Hi everyone,

i am having trouble making circular globes in IDL. Here is some sample
code for X:

window, xsize=500, ysize=500 ; should be square, pixels are...
map_set, 0, 0, /ortho, /horiz, /grid ; produces a rectangle and oval

;;;in ps:
set_plot, 'ps'
device, xsize=10, ysize=10 ; should be a 10x10 cm square image
map_set, 0, 0, /ortho, /horiz, /grid ; produces a 10x10.5 grid

any suggestions or ideas as to why the above code produces rectangles with
ovals inside rather than squares containing circles?

thanks,
ken.
