Using the Trend Plot Screen

For moving-average mid and moving-average end curves, Order is the
range of data points over which moving averages are averaged,
beginning with the first point.

Granularity: Use the Granularity scroll bar to set the granularity of

all curve types except moving-average. The granularity is the number
of “steps,” or straight line segments, making up the curve. Higher val-
ues create smoother curves, but require more drawing time.

The default Granularity setting is 50 curve steps, which gen-
erally creates a smooth-looking curve at a high drawing
speed. Each click to the left decreases the number of steps by
2 (to a minimum of 10), and each click to the right increases
the number of steps by 2 (to a maximum of 1000). With
spline curves, you generally need higher granularity than
normal--up to 10 times the number of points in the graph.
