[Matplotlib-users] to much points

Hi All, my program lets slow down my cpu. This only appears if i plot to much points. I am not sure how many point i need to get this, normally i plot 3*14e6 + 8e3, that is round about 50million points. My system is a dual core 2GHz cpu with 2Gbyte Ram. Here is my method to plot, def drawtra

[Matplotlib-users] setp for bar() Elements

Hi All, i am in need of set the properties of my bar() Element, by using a slider. For plots this looks like this: self.plot = self.subplot1.plot(x,y) setp(self.plot, xdata=new_x, ydata=new_y) How to do this with this, self.bar = self.subplot2.bar(x,y) ??? Any Hints ? Regards Markus ---

[Matplotlib-users] setting x-Axis of bar() element in wxwidget application

Hi All, i am programming an application which extracts binary values from 6 files and plots this values in a bar() element and another one. The bar Elements are partial one upon the other. I think this results of my my small x values. y1 = [1 0] y2 = [1 0] y3 = [1 1] x = [ 0. 0.0002149]
