title: Curve Fitting a data set with unknown formula (SciPy)
body: <p>I'm trying to curve fit a Waldram diagram so that I can plot my own. I used a program and got one curve from the diagram as point data, and want to figure out the formula.</p>
  
  <p>I have a general knowledge of SciPy, and it appears to me that you need to have some sort of idea what the formula of the curve should be, which I do not. Is there a way to solve for a best fit curve without knowing a general formula?</p>
