An interesting problem indeed. I'm no statistician, but I'm thinking some
sort of averaging scheme is needed. I picture an imaginary window over the
time scale that contains past order quantities. The value you would plot
for the centre of the window is a simple average of all the values in that
window. You may want to vary the size of the 'window' depending on how
responsive you want your trend analysis to be: wider window for a smoother
trend curve, narrower window for more of a roller coaster feel. Just some
thoughts from a non-statistician geek type wannabee programmer.
