I'm having difficulty producing dynamic plots on OS X using matplotlib
0.73.1 and wxPython 184.108.40.206 on OS X 10.3 with Python 2.3.5
The code below works with the same configuration on Fedora Core 3,
producing a graph with a line that pivots at the origin. On OS X,
however, the frame remains blank and grey until the final plot is drawn,
when the plot takes on the correct final state.
I've tried similar examples with bar graphs and scatter plots, and the
same results are produced. I don't know if this is a problem with
matplotlib or wxPython, and any help would be gratefully appreciated.
If you need any more info to help, let me know.
The example code is:
from matplotlib.backends.backend_wx import FigureCanvasWx
from matplotlib.figure import Figure
from matplotlib.axes import Subplot
from Numeric import pi, sin, arange
wx.Frame.__init__(self, None, -1, "Test embedded wxFigure")
self.fig = Figure((5,4), 75)
self.canvas = FigureCanvasWx(self, -1, self.fig)
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(self.canvas, 1, wx.LEFT|wx.TOP|wx.GROW)
self.a = self.fig.add_subplot(111)
x = arange(0,2*pi,0.01) # x-array
self.line, = self.a.plot(x,x)
def update_data(self, i):
if __name__ == '__main__':
app = wx.PySimpleApp(0)
frame = PlotFigure()
for i in arange(1,200):
