Risers from axis or data
Risers are drawn from the X-axis (or XY-plane in 3D charts) to each datapoint. If a Baseline is defined, this is used as the target for the risers, rather than the axis.
sp.LineGraphStyle = LineGraphStyles.Risers;
For polar charts the risers are drawn as radial lines from the centre.
Using risers to show residuals
When a modelfit or trend surface has been used in a Scatter plot or Cloud chart (3D scatter) the risers are drawn from the regression line or fitted surface to each datapoint, rather than from the X-axis or XY-plane.
This provides a quick visual check of the residuals, and may help to locate the datapoints relative to the fitted surface in the projection of the 3D chart.
