PetscDrawBarCreate#
Creates a bar graph data structure.
Synopsis#
#include "petscdraw.h"
#include "petscviewer.h"
PetscErrorCode PetscDrawBarCreate(PetscDraw draw, PetscDrawBar *bar)
Collective
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 process in the communicator. All MPI processes in the communicator must call PetscDrawBarDraw() to display the updated graph.
