I wrought something like
client = plot.PlotCanvas(childFrame2, 2,pos=(300,400),size=(100,200),
name=text1)
But the plotcanvas kept filling all the childFrame.
Is there a way to Really adjust the size of ploscanvas?
Thanks in advance for your help.

The problematic code is below:

class FrameWithAButton(wx.Frame):
def __init__(self, parent, id, title, list=[]):
wx.Frame.__init__(self, parent, id ,title, size=(500,200))
self.data = xyList
self.xList = []
self.yList = []
for (x,y) in self.data:
self.xList.append(x)
self.yList.append(y)
panel = wx.Panel(self, -1)
wx.Button(panel, 1, 'scatter', (10,10))
wx.Button(panel, 2, 'regression line with scatter', (10,40))
self.Bind(wx.EVT_BUTTON, self.on_scatter, id=1)
self.Bind(wx.EVT_BUTTON, self.on_line, id=2)

def on_scatter(self, event):
"""Plot the points in xyList.

"""
childFrame1 = wx.Frame(self, -1, 'scatter', size=(800,600))
client = plot.PlotCanvas(childFrame1)
markers = plot.PolyMarker(self.data, legend='Zipf\'s law',
colour='red', size=1)
gc = plot.PlotGraphics([markers], 'Scatter', 'logr', 'logf')
client.Draw(gc, xAxis=(0,9), yAxis = (0,10))
childFrame1.Show(True)

def on_line(self, event):
"""Plot the points and draw the regression line out of xList and
yList, inside a Plot Canvas panel;

"""
#Succeded in making the graph, but failed to set the position of
PlotCanvas.
#The pos=(300,400) just did not work! kaipo 2010/04/28 19:20
(meanX, meanY, betaZero, betaOne, sumYY) = cal_beta(self.xList,
self.yList)
childFrame2 = wx.Frame(self, -1, 'regression line with scatter',
size=(800,600))
text1="logf = %.03f" %betaZero +" %.03f logr" %betaOne
client = plot.PlotCanvas(childFrame2, 2,
pos=(300,400),size=(100,200), name=text1)
regLine = plot.PolyLine([(0.0, betaZero),
((0.0-(betaZero/betaOne)), 0.0)],width=1, colour='blue')
markers = plot.PolyMarker(self.data, legend='Zipf\'s law',
colour='red', size=1)
gc = plot.PlotGraphics([markers, regLine], text1, 'logr', 'logf')
client.Draw(gc, xAxis=(0,15), yAxis = (0,12))
childFrame2.Show(True)

In wxPython, if you add a widget directly to a frame it will
automatically expand to fill the frame. Instead, add a wxPanel to the
frame and add your plot canvas to that panel.

wxPython questions are best asked on the wxPython list, which is also
on Google Groups or you can email subscribe to it.

Thanks a lot.
I'll check the wx list.
