Description daniel.rentz 2006-06-28 12:26:15 UTC 
New regression curve type "Moving average", that calculates each point on the 
curve as average of the previous N data points, where N can be set by the user.

Example: Chart contains 6 data points, Point1 ... Point6.

Moving average regression curve based on 3 data points will start at Point3 and 
will contain 4 points (Point3 to Point6). For each Point(X) on the curve, the 
average of Point(x-2), Point(x-1), and Point(X) is calculated.

Remember to also add Date support, so that it is possible to get moving average
for the last N days, no matter how many datapoints you have in that interval.
