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, - Graeme - PS: I like your ASCII chart. Pretty good!
