Nice to hear that transition will be easy. Unfortunately I'm already using
Numeric 24.0. I wrote a small example using wxPython which works with Numeric
but doesn't with scipy.base:
import wx
from wx.lib import plot
from scipy.base import *
#from Numeric import *
class MyApp(wx.App):
def OnInit(self):
wx.InitAllImageHandlers()
frame = plot.TestFrame(None, -1, "PlotCanvas")
#frame.Show(True)
gr = plot.PlotGraphics([plot.PolyLine(transpose([arange(10),arange(10)]))])
frame.client.Draw(gr)
self.SetTopWindow(frame)
return True
app = MyApp(0)
app.MainLoop()
