Actually, I discovered today that this is possible. You can use step()
to achieve what you want:

Not at all of course. Glad this might be of some help for matplolib.

Thanks, just forgot about the license. It will be the same as the scipy lecture notes which is a

Would that be ok or is a BSD one more suited ?

Thank you all, I will try to correct that.
I developed it in full screen mode and did not paid attention to the layout.

Very nice.  I'm thinking of some ideas to revamp the 
documentation/website, and one thing I would like to do is to link to 
some of these external resources.  Do you have any objections to me 
linking to this?

This is really beautifully presented. It would be great if some, or all of
this could be integrated into the main Matplotlib site. Someone emailed the
list not too long suggesting that the user guide was geared more toward
developers. This tutorial would definitely fill the gap.

If nothing else, I would love to see the "Other types of plots" and "Quick
Reference" sections as pages on the main site with links to them on the
main navigation bar.

Nice work!

Same on epiphany 3.4.2 (webkit 1.8.1)

I see this behaviour too, on Chrome, version 20.0.1132.57.

Tutorial  looks nice, though :)

Nice work.  I haven't read through all of it yet, but I did notice a layout
issue in firefox (using 10.0.4).  Many of the code snippets are being
placed on top of the example image.

What is the license for this tutorial?  You should also place some
copyright info at the bottom as well.

Hi all,


I've just finished a new introductory tutorial for incoming Euroscipy 2012. You can find it here:

http://www.loria.fr/~rougier/teaching/matplotlib/


It is based on Mike Müller tutorial from scipy lecture notes (http://scipy-lectures.github.com/intro/matplotlib/matplotlib.html)

Sources are available from: https://github.com/rougier/scipy-lecture-notes/tree/euroscipy-2012


If you've any comments or see errors...

I'm not sure I understand what you're asking. Are you asking how to make
a stairplot, or are you asking how to make *multiple* plots on one set
of axes?

If your question is the former, matplotlib does not currently have a
stairplot implementation, but it wouldn't be hard to use the usual
plot() function to achieve the desired effect:

Before:

x = arange(0, 10, 1)
y = x * (10.0 - x)
plot(x, y)

After:

x = arange(0, 10, 1)
x_m = x - 0.5 # left-hand midpoints
x_p = x + 0.5 # right-hand midpoints
y = x * (10.0 - x)
x_all = dstack((x_m, x, x_p)).flatten()
y_all = dstack((y, y, y)).flatten()
plot(x_all, y_all)

If your question is the latter, you can toggle the hold state just by
calling

hold()

Hope this helps.

Dear All,

I want to stairs plot (similar in matlab) matplotlib
First i want for i data-set then multiple data-set super impose on that.
I attach the figure it's showing velocity-depth stairs plots for
superimpose (like hold on in matlab)
large data-set.
can anybody tell me how to plot that.

see the figure

Thank you
