## [Matplotlib-users] plotting two lists

 [Matplotlib-users] plotting two lists From: Jan Rienyer Gadil - 2005-03-31 07:32:26 i'd just like to ask how to make a simple graph of two lists??? i've seen this in the tutorials... a = self.fig.add_subplot(111) t = numpy.arange(0.0,3.0,0.01) s = numpy.sin(2*numpy.pi*t) c = numpy.cos(2*numpy.pi*t) a.plot(t,s) a.plot(t,c) ============= so if i am to plot two lists say listY[] and listX[], i should do this: a.plot(listY, listX) ============= please, any help will be greatly appreciated!

You can use python's introspection capability (help, dir, type) to ask an object about itself. You can insert print statements directly into your code print dir(self.axes) # see below the results of dir(self.axes) and look for methods that have the right names. Or you can keep a python shell open and use the python help system. If for example, at the shell you do help(self.axes), you'll find Help on instance of Subplot: So self.axes is a Subplot instance. You can then import the Subplot class and get much richer help by doing >>> from matplotlib.axes import Subplot >>> help(Subplot)=20=20 If you don't like working from the shell, head on over to the class docs at http://matplotlib.sourceforge.net/classdocs.html and click on the "axes" link and near the top of your screen you'll seen a link that reads Subplot(SubplotBase, Axes) That means the subplot class is derived from SubplotBase and Axes. Click on Subplot, and read through the available methods. If you get impatient, search the web page for "xlabel" Good luck!

 [Matplotlib-users] missing clabel? From: Mark Engelhardt - 2005-04-28 08:43:41 Hi, I am trying to construct coloured contour maps, but when I do: from pylab import * clabel is not there. Was this removed? The docs suggest that clabel is part of the pylab module. thanks, Mark
 Re: [Matplotlib-users] missing clabel? From: Mark Engelhardt - 2005-04-28 09:03:15 Sorry - problem solved. I was 0.01 versions behind on the computer I was using.

Hi Jan, axes.xlabel doesnt exist. What you are looking for is self.axes.set_xlabel(parent.Xaxis.GetStringSelection()) self.axes.set_ylabel(parent.Xaxis.GetStringSelection()) The Matplotlib devs have put a lot of effort into documenting the project. In situations like this, I often end up relying on the python interactive interpreter to find the method I am looking for: from pylab import * fig = figure() ax = fig.add_subplot(111) dir(ax) or you could add a line in your own code: self.figure = Figure() self.axes = self.figure.add_subplot(111) self.axes.plot(parent.listX,parent.listY, 'bo') print dir(self.axes) both would give you a list of available methods. Hope this helps, Darren
