Plots appear as giant blocks rather than actual waveforms

6 views (last 30 days)
Hi everyone,
I am trying to be able to display my waveforms in Matlab. I have tried "linkaxes" but I just continue having a giant blue block (see attached pictures) for all my plots. I think is due to me having used a high sampling frequency (high No. of points) but I need these amount of points since I am using FFT.
I honestly don't know how to fix my graphs. Please any help would be greatly appreciated.
P.S. I have thought of setting axis limits manually but I would like to know if there is a function out there which can scale my graphs atomatically for me.

The waveforms are there. The problem is that they are very densely packed in those images, so they appear as blue blocks.
Use the xlim function to ‘zoom in’ on a much smaller region of the independent variable to see them more distinctly.
