If pzmap had worked properly then the OP would not have tried the hold command.

Yes, mike, I think that covers it.

Confirmed all of these observations on the development branch and the latest control package.

So the first issue seems to be that the 'hold' state should not keep the default color at blue, but should continue to rotate across the standard color order for subsequent calls.

The second issue seems to be that user styles passed in to the function should not be allowed to override the internal choices of ('linestyle', 'none') and ('marker', 'x' or 'o').

Does that capture everything accurately and completely? Thanks.

best to keep everything here, lest nabble be unavailable

pzmap [control package 3.2.0] appears to have some issues with plot formatting. confirmed non-compability with Matlab 2019a.

Issuing the following commands produces an image with incorrect color and legend (see pkmap.png and pkmap_matlab.png):

pzmap(tf([1 9],[1 2 2 4 5]))

hold on

pzmap(tf([1 8],[1 2 2 4 5]))

the following produces a plot with a red line replacing the plot instead of pole-zero marks (see pzmap1.png and pzmap1_matlab.png:

pzmap(tf([1 8],[1 2 2 4 5]))
hold on
pzmap(tf([1 9],[1 2 2 4 5]),'r')

Last, the following should result in blue x and o, but it just makes them all x's (see pkmap2.png and pkmap2_matlab.png):

pzmap(tf([1 9],[1 2 2 4 5]),'bx')

Please state the bug and show examples here, a bug report can't depend on an external link. I saw on the mailing list that this has something to do with line styles, please be explicit about that here.
