How to plot a function in windows forms c#?

Question

C++ / C#

I need to plot the Diocles cissoid function.

Since I do not really understand how to insert this function into windows forms c#, I used the cissoid equation in a rectangular coordinate system:

Here is my code:

public Form1() {
      InitializeComponent();
      int a = 4, m;
      for (int i = 1; i<50; i++) {
        m = (((2 * a) - i) / 2);
        if (m == 0) {
          m = 1;
        }
        chart1.Series[0].Points.AddXY((i), (i*i*i)/m);
      }		
    }

Unfortunately, the result is not at all what is needed:

I think the problem is in how I write the function. Can someone help me solve this?

Answer 1

Duc, and who will extract the root?
And so you build y=x*x*x/(2*ax). By the way, the expression of the denominator is also for some reason divisible by 2.
