Analyze g Log 

g ln(y)
Calculates the natural logarithm of every Y value

g 10log(y)
Calculates the 10-based logarithm of every Y value

Analyze g Power

g y..
Calculates y to the power of a value you specify.
This can also be used to take roots: y1/2 = sqrt(y), 
or division: y-1 = 1/y.

g ey
Calculates e to the power of y, the inverse of ln(y)

g 10y
Calculates 10 to the power of y, the inverse of 10log(y)

Analyze g Absolute value of Y

Calculates the absolute Y value of every data point.
