# PetscDrawLGCreate

Creates a line graph data structure.

### Synopsis

    #include "petscdraw.h"
    PetscErrorCode  PetscDrawLGCreate(PetscDraw draw,PetscInt dim,PetscDrawLG *outlg)

Collective on PetscDraw

### Input Parameters

| draw | - the window where the graph will be made.
| dim | - the number of curves which will be drawn

### Output Parameters

outlg -the line graph context

### Notes

The MPI communicator that owns the PetscDraw owns this PetscDrawLG, but the calls to set options and add points are ignored on all processes except the zeroth MPI process in the communicator. All MPI processes in the communicator must call PetscDrawLGDraw() to display the updated graph.
