draws a contour plot for a two-dimensional array

Synopsis#

#include "petscdraw.h" 
PetscErrorCode PetscDrawTensorContour(PetscDraw draw, int m, int n, const PetscReal xi[], const PetscReal yi[], PetscReal *v)

Collective on draw, but draw must be sequential

Input Parameters#

  • draw - the draw context

  • m,n - the global number of mesh points in the x and y directions

  • xi - the locations of the global mesh points in the horizontal direction (optional, use NULL to indicate uniform spacing on [0,1])

  • yi - the locations of the global mesh points in the vertical direction (optional, use NULL to indicate uniform spacing on [0,1])

  • V - the values

Options Database Keys#

  • -draw_x_shared_colormap - Indicates use of private colormap

  • -draw_contour_grid - draws grid contour
