[Matplotlib-users] Matplotlib Windows binaries - problem
Hi, I'm trying to install matplotlib on a windows machine at work to try and demonstrate its usefulness. I have Python 2.6 installed and managed to use the numpy binary install without admin priviledges. The matplotlib binary installer, however, requires admin priviledges, and I don't understand why - is an alternative installer available, because otherwise, I'll have to drop matplotlib and Python for somethign else, as IT will take a month or two to install it for me. I know I could build it myself, but the same restrictions are causing problems getting the pre-requisites installed!

[Matplotlib-users] Plotting with custom symbols
Hi, I've looked through the documentation, and see that it's possible to plot a variety of symbols, including some customization, but what I'd really like to do is use a text character as the point marker. The only way I can think of doing this right now is to annotate the point (with zero offset) with the text in question, and somehow hide the actual point itself (is that even possible?). Is there something easier/more obvious that I'm missing? Thanks!

[Matplotlib-users] Point-specific colors with scatter
Hi there, I've got 4 time series that live in a 2-d space (imagine points at (1,1), (1,2),(2,1), and (2,2) that drift a little over time), and I'm using scatter() to show them. How can I plot so that each of the groups of points has the same colour? I've checked the docs and examples and can't seem to find quite what I'm looking for. A sample script or indication of where to look in the docs would be appreciated. Many thanks!

Re: [Matplotlib-users] Vertical bar - making the bar fixed width
So, if I understand correctly, this is a cosmetic issue: If you let it sort out its own scale, it looks a bit ugly when there are a small number of data points? And using a fixed re-scale of 0-10 isn't too great either 'cause they're all together at one side of the image... (or off the edge of it if there are more than 10 points) With the normal caveat that my suggestion is unlikely to the best way of doing it, how about: If there are less than some number of datapoints, say 5, move the datapoints to higher x and rescale the axis, if there are more than 5, let matplotlib handle everything automatically: ind = arange(N, dtype=float) # the x locations for the groups if N < 5.0: ind += (5.0-N)/2.0 # Slide the x points up # draw the bars here if N < 5: xlim(0, 5) # Rescale If you do this I think (but I haven't checked) you'll also need to change: for i in xrange(N): text(i, 0, " %s" etc...) to: for i in ind: text(i, 0, etc...) in order to keep the text lined up right.

Thanks, I'll look at this asap (as I got other stuff "on fire").
BTW, I can't ever get (in fact, I don't know how) working
the coords to be displayed in my traits app.
I guess this is more related to traits, not to mpl.
But the "mpl embedded in traits app guru" is on holydays for now.
Let's wait...

In fact, I would like something like datad for colormaps.
I use it like this:
def __init__(self, **traits):
HasTraits.__init__(self, **traits)
dict_colormaps = copy(datad)
self.cmap = get_cmap(self.default_colormap)
for cm in dict_colormaps.keys():
if (cm[-2:] == '_r'):
dict_colormaps.pop(cm)
Doing this, I can display in my traits app the list of colormaps.
I would like to have something similar for available interpolation
methods.
I guess that implies to remove intperd from the AxesImage class,
as datad does not belong to any class, IIUC.
Obviously, I can build this list myself, hard-coding it,
but I would prefer something "cleaner".

Well..., I forgot to mention something, sorry ;-)
I already apply this trick: I use get_{x,y}lim and set_{x,y}lim.
Which works almost fine.
In fact, I use a grid, which is defined by xmin, xmax, dx & ymin, ymax, dy.
I don't want do display on the axes the number of points, but the real world
axis dimension.
If xmin=ymin=0 and xmax=ymax=500 with dx=dy=1,
the trick does work fine.
Now, if I set xmax=ymax=1000 but dx=dy=2 (so I have the same number of
points)
I have to use imshow extent option, because of the use of _xlim & _ylim.
Please see http://fredantispam.free.fr/a.png without extent option,
http://fredantispam.free.fr/b.png with extent option.
But in this case, after zoomed,
see http://fredantispam.free.fr/c.png
the trick does not work anymore: x & y limits are right,
but the whole data is displayed by imshow.
see http://fredantispam.free.fr/d.png.
Maybe I'm doing something wrong ?
TIA.

Re: [Matplotlib-users] displaying only one colorbar... [fixed]
Eric Firing a écrit : > You may need to post a small code example so we can see what you are > doing; but an interactive example using ipython -pylab may give you > enough information to answer your question: Hi , Not really ;-), but no problem. I got a fix. The trick is to pass axes colorbar as argument to colorbar function: def update_colorbar(self): if (self.cb is None): self.cb = self.display.figure.colorbar(self.img, ticks=self.cbticks, format='%g') else: self.display.figure.colorbar(self.img, self.cb.ax, ticks=self.cbticks, format='%g') that works perfectly.

[Matplotlib-users] displaying only one colorbar...
Hi, My issue is quite simple: I reload several times an image with the colorbar enabled, and thus, I have several colorbars, not only one. How can I disable this, and thus, get only one colorbar ?

[Matplotlib-users] fonts_demo.py warnings
Hi the list,
I have looked for in mailing-list archive, but did not find anything
relevant.
I use matplotlib 0.87-5 and I want to try some examples concerning fonts
in .examples/.
When I run fonts_demo.py, I get the following messages :
:~...matplotlib-0.87.5/examples/{58}/> python fonts_demo.py
/usr/local/lib/python2.4/site-packages/matplotlib/font_manager.py:989:
UserWarning: Could not match cursive, normal, normal. Returning
/usr/local/lib/python2.4/site-packages/matplotlib/mpl-data/Vera.ttf
warnings.warn('Could not match %s, %s, %s. Returning %s' % (name,
style, variant, self.defaultFont))
/usr/local/lib/python2.4/site-packages/matplotlib/font_manager.py:989:

/usr/local/lib/python2.4/site-packages/matplotlib/mpl-data/Vera.ttf
warnings.warn('Could not match %s, %s, %s. Returning %s' % (name,
style, variant, self.defaultFont))
What am I doing wrong ?
In fact, all fonts displayed in the window are the same.
Any suggestion ?
Cheers,
PS : python 2.4, freetype-2.1.7-6, libpng-1.2.8 on a debian sarge linux box.
