# Creating graphs using Time Tracker

You can use Time Tracker to track the duration incident fields spend on each value.

## About this task

You use Time Tracker to determine how much time a case spends in each value (or collection of values) of a chosen field. For example, you can track how long cases remain in each phase before moving to the next phase.

For simple graphs, you can use Time Tracker by itself without relating it to another field. For more complex graphs, specify one or more fields in the Fields and Time Tracker in the By field. In either case, you must configure Time Tracker, which includes specifying a field to track time and the mathematical computations, such as sum and average.

When Time Tracker is in the Fields area, its values display on the x axis. In the By area, its values are on the y axis.
