Parameters

seriesName

The name of the series which will be displayed on the chart, i.e. its label.

s

A statistical series.

step

The distance in the x-coordinate between two adjacent extended points. Please note that this also corresponds to the distance in the x-coordinate between the highest and lowest original data point and the first (above or below) additional evaluation point.

forward

The number of additional evaluation points which are evaluated above the x-coordinates of the original given data set.

backward

The number of additional evaluation points which are evaluated below the x-coordinates of the original given data set.

Return Type

A series where the k-th element of the array represents of k-th point (i.e. { x_k, y_k }) of the total set over which the fitted function is evaluated. The total set over which the fitted function is evaluated consists of the `backward' points, original data set points and the `forward' points.

Remark: This methods corresponds in functionality to the method of the same name within Microsoft Excel.
