nyquistplot strange behaviour

[albheim]

Saw that the nyquist plot in the updated ControlExamplePlots looked a bit odd. It writes "u(1) to y(1)" on all four subplots, and the xrange does not seem to scale. Remade locally and can confirm this is the same plot I get.

Had a quick look at the code and to me it seems like neither of these should happen.

Plots has become a bit buggy with default keyword arguments in plot recipes lately. It sometimes helps to move the keyword definition slightly within the recipe. I'll try to have a look tomorrow, can see of we can come up with a nice example to open an issue on the plots repo because it's quite annoying
