[Matplotlib-users] Problem with redrawing of plots

[Ghupi <fg...@fr...>]

Hello,
with the following source code, in which show_function is called after a key
event, I have 2 problems :-/:

1) each new drawing (i.e. new call of show_function) leads to a indermediate
redrawing of the previous plots, making the program slow

2) the 'button_press_event', which prints xdata/ydata, always prints the
coordinates of the first plot (so as if the axes are not updated by calling
show_function).

Any ideas? :working:

Thanks in advance!

Frederik



class CanvasFrame(wx.Frame):
	def __init__(self, ):
		wx.Frame.__init__(self,None,-1,'',size=(644,555))
		
...

def show_function(self,xname,x,yname,y,bestbkgr,bestprm,filename,numscan):	
		from pylab import
plot,legend,title,xlabel,ylabel,show,close,figtext,savefig,clf
		
		self.frame=wx.Frame(self,-1)
                self.figure = figure()
                
                self.axes = self.figure.add_subplot(111)
		
		self.axes.plot(x,y,'k.')
		self.figure_canvas = FigureCanvas(self, -1, self.figure)
                
		self.sizer = wx.BoxSizer(wx.VERTICAL)
		self.sizer.Add(self.figure_canvas, 1, wx.EXPAND|wx.CENTER|wx.GROW)
		self.SetSizer(self.sizer)
		self.Fit()

		self.figure_canvas.mpl_connect('button_press_event', self.click)
