[Matplotlib-users] Ubuntu server package PPA python-matplotlib-nox ?
Does anyone maintain a PPA with a python-matplotlib-nox suitable for Ubuntu
11.04 amd64 server i.e. built without X or GUI libraries?
On a fresh Ubuntu server install, python-numpy has relatively few dependencies,
but python-matplotlib pulls in everything the full GUI needs.
$ sudo aptitude install python-matplotlib -s

[Matplotlib-users] Bus error when using logarithmic scale with logaritmic bins
Dear colleagues,
I'm trying to display an histogram with logarithmic bins using the
logarithmic scale in the x-axis. When I execute the attached python
script it crashes giving a "Bus Error" message (see also the attached
core dump).
If I remove the line "plt.xscale('log')" the script goes up to the end.
I'm running the program on MacOS 10.6.8, Python 2.5, numpy 1.2.1, and
matplotlib 0.98.5.2.
Anyone knows the reason of the crash?
Thanks,
marc

[Matplotlib-users] Polygon radar plot instead of circular?
Hi everyone, I'm trying to construct a radar plot for 5 variables. I've found the example code (radar_chart.py) for doing this with matplotlib but I'm having trouble adjusting one aspect of the rendering. That sample file produces radar plots with circular frames and ticks (see http://wineinger.me/plotting/radar_chart1.png). That sample code does seem to have an option to use a polygon frame rather than a circle (the default), but this doesn't seem to do much except erase part of the outer tick lines ( http://wineinger.me/plotting/polygon.png vs http://wineinger.me/plotting/circle.png). Plus, I'm looking for the tick lines to parallel the frame, so having a polygon frame with circular ticks would not be useful to me. Here is an example of what I'd like to produce: http://www.corda.com/docsource/doc7/Manuals/project_graphics/design_graphs_radar_transparency.gif. Can anyone provide some sample code to get me started or at least some direction on how to accomplish this? I'm new to matplotlib though I do have a fair bit of python experience. thanks!

If I remember correctly, there was a log-scale bug in plt.hist() that got
fixed a little while back. Your version of numpy and matplotlib is a little
old. Is it possible to update those two packages on your system?

Hi Ben,
I will try to do it. Once it is done I let you know.
Cheers,

Improvements to matplotlib have, however, broken this example. If you plot this on a non-white background, you'll see that there is indeed a polygon patch for the axes. Nevertheless the border (i.e. "spine") of the plot is circular because of improvements that separated the spine from the patch. The example code only overrides PolarAxes._gen_axes_patch, but should also override PolarAxes._gen_axes_spines to fix this issue. Unfortunately, I don't have time to work on this. > Plus, I'm looking for the tick lines to parallel the frame, so having a > polygon frame with circular ticks would not be useful to me. > I thought the grid was correctly rendered as polygons instead of circles (when choosing a polygon frame). I don't, however, see anything in the example code to change the grid lines, so my memory might be wrong.

[Matplotlib-users] NavigationToolbar2QT change height
First of all congratulation for the release 1.1.0 of matplotlib it's a
wonderfull.
since the version 0.90 I started to use it, I keep enjoy it everyday. I
work with PyQT4 and PySide.
I try to modify the height of the NavigationToolbar2QT, but no matter I
use "resize" the Qt4 method nothing happen.
code available: http://pastebin.com/8KW2dWG2
#...# all Qt imports
from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as
FigureCanvas
from matplotlib.backends.backend_qt4 import NavigationToolbar2QT as
NavigationToolbar
class MPL_widget(QWidget):
def __init__(self,parent):
QWidget.__init__(self,parent)
self.canvas = FigureCanvas()
self.toolbar = NavigationToolbar(self.canvas,self.canvas)
self.toolbar.resize(100,10) #
self.vbox = QVBoxLayout()
vbox = self.vbox
vbox.addWidget(self.canvas)
vbox.addWidget(self.toolbar)
self.setLayout(vbox)
I tryed to modify directly in matplotlib module
'matplotlib.backends.backed_qt4' in the constructor of
NavigationToolbar2QT just after the call of QToolBar.__init__(), nothing
happen either.
finaly I added a QSplitter, which let me hide the bar during runtime,
but my first goal was rather to reduce the size and all icon inside.
from PyQt4.QtCore import *
from PyQt4.QtGui import *
import PyQt4.QtGui as QtGui
import matplotlib
if matplotlib.get_backend() != "Qt4Agg":
matplotlib.use("Qt4Agg")
from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as
FigureCanvas
from matplotlib.backends.backend_qt4 import NavigationToolbar2QT as
NavigationToolbar
from matplotlib.figure import Figure
class MPL_Widget(QWidget):
def __init__(self, parent = None):
QWidget.__init__(self, parent)
self.fig = Figure(figsize = (10, 12), dpi=100, facecolor =
'#FF')
self.ax = self.fig.add_subplot(111, sharex = None, sharey = None)
self.canvas = FigureCanvas(self.fig)
self.toolbar = NavigationToolbar(self.canvas, self.canvas)
self.toolbar.resize(10,10)
# this line does nothing
self.vbox = QVBoxLayout()
tmp = self.vbox
tmp = QSplitter()
tmp.setOrientation(Qt.Vertical)
tmp.setContentsMargins(0,0,0,0)
tmp.addWidget(self.canvas)
tmp.addWidget(self.toolbar)
self.vbox.addWidget(tmp)
self.setLayout(self.vbox)
self.layout().setContentsMargins(0,0,0,0)
import sys
app = QApplication(sys.argv)
w = MPL_Widget()
import numpy as N
x = N.linspace(-10, 10)
y = N.sin(x)
ax = w.ax
ax.plot(x, y, 'o-', mew=0)
w.show()
sys.exit(app.exec_())
Any hint would be appreciate.
Cheers.
