Nice program, even though it is still rough and has a few problems, as you
mentioned. I looked over your code and if I understand the problem about
the flipped Y-axis problem, I believe it can be fixed fairly easily.
First, in procedure initial() change the end of line defining the Y axis in
the sequence Center from: *300+50}
To: *-300+350}
In procedure draw_it() delete the statement: Y = -Y
Also in the same procedure, in the statement draw_line (YELLOW,.......
add the minus sign to the Y axis statements as shown:
, -prevY*Scale[2]+Center[2]},
and , -Y*Scale[2]+Center[2]}})
Hopefully this helps,
Happy New Year
