Thread: [Matplotlib-users] Equivalent to Gnuplot histeps style

I am a recent switcher to matplotlib from gnuplot so please forgive me
if I post often.

I am currently looking to see if there is a similar matplotlib
plotting style like gnuplots "histeps".  An example is:

http://gnuplot.sourceforge.net/demo_4.2/random.4.png

As I searched through the email list archives, it seemed like John was
looking at adding "steps" as a linestyle to matplotlib.  The email is
a few years old

http://sourceforge.net/mailarchive/message.php?msg_id=4158CE19.3060601%40gemini.edu


I was wondering if anything came from this or if I need to figure out
something on my own.

Thanks in advance.

Jeremy

Jeremy,

I ran across the answer to this last week while searching the list for 
info on datestr2num (both subjects happened to come up in the same 
exchange).

plot(x, y, linestyle='*steps*')

Well that's great!  (I should have at least tried making such a plot
before posting.  Sorry.)  How come I couldn't find it in the
documentation?  I can't find anything about available linestyles.  Am
I looking the wrong location?  I am looking at users_guide_0.9.0.pdf

Thanks again,
Jeremy

The user's guide tends to lag.  To find the latest features, look at the 
CHANGELOG, the examples, and the docstrings.  Ipython is a big help for 
looking at docstrings and trying things out.  Are you familiar with it?

 am familiar with IPython and use it all the time as a replacement
for the standard Python interpreter.  I don't always use the extra
features it offers.  I just did

help pylab.plot

and there it was, what the available linestyles.  Again lesson
learned, read the (available) documentation before asking the
questions.  It is sometimes confusing where to go for the
documentation.

Thanks,
Jeremy

Even easier:

pylab.plot?

And for more detail (but mostly useful for matplotlib modules and 
functions rather than for their pylab wrappers), use two question marks 
to view the source code.

To see available functions or attributes, use tab completion.

Ooh, very nice.  I'll try to incorporate those commands into my daily
repertoire.
