Generating a Bestfit Curve

Generate a Bestfit scattergraph curve after editing any required
scattergraph data and setting up the curve parameters. The
Scattergraph Editor generates Bestfit curve coefficients after
vertically segmenting the scattergraph into equal parts (bins) and
averaging the data points within each bin to derive the Bestfit curve
points. The default enables you to generate a Bestfit curve
representing freeflow data points and backwater data points. You
also can display either the freeflow set of data points or the
backwater set of data points separately by clicking (off) the
appropriate Use box.

Generate and display a Bestfit curve for the current scattergraph
