[Matplotlib-users] bug?

[<hu...@ya...>]

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=
=20
before and it was working. I'm a little bit surprise by the fact that the r=
gb=20
sequence must be three numbers between 0 and 1. Generally rgb sequence are=
=20
between 0 and 255, aren't they?


http://homepage.mac.com/jakesan/DHP/page0/page3/page3.html

And so my sequence is correct in this definition but yes false in the actua=
l=20
matplotlib definition but in this case an explicit error message must be=20
given to tell that RGB color doesn't respect the general convention and mus=
t=20
be between 0 and 1=20

N.
