hi all,
i'm getting very strange behavior from the matplotlib 'plot' function when
attempting to plot multiple lines. i have a series of x, y data points that
are being generated in a loop and i want to simply plot each of them on the
same plot. my code is:
import matplotlib
matplotlib.use('PDF')
Hi Jon,
To clarify, I think you need to read Christoph Gohlke original message
(7/7/2009) to me to put my response into context:

Hello,
I'm writing a script that removes data from plots by looping over
axes.get_lines(), removing data, then using axes.set_lines(). It works quite
well, but when it's a plot with error bars, the vertical part of the error
bar is not disappearing.
I'm assuming the vertical part is a vline or som

Hi all,
I'm a newbie, I'm trying to plot a line with an arrow
(arrow in the middle and another with an arrow at
the end) with the following points: [1, 2] and [5, 2]
Could anyone please help me with the code?
Thanks.

Question is however, are you using the GTK backend?
ie
from matplotlib.backends.backend_gtkagg import FigureCanvasGTKAgg as
FigureCanvas
from matplotlib.backends.backend_gtkagg import NavigationToolbar2GTKAgg as
NavigationToolbar
backend_gtkagg then imports matplotlib.backends._gtkagg
For matplot
Please post a standalone example that reproduces your problem.
I tried your example with some junk data but no such exception is raised.
However, there has been a report of a similar ordinal value problem
which I think is not fixed yet, but that problem only occurs when two
and more axes are share
Not too long ago, I posted an example of this to the list. The code
near the bottom of that thread is a little more general than the one
at the top and shows, three different ways to cycle through the colors
of a colormap.
Hope that helps,
-Tony

Hi all,
i would like to set the colors of the lines i plot (using the plot function)
to go from red to blue, in evenly spaced interval. that is, imagine a color
map from red to green, where i plot n-many lines, each receiving a color
from this color map, starting at the red end and going to green.
I am trying to plot some historical trend data, where x is a date and
y is a percentage.
When I try to insert a horizontal line with ax1.axhline(y=80,
linewidth=1, color='r'), matplotlib breaks, with an error "
ValueError: ordinal must be >= 1".
The Traceback most recent call is, File
"/usr/lib6
