Simulink data inspector corrupting signal display depending on the zoom.

Hi all, title says it all. For some reason simulink data inspector isnt playing nice and corrupting the display as shown below.

The errors get fixed once I zoom in to a certian level so know the signal iself isnt corrupted. Are there any commands to reset / troubleshoot this issue?

Running Ubuntu 20.04.6 LTS with MATLAB version 2018b, simulink v9.2. I would love to update to the latest version and for this to be fixed but I am not allowed/able to update.

Hi Dean,

While the Simulink Data Inspector is fully zoomed out, it displays values that are rounded.  This might be the reason that you are seeing values that are different form the ones that you are expecting.  As you start to zoom in with the Simulink Data Inspector, you will start to see that the values become more accurate.

That makes sense although I thought it would be more consistent rather than select samples getting rounded to zero. The image only shows some samples getting rounded any only from the complex part of the signal.
