Someone more knowlegeable than me may corrct me here, but the code for
getting your data into a grid could be greatly simplified to:
X = array([0,1,2,3,4,5,6,7,8,9,])
Y = array([0,1,2,3,4,5,6,7,8,9,])
Z = ListValues.reshape(10,10)
than you could use something like imshow() to show the data without any
interpolation.
