This function creates an evenly spaced vector of points in log space.
Math, Utilities
A vector of values, evenly spaced along a log axis.
numpts: in, optional, type=integer, default=10 The number of points desired in the output vector.
double: in, optional, type=boolean, default=0 Set this keyword to return the values as double precision values. Otherwise, floating point values are returned. finish: in, optional, type=float/double, default=100 The ending value of the vector. The output values are evenly spaced between `Start` and `Finish`. This value must be a positive number. start: in, optional, type=float/double, default=1 The starting value of the vector. The output values are evenly spaced between `Start` and `Finish`. This value must be a positive number.
To create 10 values evenly spaced between 5 and 15:: points = cgLogGen(10, Start=5, Finish=150) cgPlot, points, PSym=2, /YLog
