Question

i have a list values of x-axis value

and i want to calculate y-axis value from any x-axis value of this list

please help me. Thank you

Answer 1

ChartControl API does not include a method to evaluate an arbitrary Spline point value because it uses the GDI+ methods to draw a Bezier curve (see the following ticket for additional information).

In this scenario, it is better to implement a domain-specific function for nonlinear analysis and calculate the required value manually.
