Create a data blend and select Edit Primary Aliases to replace the primary data source alias values with values from the secondary data source.

You can then right-click the Dorm_Name field in the Data pane and select Replace References to point to Dorm_Name_New. This method maintains the integrity of the original visualization while simplifying the update process, avoiding the creation of unnecessary calculated fields.

Question 5 of 214

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. Both charts will use the same measure named Population on the axis.
You need to configure the shapes to be much larger than the line.
What should you do?

Duplicate Population Drag the duplicate to the second Marks card and configure the size of the marks independently

For the second axis, select Shape on the Marks card. From Select Shape Palette, select Custom, and then select Reset

Create a custom shape that is larger than the default shape and add the shape to the Shapes folder in My Repository.

Change Population to a discrete dimension.

Correct Answer: A

To create a dual axis chart with independently configured shapes and lines, you should duplicate the measure Population and drag it to the second Marks card. This allows you to configure the size of the marks (shapes) independently from the line chart. By duplicating the measure, you can ensure that the shapes can be made larger without affecting the line chart, which is essential for the visualization you intend to create.
