Graph visualization adding white to my nodes. How to solve it?

5 views (last 30 days)
Hello everyone,
I am having a problem with my graph visualization. In particular, my nodes are not being presented only in the colour selected, but they also have some white parts. In addition, these white parts are not "static", with every step of the loop (which changes the colour of one node at a time) there is a change in which part of each node is drawn in white.
I am posting an image of what I’m seeing:
I have already tried the same code on a different computer and the problem doesn’t persist. So I am guessing there is some setting I can adjust to solve this.
Thanks in advance for your collaboration!

I have changed the marker symbol and the problem disapears, so there must be something special with circles.

I'd assume this problem will also happen with other graphics elements. Could you try the following code and let me know if you're seeing the same issue there?
scatter(randn(10,1), randn(10,1), 'o', 'MarkerFaceColor', 'b', 'MarkerEdgeColor', 'b')

Can you check if there's an update available for your graphics driver?
If not, did this behavior suddenly start appearing (after a graphics driver update or a Windows update?) If it occurred after a graphics driver update, consider reverting that update to determine if it's a bug in the driver.

Hello,
My grahics driver is updated.
About your second question. I had an older version of MATLAB and got the 2017b version because the function I am using does not work on the one I had. So I have not done this type of graphs before.

This is a visual artifact I assume. Try add Edge Color to your nodes. It could help.
