Wow! That was so easy. Thanks. I guess I never really think of the
array indices as 'positions',
Thanks for the help,

After you import the data, you can pass it through a MARK->COMPUTE-

control, where you can change the coordinates from polar to cartesian:

b
[a.x*cos(a.y),a.x*sin(a.y)]
Don't forget to mark the positions before you make the transform.

Hi-
I have some 2d data where the data is stored in a 1024 square array,
but the positions are not regular. That is, the data was made in a
simulation in polar coordinates (r, theta). I can't figure out how to
tell DX that this is the case. How do I construct a grid with polar
coords and then get DX to display the data in the proper format (i.e.
the grid ought to look like a pie slice, rather than square).
Any ideas would be helpful.
Thanks,
Dan
