μ Mean (positive).
σ or λ = Parameter: σ or λ = μ3⁄σ2.
xmax, m Graph goes from 0 to xmax (sufficiently > μ), with m points.
Show values Shows the coordinates of the curve.
xp, p A value of x [to get F(xp)], and a probability [to get x = F−1(p)].
  Draws the graph of an “inverse Gaussian” distribution, not to be confounded with the inverse of the Gaussian, or "normal", integral.  The curves for the pdf and, optionally, the cdf are shown.
  The value corresponding to a given cumulative distribution is calculated (via Newton-Raphson).  (If it is p = 1, 0 is assumed.)  Too small σ may obstruct the calculation.
  The formulas are:
