve it.

If you have updated the driver and are still getting the problem, please post your code and any necesary data needed to run it.

[Amin Damrah]

I gave a simple example.

[Amin Damrah]

y1 = rand(3);
ax1 = nexttile; 
plot(y1)
legend(ax1,{'Line 1','Line 2','Line 3'})

[Star Strider]

It works correctly here —

y1 = rand(3);
ax1 = nexttile; 
plot(y1)
legend(ax1,{'Line 1','Line 2','Line 3'})

Do you have an AMD graphics card? If so, did you upgrade to the latest driver?

Also, this should work —

clf

y1 = rand(3);
opengl('software')                                      % Will Be Removed In An Upsoming Release, Still Works
ax1 = nexttile; 
plot(y1)
legend(ax1,{'Line 1','Line 2','Line 3'})

If the opengl call solves the problem, and you have an AMD graphics card, the driver is the problem. Update it.

See the documentation on Resolving Low-Level Graphics Issues and rendererinfo.

opengl('software')

with this, it is correct. Thank you.

That confirms that you still need to update the driver. Tha AMD software that I linked to makes that straightforward.
