In Tableau a hierarchical field is used for drilling down data. It means viewing your data at a more granular level.
What is the Story in Tableau?
A story is a sheet which contains a sequence of dashboards or worksheets that work together to deliver information.
You can create stories to show how the facts are connected, provide context, and demonstrate how decisions relate to outcomes or make a compelling case. Each sheet in a story is known as a story point.
