THE ACTUAL THING I WOULD LIKE TO DO ARE AS FOLLOWS
I GOT A GRAPHIC -COLLUMS ARE 80000 TO 180000 AND LINES ANRE 460 TO 560.
WHAT I WOULD LIKE TO DO ARE AS FOLLOW.
LETS SAY X = 500 AND Y ARE 160000 IT SHOULD GIVE ME 90º AS 500 ARE 90º.
IF I CHANGE IT TO X 490 AND Y 160000 IT SHOULD GIVE ME ANOTHER ANGLE.
Please explain why when x=500 and y=16000, the angle is 90°
By the way - please turn off the CAPS key - a message in all block letters
is called shouting and considered poor manners (and is hard to read).
best wishes
