Tableau Desktop Foundations Practice Question

A combined axis chart places two or more measures on the same continuous axis. In Tableau, this is created by dragging the second measure directly onto the existing axis until the cursor changes to a double ruler icon, then dropping it. This action tells Tableau to use the same axis for both measures, typically by employing the Measure Names and Measure Values fields to create a view with a shared scale. Duplicating a pill to the Label shelf only adds text labels and does not build the chart. Choosing Dual Axis creates a separate, second axis for the new measure, which is a different chart type. Moving measures to the Measure Values shelf is the underlying structure for a combined axis, but it is not the most direct drag-and-drop action onto an existing axis as described in the question.
