Subject: Re: [lazarus] TAChart and Parabola graph
We develop mathematical products, and our math experts told me it is a
"parabola" that they need. I added the "graph" bit. :-)
http://dictionary.reference.com/search?q=parabola
[A plane curve formed by the intersection of a right circular cone and
a plane parallel to an element of the cone or by the locus of points
equidistant from a fixed line and a fixed point not on the line.]
Maybe I should have said a "parabolic curve", it does sound better.
Anyway, thanks to everybody for the information. I will try out the
TAChart component.
Regards,

PS: I like your ASCII chart. Pretty good!
