Thanks for the responses so far, everyone. Luis you are indeed a good guesser! I'm using wxPython/matplotlib and would like to size my matplotlib data figure so that it assumes a 1:1 ratio on the screen when embedded in a wxPython form. I'm playing with a 2D array with 320 rows and 177 columns and therefore would like to display the figure with a size of 320x177 pixels. The problem is that the call to instantiate the figure takes size parameters of inches and dpi! For example: matplotlib.figure.Figure((5,4), 75) is a figure with width of 5 inches, height of 4 inches, and dpi of 75. Thanks to Luis' comment I googled around and found that wxPython has the following functions: wx.GetDisplaySize() # Get dimensions in pixels. wx.GetDisplaySizeMM() # Get dimensions in millimeters. It's a little klunky to have a function that takes inches an an argument and another that produces millimeters when querying the display, no? Unless someone has a better idea I suppose I'll have to convert between the two to display at 1:1. -L SInce I want my matplotlib.figure.Figure() to assume the exact pixel dimensions of the 2D array, -- http://mail.python.org/mailman/listinfo/python-list
