PetscErrorCode PetscDrawHGAddWeightedValue(PetscDrawHG hist, PetscReal value, PetscReal weight)
Logically Collective
Input Parameters#
hist - The histogram
value - The value
weight - The value weight
Notes#
Calls to this function are used to create a histogram with non-integer bin heights. Use calls to PetscDrawHGAddValue() to create a standard histogram with integer bin heights.
This allows us to histogram frequency and probability distributions (https://learnche.org/pid/univariate-review/histograms-and-probability-distributions). We can use this to look at particle weight distributions in Particle-in-Cell (PIC) methods, for example.
