C# Question

I am working on a scientific calculator in C#. I have the parsing engine and such, now I would like to add a graph so the user can plot a line. Is there any kind of control that will let me input a function and it will graph a line in the chart? I'm not talking about plotting individual points by the way.

Take this linear equation in slope-intercept form for instance:

`f(x) = 2x + 7`

The main goal is to allow the user to write

`2x + 7`

`((x - 8) * 4^2)/(7.136 + x)`

But it's not a requirement. Is there a third-party control for this? If not could someone give me general help on how I would create such a control?

I have downloaded a program that graphs functions like this:

Can anyone help me on how I can achieve this functionality in my Visual C# 2010 WinForms application?

Answer

I searched for `mathematical function plot library for windows`

and found this:

- FPlot a ".NET library for plotting functions and measurement data" (a project on CodeProject)

and you can try to use the source code of:

You'll have to check the licenses. I didn't try any of these, by the way.
