Re: [Matplotlib-users] images from data

[Eric F. <ef...@ha...>]

Michael,

How easy it is to do this depends on your ascii file format, and how the 
data are organized in it.  Are the points in order? e.g.

x0, y0, z00
x0, y1, z01
x0, y2, z02
x1, y0, z10
x1, y1, z11
x1, y2, z12

Are the values space-delimited, or comma-delimited, or in some other format?

Is the grid uniform in the sense that all the x-intervals are the same 
and all the y-intervals are the same?
