matplotlib-users Mailing List for matplotlib

Maybe workflow may not be the appropriate term. Essentially, when I want
to plot something using matplotlib, I find myself having to look up the api
docs or examples online because quite frankly, matplotlib's syntax is very
hard to remember. I use ipython and use tab browsing, help(), dir(), etc,
and that seem to help to some extent. I absolutely love matplotlib, but
when I want to put a chart up quickly, matplotlib is just a "hassle"
depending on what chart you want to create. I do expect this since
plotting with matplotlib, you are essentially creating a chart
"programmatically", instead of GUI interface environment. But still, I
feel like an improvement could still be made in making charts simpler with
matplotlib.
While surfing the web, I ran into this module called Canvas:
https://github.com/mdipierro/canvas
Canvas appears to be what I am after or what I wish matplotlib's future
syntax should strive for.
Currently, I store my matplotlib chart source code in folders with the file
name describing what chart it creates (for example, "box_plot.py" or
"control_chart.py", etc.) and use them as "cheat sheets" when I need to
make a chart. I am curious what other matplotlib users do? Otherwise, I
do find myself sometimes just creating the chart in Excel as a 1st option,
and make charts in matplotlib if it is something Excel can't handle.
Thanks in advance,
Daniel

For me your PDF is OK, nothing "broken". I get exactly the same (mpl 
1.1.0, on Windows XP, Python 2.7).
Your problem has probably nothing to do with matplotlib...

No extra "stuff" in the png and pdf plots in my case (changed the hash-bang line):
Mac 10.7.4 w/ python and matplotlib from (not too recent) Fink:
 i python27 1:2.7.2-5 Interpreted, object-oriented language
 i python27-shlibs 1:2.7.2-5 Interpreted, object-oriented language
 i matplotlib-base 1.0.2-1 Plot data on map projections with matplotlib
 i matplotlib-py27 1.1.0-2 Pure python 2D plotting with a Matlab syntax

Hey everybody,
I am trying to create a simple plot with a dotted line. However,
depending on the export format I use, I get random markers on the
line. This effect appears for pdf but not for png. When I use eps and
convert the eps file to pdf I also receive the random markers.
I use the following script to generate the plot. The resulting graph
on my system is attached to this mail.
#!/usr/bin/env python
import numpy as np
a = np.linspace(0.,10.,100)
b = np.sqrt(a)
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111)
fig.add_subplot(ax)
ax.plot(a, b, linestyle = ':', color = 'k', linewidth = 3)
fig.savefig('broken.pdf')
My system is:
Linux 3.2.0-24-generic #39-Ubuntu SMP Mon May 21 16:52:17 UTC 2012
x86_64 x86_64 x86_64 GNU/Linux
I am using matplotlib version '1.1.0'.
Any help is greatly appreciated.
Benjamin
