You plan to create a visualization that has a dual axis chart. The dual axis chart will contain a shape chart and a line chart will use the same measure named Population on the axis.
You need to configure be shapes to be much larger than the line.
What should you do?
A. Duplicate Population Drag the duplicate to the second Marks card and configure the see of the marks independently.
B. Create a custom shape that is larger than the default shape and add the shape to the Shapes folder in My Repository.
C. For the second axis select Shape on the Marks card From Select Shape Palette select Custom and then select Reset.
D. Change Population to a discrete dimension
A. Duplicate Population Drag the duplicate to the second Marks card and configure the see of the marks independently.
Explanation:
To configure the shapes to be much larger than the line, you need to duplicate Population and drag it to the second Marks card. This will create a dual axis chart with two measures on one axis. You can then select Shape on one Marks card and Line on another Marks card, and adjust the size of each mark independently using the Size slider or menu.
In a dual-axis chart in Tableau, if you want to have two different visual mark types (like a shape and a line) and configure them differently (such as making one larger than the other), you would need to duplicate the measure. You then drag this duplicate to the second Marks card (which represents the second axis). There, you can adjust the size of the marks (shapes, in this case) independently of the line marks on the first Marks card.
