# DMLabelSetValue
Set the value a label assigns to a point.  If the value is the same as the label's default value (which is initially -1, and can be changed with `DMLabelSetDefaultValue()` to something different), then this function will do nothing. 
## Synopsis
```
#include "petscdmlabel.h"   
#include "petscsection.h"   
PetscErrorCode DMLabelSetValue(DMLabel label, PetscInt point, PetscInt value)
```
Not Collective


## Input Parameters

- ***label -*** the `DMLabel`
- ***point -*** the point
