I am trying to analyze a DC motor but in one of my graphs I get circles on all my data points (sample time 0.001)
The only graph where this happens is after the multiplication of the voltage with a discrete transfer function. (see pictures 1, 2 and 3)
Even weirder is the fact that after a saturation the circles apear gone (see picture 4)
Does anyboy have an idea what causes the circles to appear because i don't see how the are created and they don't seem to influence the rest of my simulation

You have enabled markers in your scope window. You can change line and marker styles by going to the 'View' and then 'Style...' button in the scope window. If you want to disable the Markers, select 'none'.
This is purely a visual option and has no effect on your simulation. For your reference, when enabling markers, the scope window will use one marker on each data sample. This can be helpful when analysing sample-by-sample behaviour in discrete simulation models.

I had the same issue, however it was activated automatically and had to disable it manually.
I think it's because the input data was not "interpret vector as 1-D" but I am not sure.

I think the actual question was how to stop Simulink from defaulting to this mode when the scope measurement if flat or null. Every time you disconnect a signal or pass in a constant signal you have to manually go in and change the scope setting even though you never manually set it in the first place. The happens literally every time you hit 'Run'. This is a massive waste of time, especially while attempting to debug a model.

Hi,
if I understood your question correctly, the circles you are referring are not circles but the data points from your simulation results. if you'd wish to remove them and use just a bold line, then use scope parameters (icon is like a gear).
Good luck.
