#25 Need a logical interpolation for the "quotes per day" ogive

[Tim De Pauw]

Right now, the "number of quotes per day" ogive has a
curve that indicates the tendency in the number of new
submissions. The function that describes this curve is
interpolated from the configured number of data points
(default: 3); the data points that are used for
interpolation are selected by dividing the X-axis (i.e.
dates) into equally sized parts. While this technique
can give an indication of progress in quote submission,
I am hoping to find a more logical way of describing
the curve, in order to avoid discrepancies. Suggestions
are most welcome.

Actually, regression/least squares would be a better solution, but this is out of my league. If anyone wants to contribute code or pseudocode, be my guest. :-)
