How do I improve the quality of my plots?

I'm adding figures to a matlab report with the following code:

import mlreportgen.report.*

fig = [f1, f2, f3]

ch = Chapter('Name of the chapter');
for i = 1:3
  Fig = mlreportgen.report.Figure(fig(i));
  add(ch,Fig);
end 

Report generator creates a pdf file with the figures. The problem is that for some plots (like the second one), the quality is really poor.

Does anyone have an idea why this is happening?

Thank you!

Can you check by setting the Figure reporter's SnapshotFormat to be SVG or PDF, if that helps

Fig = mlreportgen.report.Figure(fig(i));
Fig.SnapshotFormat = "svg";
% Fig.SnapshotFormat = "pdf";
