Suppose you have a bar chart. When we group by labels in a view, which of the following happens?

• A.Nothing changes in the view, but a group is created in the Dimensions shelf.
• B.The colours of the members selected are now the same, and different for the rest of the members.
• C.Trick question! It is not possible to group by labels.
• D.A new mark (bar) is created, which consolidates all members of the group.

Correct Answer: D

Explanation
*Very important question*
If we select the labels in the view and then group, a new consolidated mark is created - in our case bar since we are talking about a bar chart in the question. See below:

Using the Time Series table, create a chart that shows the percent difference in Average Inventory on Hand for each Assortment by year and quarter.
How many quarters did the Electronics Assortment show a negative percent difference in the Average Inventory On Hand?

• A.1
• B.2
• C.3
• D.4

Correct Answer: C

Explanation
If you chose 2, then you were very close but probably didn't plot the actual Percent Difference on your view. ( One of the marks is just over the line).
* Firstly, Drop the Week ID onto the column shelf, and convert it to continuous since we need both Year and Quarter as mentioned in the question.
* 2) Next, Drop assortment to filters shelf so that we can focus on Electronics!

3) This should be your view now. Click on the Show Mark Labels icon as shown:
The final view is as follows, with 3 points below 0 ( i.e negative )
