[gradsusr] How to use draw function

[Heiner Körnich]

Hi,

it is actually a little confusing. The draw command uses the coordinates of
your drawing window. Those coordinates range from 0 to 8.5 and 0 to 11 inch.
The coordinates that you were using are the world coordinates. Use the
function "q w2xy" to convert from world to xy coordinates, eg. for 65 deg
east and 10 deg north
q w2xy 65 10

Regards,
Heiner
