Using a tuple to designate a single colour in a plot command, like this:

plot(range(10), c=(0.5, 0.5, 0.5))

and then clicking on the "Edit curves line and axes parameter" button raises this TypeError:

Traceback (most recent call last):

This is very related to #917.

I just discovered that this:

plot(range(10), range(10), 'k', marker='o', ms=3)

also raises the exact same traceback and error:

However, if I use

plot(range(10), range(10), 'k-o', ms=3)

instead, I get the exact same plot, and no error when I click on the "edit curve line and axes parameters button"

Confirmed with v1.2.x. I think this limitation has always been present.

Thanks! That fixed the TypeError in both cases in the first post. But when I do this:

plot(range(10), c=(0.5, 0.5, 0.5))

and then click on the "Edit curves line and axes parameter" button, the line and marker colours show up as my default black instead of grey, so the dialog isn't being updated properly. Hitting Apply or OK changes them to black, without me actually changing anything in the dialog. Not a big deal though.
