Re: [ferret_users] aspect ratio

[Ryo Furue <furue@xxxxxxxxxx>]

Daiwei,

| how can i get the aspect ratio (geometric or geographic) of each
| plotting region (not viewpoint itself) in a multi-viewpoint window?
| my purpose is to adjust the direction of velocity vectors
| propotional to the scaling of plotting area. any thoughts?

I guess what you want is

    vector/aspect/. . .  u,v

Also, $ppl$xlen and $ppl$ylen have the lengths of the current
plotting window in inches.

Hope this helps.

Ryo
