The linear regression layer includes line and point confidence bands as measures of statistical accuracy.

A custom text box is used on the top-left corner to display linear regression parameters.

A chart containing a line layer and a linear regression layer.

Note that the x-axis labels are rotated by 90 degrees so they can be packed more tightly.

A chart with a line layer and a spline layer.

The spline line is computed using the LOWESS algorithm, which is a generic curve fitting algorithm supported by ChartDirector.
