Which expression should the data architect use to fix this issue?

Exhibit.

A chart for monthly hospital admissions and discharges incorrectly displays the month and year values on the x-axis.

The date format for the source data field "Common Date" is M/D/YYYY. This format was used in a calculated field named "Month-Year" in the data manager when the data model was first built.

Which expression should the data architect use to fix this issue?
A . Date(MonthStart([Common Date]),’MMM-YYYY’)
B . Date([Comraon Date],’MMM-YYYY’)
C . Date(MonthsStart([Common Date]),’VMM-YYYY’)
D . Date(InMontht[Common Date]),’MMM-YYYY’)

Answer: A

Explanation:

The issue described relates to the incorrect display of month and year values on the x-axis of a chart. The source data has dates in the M/D/YYYY format, and a calculated field named Month-Year was created using this date format.

To correct the issue:

The correct approach is to use the MonthStart() function, which returns the first date of the month for the provided date. This ensures consistency in month-year representation.

The Date() function is then used to format the result of MonthStart() to the desired format of MMM-YYYY (e.g., Feb-2018).

Explanation of the Correct Expression:

MonthStart([Common Date]): This ensures that all dates within a month are treated as the first day of that month, which is critical for accurate monthly aggregation.

Date(…, ‘MMM-YYYY’): This formats the result to show just the month and year in the correct format.

Using this expression ensures that the x-axis correctly displays the month-year values.
