# PetscDrawPointSetSize
Sets the point size for future draws.  The size is relative to the user coordinates of the window; 0.0 denotes the natural width, 1.0 denotes the entire viewport. 
## Synopsis
```
#include "petscdraw.h" 
PetscErrorCode PetscDrawPointSetSize(PetscDraw draw, PetscReal width)
```
Not collective


## Input Parameters

- ***draw -*** the drawing context
- ***width -*** the width in user coordinates
