Tableau Desktop Foundations Practice Question

When you drag a discrete field, such as a dimension, onto the Columns shelf in Tableau Desktop, how does Tableau visually represent that field in the view and what structure does it add to the worksheet?

It appears as a green pill and creates a continuous axis starting at zero.
It appears as a blue pill and generates evenly spaced column headers corresponding to each distinct value.
It converts to a green pill and shows a gradient color legend for the field's range.
It forms a blue pill that automatically builds a histogram with sized bins.

Answer Description

Discrete fields are rendered as blue pills. Because they represent categorical values, they create a separate column (or row) header for every distinct member rather than a continuous axis. Continuous fields, in contrast, appear as green pills that build axes, color gradients, or continuous headers; they never display as evenly spaced categorical headers. A histogram is produced only when a continuous measure is binned, and a gradient legend is tied to continuous color.

Therefore, the option describing a blue pill that produces individual headers for each distinct value is correct. The other options incorrectly describe behavior associated with continuous fields or special chart-building steps not automatically triggered by dragging a discrete field to the shelf.
