BigData / Tableau Interview Questions
What is a dashboard in Tableau?
A dashboard combines multiple worksheets, along with text, images, web pages, and interactive controls, into a single unified view — the format most end users actually interact with.
- Worksheets are dragged onto the dashboard canvas as containers and arranged using tiled or floating layouts.
- Filters, highlight actions, and parameter controls can be added so a single dashboard supports cross-filtering between its component worksheets.
- Dashboards can be set to a fixed size, a range of sizes, or a fully automatic responsive layout for different screens.
Dashboard = Worksheet A + Worksheet B + Filter Action + Legend + Text Box
The real power of a dashboard comes from dashboard actions — clicking a bar in one worksheet can filter, highlight, or navigate other worksheets on the same dashboard, turning a set of static charts into an interconnected exploration tool without writing any code.
