Dear list members,
Hello.
I am a new member of this list. This is my first email, hope I will be
able to send it correctly.
I have three requests concerning the code below:
1) I would like to have 4 different colors in the red curve,
one for which natural part of the curve.
2) the curve should stop around the point (13,-16).
3) the two label <-1> of the axes are not well placed. How NOT to put
them in the axes?
Thank you for your help.
Luis
