bug?

Hello, I have a problem with the svn version of matplotlib. I don't know when
this problem appeared but it was working before.

so the next script gave me an error message:

import pylab

p = pylab.plot([1,2],[2,3],'o')
pylab.setp(p,markerfacecolor=(120,120,120),markersize=5,markeredgewidth=1.,zorder=50)

pylab.show()

the main error message is:

ValueError: to_rgb: Invalid rgb arg "(10.0, 10.0, 10.0)"
to_rgb: Invalid rgb arg "(10.0, 10.0, 10.0)"

but I don't understand why.

An rgb colorspec in matplotlib must be a sequence of three numbers between zero and one, so the problem is that you are indeed giving an invalid rgb arg.

I think perhaps you grabbed an error message from a different instance of this error; when I try it, I get an error message that correctly gives the invalid arg that was supplied:

ValueError: to_rgb: Invalid rgb arg "(120, 120, 120)"
to_rgb: Invalid rgb arg "(120, 120, 120)"

Some change have been introduce in matplotlib? Because I used this sequence
before and it was working. I'm a little bit surprise by the fact that the rgb
sequence must be three numbers between 0 and 1. Generally rgb sequence are
between 0 and 255, aren't they?

And so my sequence is correct in this definition but yes false in the actual
matplotlib definition but in this case an explicit error message must be
given to tell that RGB color doesn't respect the general convention and must
be between 0 and 1

Regards,

N.
