Tableau Desktop Foundations Practice Question

Placing a discrete dimension on the Rows shelf and a measure on the Columns shelf tells Tableau to draw one bar for each row member, extending along the horizontal (x-axis) according to the measure's value. Dragging Region to Rows creates separate rows for each region. Dragging the Sales measure to Columns supplies the numeric axis, so Tableau's Automatic mark type becomes a horizontal bar chart. The other options place the fields in different shelves or on the Marks card, which results in vertical bars, a single aggregate mark, or another default view instead of the requested horizontal bars.
