aline
Dear Ferret Users
I have 4 arrays: x1,y1,x2 and y2 and want draw several lines: i.e.
from x1(1),y1(1) to x2(1),y2(1) and so on
I've tried using aline:
repeat/i=1:50 (ppl aline 1,x1[i=`i`],y1[i=`i`],x2[i=`i`],y2[i=`i`])
But this runs through the routine without plotting anything - yet when I
type in the actual values of x1,y1,x2,y2 as a test, the appropriate line
gets plotted on screen.
Any thoughts on what might be going wrong - am I using incorrect syntax?
Typing list x1[i=1] etc returns the appropriate values.
Thanks for your time
Richard
