# PetscSectionSetChart
Sets the range [`pStart`, `pEnd`) in which points (indices) lie for this `PetscSection` on this MPI process 
## Synopsis
```
#include "petscsection.h"   
PetscErrorCode PetscSectionSetChart(PetscSection s, PetscInt pStart, PetscInt pEnd)
```
Not Collective


## Input Parameters

- ***s -*** the `PetscSection`
- ***pStart -*** the first point
- ***pEnd -*** one past the last point





## Notes
The charts on different MPI processes may (and often do) overlap

If you intend to use `PetscSectionSetNumFields()` it must be called before this call.

The chart for all fields created with `PetscSectionSetNumFields()` is the same as this chart.
