[ferret_users] How to plot polygons?

[hengkek@xxxxxxxxxx]

Hi all

I have an ascii file with 8 columns and multiple rows in the following 
format:

x1 y1 x2 y2 x3 y3 x4 y4
...

where (x1,y1) thru (x4,y4) are vertices of polygons I'd like to plot.

I'm not sure how to form the arrays to use POLYGON.  I.e. what to do 
after "FILE/VAR=X1,Y1,X2,Y2,X3,Y3,X4,Y4 MYFILE.TXT"?

Thanks for any tips.

Sincerely
Kek
