PetscDrawSPCreate#

Creates a scatter plot data structure.

Synopsis#

#include "petscdraw.h" 
#include "petscsys.h" 
PetscErrorCode PetscDrawSPCreate(PetscDraw draw, int dim, PetscDrawSP *drawsp)

Collective

Input Parameters#

  • win - the window where the graph will be made.

  • dim - the number of sets of points which will be drawn

Output Parameter#

  • drawsp - the scatter plot context

Notes#

Add points to the plot with PetscDrawSPAddPoint() or PetscDrawSPAddPoints(); the new points are not displayed until PetscDrawSPDraw() is called.

PetscDrawSPReset() removes all the points that have been added

PetscDrawSPSetDimension() determines how many point curves are being plotted.

The MPI communicator that owns the PetscDraw owns this PetscDrawSP, and each process can add points. All MPI ranks in the communicator must call PetscDrawSPDraw() to display the updated graph.
