ChartTrendlineType | A ChartTrendlineType enumeration member that indicates the trendline type. |
Available values:
Name | Description |
---|---|
Linear | Calculates the least squares fit for the line y = m * x + b. |
Logarithmic | Calculates the number of squares that fit for the logarithmic curve y = a * ln(x) + b, where ln is the natural logarithm. |
Exponential | Calculates the least number of squares that fit the exponential curve y = a * b^x. |
MovingAverage | Uses a sequence of averages calculated across each set of N consecutive values, where N is the number specified for the Trendline.Period. |
Polynomial | Calculates the least square fit using a polynomial curve of order equal to the number specified by the Trendline.Order property. The equation is in the form y = b + (c1 * x) + (c2 * x^2) + … + (cN * x^N) where N is the trendline order. |
Power | Calculates a least square fit for a power curve in the form y = a * x^b. |
