How can I rectify the issue of figure not displaying curve the right way?

The displayed figure for validating feedforward network i trained on ubuntu using R2025a is showing random dashes instead of a solid curve, any approach to solving this pls?

I am not exactly certain what the problem is (not enough information), however increasing the LineWidth could be a solution, folloowing up on this post.

I tried that out but it still persist. I was thinking, could they be any package I'm supposed to install on ubuntu, needed to display the figure in the right?

It would be helpful to have your code. (and data files if necessary) I run Ubuntu 24.04 and I have never seen the problem you illustrate.

Since the display itself is apparently not the problem, look at your data, specifically using something like this:

nrnans_x = nnz(isnan(YourXdata))

nrnans_y = nnz(isnan(YourYdata))

The only thing I can think of is that the data have NaN values in them, and NaN values do not plot. (NaN values are 0/0, Inf/Inf, or NaN values in earlier calculations or data.)
