I have question and want to see if it can be realized in wxpython.
   I would like to plot data on wxpython, and then use the mouse to select some points which are plotted, using the mouse.
At the moment i am using wx.lib.plot and using the PlotMarker
Is there a way of doing this with wx.lib.plot or do i have to use another graph library 
Regards!
You can use matplotlib or pygal. Something similar with your describing technique is used in PyQtGraph.
