    In This Topic

    A Polynomial trendline creates a curved line, illustrating fluctuations in the data values. The trendline uses the following equation:

    y=b+c1x+c2x2+c3x3+

    where c1, c2, c3 are constants.

    Property Description
    BackwardForecastPeriod Sets a number of periods that the forecast extends backward.
    DetailLevel Specifies if the overlay calculation should include the entire data set or each detail group. Select from Total or Group.
    FieldName Sets the field name for the reference line to use.
    ForwardForecastPeriod Sets a number of periods that the forecast extends forward.
    Intercept Sets the intercept value of Y-axis.
    LegendLabel Sets the legend label of the trendline.
    Order Sets a number of terms in the Polynomial equation. The default value is 2, the value less than 2 is treated as 2, values greater than 6 are treated as 6.
