What are Shelves and Cards in Tableau?

Every worksheet in Tableau contains shelves and cards, such as Columns, Rows, Marks, Filters, Pages, Legends, and more. By placing fields on shelves or cards, you:

  • Build the structure of your visualization.
  • Increase the level of detail and control the number of marks in the view by including or excluding data.
  • Add context to the visualization by encoding marks with color, size, shape, text, and detail.
