[Matplotlib-users] Getting started with bar charts
The matplotlib philosophy is one of "make easy things easy" - which I totally agree with. I am a new user of matplotlib; and a relatively new Python programmer. I am trying to produce some bar charts for a colleague, in an attempt to show how easy it is to do this with Python/matplotlib (as opposed to the old Excel/cut-n-paste approach!). I think I have got the basics OK (two subplots), but I am struggling with what *I* think should be trivial tasks - such as setting line widths, font sizes, bar colours etc. The examples do not really seem to deal with these issues, and in fact the homepage implies these are for a "power user", which I find strange because these are some of the first things most users want to "fiddle" with! What I have done as a temporary fix is alter all the settings in the matplotprc file; but this is not ideal as these settings affect *all* charts. It appears the manual (which I assume might be able to help me) is not "downloadable". The link : http://matplotlib.sourceforge.net/users_guide_0.87.1.pdf results in a 2.41MB PDF file, which Acrobat Reader reports is "damaged". (I also noticed when running the download, that the download manager seemed to be expecting a 4.5MB file?) The example: http://www.scipy.org/Cookbook/Matplotlib/BarCharts shows how to setup labels for a bar chart - but it would be great if there was a line-by-line explanation of what each step means; its not very clear! The last point of "mystery" to me is that of "plot" vs "subplot" vs "bar" - are these all essentially the same family of object, with some differences in their capabilities - or vastly different beasts? Any help with these "newbie" issues would be appreciated! Thanks Derek -- This message is subject to the CSIR's copyright, terms and conditions and e-mail legal notice.

Perhaps it should be distributed using the same sf.net download mechanism as the software itself? Try using some software that knows how to resume interrupted downloads.

Re: [Matplotlib-users] Getting started with bar charts
Jouni I have now loaded and tried to use iPython. In some cases the xyz? command gives useful output - in others, not. So, if I have ax = subplot(111) Then ax? returns a number of get_ & set_ functions that are available. So far, so good. But, if I try something like : In [9]: ax.set_xlim()? I get Object `ax.set_xlim()` not found. So, I cannot find out more about what setxlim() is meant to do, or how it works? What I did do was go and look at the class documentation on-line, and this info is available there. You suggested: "The list you want is precisely the output of the getp command." But for the getp? , I get: Type: function Base Class: String Form: Namespace: Interactive File: c:\python24\lib\site-packages\matplotlib\artist.py Definition: getp(o, *args) Docstring: Return the value of handle property s h is an instance of a class, eg a Line2D or an Axes or Text. if s is 'somename', this function returns o.get_somename() getp can be used to query all the gettable properties with getp(o) Many properties have aliases for shorter typing, eg 'lw' is an alias for 'linewidth'. In the output, aliases and full property names will be listed as property or alias = value eg linewidth or lw = 2 Example: plot(t,s) set(gca(), 'xlim', [0,10]) # set the x axis limits or plot(t,s) a = gca() a.set_xlim([0,10]) # does the same (and gca? returns something along the same lines) Which does *not* intuitively lead me to something like: xticklines = getp(gca(), 'xticklines') for example?? So - the question is how to get to find the items I need to set - amongst others, I am still looking for something to size the tick marks; setting those on the bottom X-axis to a specific size, while disabling those on the top X-axis. The matplotlabprc file has a clearly labelled line that addresses part of this: xtick.major.size : 2 # major tick size in points but of course I would like to do this in code. I am sort of guessing this has something to do with the Tick class: http://matplotlib.sourceforge.net/matplotlib.axis.html#Tick but I cannot seem to work with Tick() ?? In addition, I cannot seem to see why some things work one way and others - seemingly in the "same family" - do not. For example: xticklabels = lab.getp(lab.gca(), 'xticklabels') works just fine, and allows you set the font size, color etc for the tick labels, whereas there is no: lab.getp(lab.gca(), 'ylabel') even though both appear to be dealing with a similar "thing" (a Text object)?? *** I guess that, overall, I have been expecting matplotlib to have a simple "dot" notation throughout - xaxis.xtick.major.size = 2 as this type of notation is readily easy to grasp and use, but this preconception is blocking my grasp of how to use the module 'as is'. Again, apologies for the repetitive questions, and thanks for patience in answering them.

[Matplotlib-users] Using toolbars modes considered safe ?
I am using the Navigation toolbars mode and I wonder if I should the attribute or if it can change in a future release ? The attribute I am talking about is defined in backend_bases.py in NavigationToolbar2 in the __init__() method: self.mode = '' # a mode string for the status bar The strings saved on the panning and zoom mode are kinda unconventional: self.mode = 'pan/zoom mode' or self.mode = 'Zoom to rect mode' Having the zoom word in both strings can be confusing, moreover they should start either with a lower case or upper case. Can't they just be "zoom" or "pan" ? Having just one word as a mode will remove confusion and make them easier to test when you are adding modes to the toolbar ... Just a suggestion.

Hi, thanks for the link to the screen capture tool. I've been looking for something like it (similar to MS OneNote sort of), but haven't found one. The figure window by default has a button that allows you to save the image. As for your increased precision, I recently discovered Python's decimal package, http://www.python.org/dev/peps/pep-0327/ It allows you to specify arbitrary precision, and doesn't use hardware-based floating point representation. As far as I can tell, it manipulates digits like you would do it on paper, keeping as many digits as you tell it. Good luck!

[Matplotlib-users] 3d Plotting
I understand that 3D plotting is not fully working yet, but I have a question that might be answerable anyway. I can get a nice looking 3D plot of my data using surf = ax3d.plot_surface(x, y, z) but I can't control the colors used in the plot. I can do a surf.set_array(ColorArray) and the contents of the array (ColorArray) will be translated into colors on the plot somehow, but the translation appears to be arbitrary. Does anyone know how the translation is done, so that I can assign a certain color to a certain part of the plot? Thanks, Rich. - Using Tomcat but need to do more?

The colors come from the current colormap. You can go all out and make your own colormap and color based on index using your map. I don't know how to do that off the top of my head though.

You need to do ax.set_xlim? without the parentheses.

I meant the output of the actual getp command, not its help text. E.g.
In [4]:recs=bar([1,2,3],[4,5,6])
In [5]:getp(recs)
alpha = 1.0
animated = False
...
y = 0.0
zorder = 1
gives you the list of properties settable with setp. Similarly
getp(gca()) gives you a long list of properties, including xticklines.

I guess it isn't very obvious how to do this with setp. It is the
markersize property (which has the abbreviation ms):
In [25]:setp(getp(gca(), 'xticklines'), 'ms', 10)
Note that here getp returns a list of objects, and setp sets the
property on every object in the list.
But if you already know what something is called in the matplotlibrc
file, you can set it programmatically:
In [49]:rc('xtick.major', size=5, pad=20)
The rc settings do not affect existing images, so you have to make a
new plot before you see the effect:
In [50]:figure(); bar([1,2,3],[4,5,6])
> I guess that, overall, I have been expecting matplotlib to

> xaxis.xtick.major.size = 2
The getp/setp methods are part of matplotlib's pylab interface, which
is designed to reproduce Matlab's "handle graphics". There is also an
OO interface, which looks like this (this is the agg_oo.py example
from the examples subdirectory):
fig = Figure()
canvas = FigureCanvas(fig)
ax = fig.add_subplot(111)
ax.plot([1,2,3])
ax.set_title('hi mom')
ax.grid(True)
ax.set_xlabel('time')
ax.set_ylabel('volts')
canvas.print_figure('test')
I seem to recall some discussion about making it more Pythonic, e.g.
allowing you to do
ax.title = 'hi mom'
ax.xlabel = 'time'
but I don't know whether it is a high priority for any of the
developers.
