Hello,
When I try to use transData.transform on a log plot, an error occurs :
...
File "E:\Python26\lib\site-packages\matplotlib\transforms.py", line
1895, in transform
self._a.transform(points))
File "E:\Python26\lib\site-packages\matplotlib\transforms.py", line
1723, in transform
x_points = x.transform(points[:, 0])
TypeError: tuple indices must be integers, not tuple
Here is an example :
#!/usr/bin/env python
import matplotlib
matplotlib.use('WXAgg')
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as
FigureCanvas
from matplotlib.figure import Figure
import wx
class CanvasFrame(wx.Frame):
def __init__(self):
wx.Frame.__init__(self,None,-1,
'CanvasFrame',size=(550,350))
self.SetBackgroundColour(wx.NamedColor("WHITE"))
self.figure = Figure()
self.axes = self.figure.add_subplot(111)
self.axes.set_xscale('log')
p1 = (1,1)
p2 = (2,2)
_x1, _y1 = self.axes.transData.transform(p1)
_x2, _y2 = self.axes.transData.transform(p2)
_xy = [[_x1, _y1], [_x2, _y2]]
xy = self.axes.transData.inverted().transform(_xy)
self.axes.plot(xy)
self.canvas = FigureCanvas(self, -1, self.figure)
self.sizer = wx.BoxSizer(wx.VERTICAL)
self.sizer.Add(self.canvas, 1, wx.LEFT | wx.TOP | wx.GROW)
self.SetSizer(self.sizer)
self.Fit()
class App(wx.App):
def OnInit(self):
frame = CanvasFrame()
frame.Show(True)
return True
app = App(0)
app.MainLoop()
If I comment the line : self.axes.set_xscale('log'), it works fine.
python 2.6.4
wxpython 2.8.10
mpl 0.99
Thanks by advance for your help.
