PetscDrawBarCreate#

Creates a bar graph data structure.

Synopsis#

#include "petscdraw.h" 
#include "petscviewer.h" 
PetscErrorCode PetscDrawBarCreate(PetscDraw draw, PetscDrawBar *bar)

Collective over draw

Input Parameter#

  • draw - The window where the graph will be made

Output Parameter#

  • bar - The bar graph context

Notes#

Call PetscDrawBarSetData() to provide the bins to be plotted and then PetscDrawBarDraw() to display the new plot

The difference between a bar chart, PetscDrawBar, and a histogram, PetscDrawHG, is explained here https://stattrek.com/statistics/charts/histogram.aspx?Tutorial=AP

The MPI communicator that owns the PetscDraw owns this PetscDrawBar, but the calls to set options and add data are ignored on all processes except the zeroth MPI rank in the communicator. All MPI ranks in the communicator must call PetscDrawBarDraw() to display the updated graph.
