Tableau Desktop Foundations Practice Question

The correct way to create a stacked bar chart from a standard bar chart is to drag a second dimension to the Color property on the Marks card. This action tells Tableau to segment the existing bars based on the members of the new dimension and assign a unique color to each segment, creating the stack.

• Dragging the dimension to the Size property would alter the thickness of the bars for each product category, not stack them.
• Dragging the 'Sales' measure to the Rows shelf is a step toward creating a dual-axis chart, which is a different type of visualization.
• Dragging the dimension to the Detail property would create separate, unstacked bar segments for each category within a region, rather than a single, cohesive stacked bar.
