# Post Functions - Overview

### Description

Post Functions allow inter-row calculations to be carried out on the rows returned from a raw multi-function profile result set.

### Purpose

Use Post Functions to;

- format data
- plot cumulative graphs
- calculate logarithms
- calculate multi-row averages
- calculate figures for Month-on-Month, Year-on-Year and Year-To-Date
- calculate deltas between rows

### Notes

- Each measure can have a different post-function applied.
- It is not possible to turn off individual post-functions without removing them from the configuration
- The order in which data is returned impacts on most post-processing functions
