[Matplotlib-users] PySide and blit-style animation problem
Hello,
I have adopted blit animation example [1] to use it inside PySide Qt
widget. But I found a little problem. When I follow the example [1] and use
self.blit(self.axes.bbox) call in 'draw_event' callback, the ugly black
frame is
appeared during the application window zoom (changing size of the window).
But when I remove this line everything works well. But I does not
understand why?
Please, see the code below:
import sys
from PySide import QtCore, QtGui
from matplotlib import rcParams;
rcParams['backend.qt4'] = 'PySide'
from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as Canvas
from matplotlib.figure import Figure
from matplotlib.lines import Line2D
class MatplotlibWidget(Canvas):
def __init__(self, parent = None):
# figure
self.figure = Figure()
self.axes = self.figure.add_subplot(111)
self.axes.plot([0.0, 1.0])
# markers
self.marker_id = None
self.x = [0.3, 0.7]
self.y = [0.5, 0.5]
self.markers = Line2D(self.x, self.y, ls = ' ', marker = 'o',
picker = 5, animated = True)
self.axes.add_line(self.markers)
# initialization with current figure
super(MatplotlibWidget, self).__init__(self.figure)
self.setParent(parent)
self.setSizePolicy(QtGui.QSizePolicy.Expanding, QtGui.QSizePolicy.Expanding)
self.updateGeometry()
# events
self.mpl_connect('draw_event', self.on_draw)
self.mpl_connect('pick_event', self.on_picked)
self.mpl_connect('button_release_event', self.on_button_released)
self.mpl_connect('motion_notify_event', self.on_motion)
def on_draw(self, event):
self.background = self.copy_from_bbox(self.axes.bbox)
self.axes.draw_artist(self.markers)
# this line of code cause ugly black frame over the plot during the
# window zoom (changing app window size)
self.blit(self.axes.bbox)
def on_picked(self, event):
self.marker_id = event.ind
def on_button_released(self, event):
if event.button != 1:
return
self.marker_id = None
def on_motion(self, event):
if event.inaxes is None:
return
if event.button != 1:
return
if self.marker_id is None:
return
x, y = event.xdata, event.ydata
self.x[self.marker_id] = x
self.y[self.marker_id] = y
self.markers.set_data([self.x, self.y])
self.restore_region(self.background)
self.axes.draw_artist(self.markers)
self.blit(self.axes.bbox)
class ApplicationWindow(QtGui.QMainWindow):
def __init__(self):
super(ApplicationWindow, self).__init__()
self.setWindowTitle("Animation Demo")
self.setCentralWidget(MatplotlibWidget())
def main():
app = QtGui.QApplication(sys.argv)
appWindow = ApplicationWindow()
appWindow.show()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
My environment:
Ubuntu 12.04, python-matplotlib 1.1.1~rc1+git20120423-0ubuntu1

Re: [Matplotlib-users] Kubuntu 13.04 : can't import matplotlib.pyplot
Sorry for disturb. It was due to an old manual install of numpy.

[Matplotlib-users] Add support for Smith charts
Hello, I created a project for plotting nice Smith Charts with matplotlib. I followed the projection example. I put my code into a git repo on github: https://github.com/vMeijin/pySmithPlot Iwanted to ask, if there is any interest in putting this functionality into the main library. If so, I would try to adapt my code and make a pull request, but it would be wasted time, if no one is considering to accept it. -- AlienVault Unified Security Management (USM) platform delivers complete security visibility with the essential security capabilities.

Personally, I have never heard of smith plots, and wouldn't know what the use case would be, but I think we could definitely include most, if not all of it into mpl. At the very least, the projection itself is quite interesting and might be cool to add.

It's been a few years since I had heard that name, but now I remember a bit the few undergrad courses I got on HF electronics and transmission lines. For the inclusion, I feel it should, at the very least, be in the gallery. best, Pierre -- AlienVault Unified Security Management (USM) platform delivers complete security visibility with the essential security capabilities.
