# Progress Base

In xViz Gantt Chart, the Progress Base data field is used to calculate the Progress% using the Progress data field.

Let's understand how the Progress Base data field works with an example.

In the xViz Gantt Chart, the Progress % is calculated by dividing the "Progress" data field by the "Progress Base" data field.

In the image below, you can see the DAX calculation, which divides the "Progress" column by the "Progress Base" column.

As a result, the DAX measure provides the Progress % for each task. The image below shows that the Progress % for each task is same in the xViz Gantt Chart and the Table visual.
