And if you have mutually prime numbers of colors,
linestyles, widths, you can automatically generate
more distinct lines than I can distinguish... If there's any
wxcuse for treating them as a series, I replot
when I know how many I have, and space the
colors through a colorbar.

By the way, I found that the following generator expression made things
easy:
def styles():
return ( {'c' : color, 'ls' : style, 'lw' : width} for color, style,
width in itertools.product(colors, linestyles, linewidths))
then you can do something like
for result, style in zip(results, styles
Thanks!

Hi John,
Here is a simple way to do it.
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
ax = fig.add_subplot(111)
colors = ('red','green','blue','yellow','orange')
linestyles = ('-','--',':')
linewidths = (0.5,2)
y = np.random.randn(100,30)
x = range(y.shape[0])
i = 0

How sure are you that the floating point num
Here are a couple of functions you might try, with a few colors and line
styles I use:
import itertools
from pylab import *
COLORS = ['#990033', '#FF', '#00FF00', '#F79E00',
'#ff00ff', '#0080FF', '#FF', '#2D0668',
'#2EB42E', '#ff6633', '#8000ff', '#33',

More precise, the string 'None' translates to fully transparent

Hello,
I have a plot with lots of curves on it (say 30), and I would like to have
some way of distinguishing the curves from each other. Just plotting them
works well for a few curves because they come out as different colors unless
you specify otherwise, but if you do too many you start getting r

I got a problem with backend in matplotlib.
I used ipython for launching the codes and the backend of
matplotlib is GTKAgg. I have a code.py with a for loop for processing data,

What I use to create animations is plainly:

plt.clf()

where filecode is the name, digits an int and format usually .png.
clf() is important in order to prevent memory leaks, because otherwise

Hi list,
I am using animated artists to generate an animation, where I save each step
in the anmantion as a png using the savefig method of the figure instance
after drawing the animated artists on a cached background and after
fig.canvas.blit.
What I see on screen are the updated animated artist
