Re: [Matplotlib-users] jitter in matplotlib?
I haven't seen this done before so I don't know if there's a standard way. The idea seems to be to take some points which are real data, create a random variable for each point with the points' position as the mean, then choose some number of points from each distribution to create some new points clustered around the original data. Some examples online seem to use uniform distributions and Poisson distributions or mixtures of these (uniform for the x-variable and Poisson for the y). If my take on this is correct, you can use scipy.stats to do this - an example is in the attached file which creates Gaussian distributions for each of the x and y coordinates then creates an equal number of new points for each of the seed points. The online examples I saw seem to choose random numbers of new points for each seed point. I didn't bother trying to cover all the possibilities. Hopefully this is helpful, Gary R.

Re: [Matplotlib-users] Matplotlib Widget and QT Issue
Jason, Try adding a pyqt property 'facecolor' to your widget. (This way you can set it also through the designer.) Add something like this to the widget's __init__ method: figFacecolor = QtCore.pyqtProperty(str, getfigfacecolor, setfigfacecolor, resetfigfacecolor) And then define the three methods.

Re: [Matplotlib-users] figure window coordinates

Currently when I make new plots they appear in random locations as determined by my operating system; during analysis when I'm making and destroying a lot of plot windows I want to be able to have them automatically appear in good locations (such as the upper left corner of my screen). Also, I am trying to find ways to get/set the z-order. Thanks in advance, Jack There was someone who found that it was possible to add some additional information to the creation of a figure window. This information (at least on Linux systems), could be taken advantage of by customized configurations of the desktop manager. I would be curious to see what has come of that effort.

Re: [Matplotlib-users] Histogram with single series - colour coding different ranges?
2011/2/22 Benjamin Root ben.r...@ou.edu: Admittedly, this isn't using matplotlib's hist() function because it only allows for one color per dataset. However, you can use numpy's histogram function to get the bins and counts yourself, and then use bar() to make the bars. bar() will allow you to color the bars individually. Pylab hist() returns a list of patches so you can also change their properties. Goyo -- Free Software Download: Index, Search Analyze Logs and other IT data in Real-Time with Splunk.

Re: [Matplotlib-users] faq: reducing figure.figsize cuts off labels and tick marks
On Tue, Feb 22, 2011 at 4:23 AM, Daniel Mader danielstefanma...@googlemail.com wrote: Hi, there has been a similar question recently but I couldn't figure out if or how this is solved: I'd like to reduce the figure size so that I can add it to a LaTeX document without scaling (PDF output with LaTeX font rendering). For that, I need to adapt the font sizes, too. Unfortunately, the canvas is not properly scaled so that the axis labels and the possibly the tick marks are cut off. Is this a bug, feature, design flaw? How can I properly work around it, i.e. reduce the graph automatically for a given figsize/font size combination so that everything fits on the figure? An example follows to demonstrate, thanks in advance I use matplotlib for this purpose pretty frequently. A few tricks: from http://matplotlib.sourceforge.net/users/customizing.html : # note that font.size controls default text sizes. To configure # special text sizes tick labels, axes, labels, title, etc, see the rc # settings for axes and ticks. Special text sizes can be defined # relative to font.size, using the following values: xx-small, x-small, # small, medium, large, x-large, xx-large, larger, or smaller # specify the figure canvas size, in inches figure(figsize=(3.4, 4)) # place the axes in the figure window # specifying (left, bottom, width, height) as fraction of figure size # adjust those positions to make enough room for tick and axis labels axes([0.15, 0.12, 0.8, 0.83]) Specify the dpi for you screen, so the figure rendered on your screen is the correct size. This is figure.dpi, best to set it in matplotlibrc. Darren -- Free Software Download: Index, Search Analyze Logs and other IT data in Real-Time with Splunk.

Re: [Matplotlib-users] Qt integration and sip API
Following up, after a bit of research...
It seems it's alla about QString (which is gone in api 2)
it is suggested to convert the QString into a unicode python2 string
http://wiki.python.org/moin/PortingPythonToPy3k/PyQt4
Do you think could be the way to go for the qt backend?
Cheers,
Michele.

I'm wondering if I'm the first to stumble upon this one, or this is a

Below the whole Traceback.
