**Example User Defined Functions** C * X + 51.0 + pi ** e - [Y * A] + B # coefficients are A, B and C |

Scale * exp(X) * exp(Y) + offset # Scale and offset are coefficents in this example |

# the following three examples are equivalent
power(X+Y+shift, C0) # shift and C0 are coefficients in this example
[X+Y+shift] ** C0 # shift and C0 are coefficients in this example
(X+Y+shift) ** C0 # shift and C0 are coefficients in this example |

MXY + B # This fails, it should be written as M*X*Y + B |

**Graph scaling and lin/log control**
Here you can choose the scaling of the data

plots and the 3D scatterplots.

Log plots require data values greater than zero.

X Scale (2D Only) | | Y Scale (2D Only) | | Z Scale (2D Only) |

**Animation and Graph size**
Here you can choose the size of the graphs. Smaller size files load quickly,

with less resolution while large files show more resolution but load more slowly.
