Error with py_color when using Color Gradient with PyPlots

[mbotkinl]

When I specify the series color as a Color Gradient, I get an error

using Plots; pyplot()
plot(rand(20,5), seriescolor= :RdYlBu)

Error showing value of type Plots.Plot{Plots.PyPlotBackend}:
ERROR: MethodError: no method matching py_color(::ColorGradient, ::Nothing)

This same syntax work for the GR backend of Plots. I am using julia 1.0.1, Plots 0.21.0 and PyPlot 2.6.3

On my computer that code snippet segfaults :-O

On GR this does not really work either, you get a plot with only red lines. I think what you actually want to do is

plot(rand(20, 5), palette = :RdYlBu)

right?

[daschw]

Still, this should not produce an error like that.

[mbotkinl]

Yes, what i really want to do is something like:

plot(rand(20,5),palette=:RdYlBu,line_z=(1:5)')

However, plot(rand(20,5),seriescolor=:RdYlBu,line_z=(1:5)') works for GR but not pyplot. Not sure if that is the intended behavior or not but figured I would submit the error anyways.

Ah now I see, with line_z seriescolor = :RdYlBu makes sense, I guess. Thanks a lot for reporting!

seems to be fixed. Can't reproduce anymore.
