You need to show the relationship between Total Cost and Total Sales over time.
What should you do?

A. Add a play axis.

B. From the Analytics pane, add an Average line.

C. Add a slicer for the year.

D. Create a DAX measure that calculates year-over-year growth.








 

Suggested Answer: A

When to use a slicer -
Slicers are a great choice when you want to:
Display commonly used or important filters on the report canvas for easier access.
Make it easier to see the current filtered state without having to open a drop-down list.
Filter by columns that are unneeded and hidden in the data tables.
Create more focused reports by putting slicers next to important visuals.
Note: Suppose you want your report readers to be able to look at overall sales metrics, but also highlight performance for individual district managers and different time frames. You could create separate reports or comparative charts. You could add filters in the Filters pane. Or you could use slicers. Slicers are another way of filtering. They narrow the portion of the dataset that is shown in the other report visualizations.
