 [Matplotlib-users] subplot problems using comma notation From: Josh Lifton - 2006-11-17 04:46:02 ```I've been having problems using the subplot command's comma notation for describing how many plots to use (e.g. subplot(2,1,1) instead of subplot(211)). Using the comma notation, all plots are overlaid in the first position and remaining positions are blank but sized correctly as if there should be a plots there. Here's an example demonstrating this problem. This code is a minimally modified version of that given in the online tutorial. ################################################## from pylab import * def f(t): s1 = cos(2*pi*t) e1 = exp(-t) return multiply(s1,e1) t1 = arange(0.0, 5.0, 0.1) t2 = arange(0.0, 5.0, 0.02) figure(1) subplot(2,1,1) plot(t1, f(t1), 'bo', t2, f(t2), 'k') subplot(2,1,2) plot(t2, cos(2*pi*t2), 'r--') show() ################################################## I will probably end up using the axes command, but it would be nice to know how to resolve this issue with subplot. I'm using Python 2.4 on Ubuntu 6.06 Thanks, Josh ```

 Re: [Matplotlib-users] subplot problems using comma notation From: Josh Lifton - 2006-11-17 06:03:49 ```Thanks for confirming that it works on another system. As I'm currently using 0.82.5, I suspect upgrading to 0.87.5 (apparently the latest available through official Ubuntu repositories in the newest distribution) will solve the problem. I'll report back once I do this. Any Ubuntu users out there have a similar experience?

Where did you find matplotlib 0.87-5 though? It's not in the repositories as far as I can tell. I use synaptic for upgrading.

 Re: [Matplotlib-users] subplot problems using comma notation From: Josh Lifton - 2006-11-17 13:26:29 ```Unfortunately, 0.87-5 is only available in the 6.10 (Edgy) repositories, so we'll have to upgrade to 6.10, request that matplotlib be backported to 6.06, or find a non-Ubuntu repository from which to install the latest matplotlib package. I plan on upgrading sometime soon, so I'll wait for that.

 Re: [Matplotlib-users] subplot problems using comma notation From: Eric Firing - 2006-11-17 17:28:53 ```I would encourage anyone running linux to simply build matplotlib from the latest release tarball. It's easy. You may need to install some devel packages first, but once you have stumbled over the missing bits and installed them, then forever after you can very easily update to the latest version whenever there is a release. Matplotlib changes fast enough that this can be quite a help.

That is probably because you installed a matplotlib compiled against newer libraries (e.g. numpy and/or Numeric and/or numarray) than you have installed on your machine (although I think package dependencies *should have* prevented this). If you build matplotlib from the tarball this will not occur--it will be compiled against the libraries that are on your machine. As I said before, you will only need to install some devel packages from your present distribution so that you will have the corresponding headers. Eric ```
