Values' Details
NONE
NONE, Description displays no regression curve.
LINEAR
LINEAR, Description displays a linear regression curve. The values of the series are approximated using the model y = A · x + B .
LOGARITHM
LOGARITHM, Description displays a linear logarithmic regression curve. The values of the series are approximated using the model y = A ·log( x ) + B .
EXPONENTIAL
EXPONENTIAL, Description displays an exponential regression curve. The values of the series are approximated using the model y = A ·e B · x .
POLYNOMIAL
POLYNOMIAL, [ DEPRECATED ] Description displays a polynomial regression curve.
POWER
POWER, Description displays a regression curve using a power function. The values of the series are approximated using the model y = A· x B .
