[Matplotlib-users] how to get the properties for elements in a collection?
Hi, I have a collection, which is a scatter plot, and I want to iterate through all the elements in this collection and retrieve their properties, like facecolor. the scatterplot is created like this: axes.scatter(x,y, c=some_list, cmap=plt.get_cmap(colmap)) many thanks -- Carlos Henrique Grohmann - Geologist D.Sc. a.k.a.

I'd like my app to show a progress bar while some gridding and
contouring are being done.
this is the code I'm using (without preogress bar)

"Triangulation":'linear',"Multiquadric":'multiquadric',"Inverse
Multiquadric":'inverse multiquadric',"Gaussian":'gaussian',"Linear

# check what kind of interpolation are we using

zi = griddata(node_x,node_y,z,xi,yi,interp=funcs[interp])
else: # Radial basis functions (scipy)
ti = np.linspace(-1.1,1.1,ngrid)
xi, yi = np.meshgrid(ti, ti)
rbf = Rbf(node_x, node_y, z,
function=funcs[interp],epsilon=epsilon,smooth=smoothing)
zi = rbf(xi, yi)
## we only want the points that lie inside the circle,
## so we have to create a polygon to select the interpolated values
polyXY = []
u = np.arange(0,361,1)
t = np.radians(u)
x = np.cos(t)
y = np.sin(t)
polyXY.append(zip(x,y))

[Matplotlib-users] exclude something from legend
Hello all,
Is there a way to tell MPL that something I plotted (like a series of
Line2D, to create a grid) should not be considered for the legend?
I'm plotting a lot of things, and because of these objects (without
label), I always got these msgs:
/usr/lib/pymodules/python2.6/matplotlib/axes.py:4014: UserWarning: No
labeled objects found. Use label='...' kwarg on individual plots.
warnings.warn("No labeled objects found. "

[Matplotlib-users] problem with MPL+py2exe (wx app needs qt?)
Hello all, I'm trying to build an executable distribution of an app I'm working using py2exe.

The .log file shows me that the module backend_qt4agg wasn't found: > ImportError: No module named backend_qt4agg Also, using py2exe -x shows me that PyQt4 is being imported by matplotlib.pyplot.

Re: [Matplotlib-users] problem with MPL+py2exe (wx app needs qt?)
Many thanks, that helper.
After some more problems with scipy, I got a working EXE.
PyQt4 is still in the library, though. Eating almost 15Mb... Now all I
have to do is to find out how to remove it..
cheers

[Matplotlib-users] py2exe and matplotlib - Fonts: do I need them all?
Hello all, I'm new to py2exe but I managed to create a binary executable of my program. Now I'm experiencing on how to make the final size of the binary smaller. I already managed to cut about 15Mb by removing calls to pyQt (I use Wxpython) and also to scipy. One thing that is still bothering me is the mpl_data directory that holds about 3.5 Mb of fonts. Is it OK to remove the fonts I don't use? (I use only sans-serif) By Ok I mean not only from the practical poin tof view (that is, will the app run?) but also from the _legal_ point of view (am I obliged to distribute all those fonts?) And what about all thos .afm files? Are they needed? What are they really? I hope to find some answers from your experience. best Carlos -- Prof. Carlos Henrique Grohmann - Geologist D.Sc.

[Matplotlib-users] automatically change file extension when saving
Hi there,
I've been looking for a way to automatically set the extension of a
file when saving a plot via the navigationBar 'save' button. In my
case, when I change the file type, the extension of the default
filename ('image.png') won't change. I'd like it to change to the
extension of the file type I selected.
best

[Matplotlib-users] issues when saving files - no automatic extension added in dialog
Hello all, I'm developing a software for Geology, using wxpython for the GUI. When I want to export any graphics, clicking on the "save" button on the MPL toolbar, I get a dialog to save the file (with a default "image.png" filename) and where I can choose between some file formats. When I select any format from the drop-down list, I expected it to change the extension of the file on the dialog, but it doesn't. So I have to set it up manually. Is this a bug? thanks -- Prof. Carlos Henrique Grohmann - Geologist D.Sc.

[Matplotlib-users] fixing figure size on wxpython app
Hi all,
I'm developing an app for structural geology called OenStereo (
www.igc.usp.br/openstereo), using matplotlib and wxpython.
So far, I'm really happy with the results, but there is still one thing
annoying me: when I save the plots (using the save icon in the
NavigationToolbar),
the resulting figure size is determined by the size of the window. Can I set
this to a fixed value (like 15cm)?
this is a part of the code where I create the figure:
#initialize the figure and canvas
self.stereoFigure = Figure(figsize=(4,4),facecolor='white')
self.stereoCanvas = FigureCanvas(self, -1, self.stereoFigure)
self.toolbar = VMToolbar(self.stereoCanvas)
self.stereoCanvas.mpl_connect("motion_notify_event", self.OnMove)
#initialize the plot area
self.plotaxes = self.stereoFigure.add_axes([0.01, 0.01, 0.6, 0.98],
clip_on='True',xlim=(-1.1,1.2), ylim=(-1.15,1.15),
adjustable='box',autoscale_on='False',label='stereo')
self.plotaxes.set_axis_off()
self.plotaxes.set_aspect(aspect='equal', adjustable=None,
anchor='W')
best
