oic....thanks for the clarification.


by the way, i being trying to figure out how to add text to the AnalyticCurve Family to show

dynamically on the plottingpanel.
TS[0] = 1000
TS[1] =
TS[2]=
.
.
TS[9]= 6000

Any tips which text do i used? A 2D text ? or a set of 2D text?

I am having difficulty nailing dynamically [img]http://www.phy.ntnu.edu.tw/ntnujava/index.php?action=dlattach;topic=427.0;attach=971[/img]the position of the text to be at the peak of the function fT

i suspect conceptually, i need to differentiate fT w.r.t. math_failure (math_unknown_error): \lambda \ , equate to zero for the turning point for the highest position PosX, sub back to get the PosY. But i dunno how to do in programming.


the end result is something like this
