You have a line chart with the sales amount over the last year. You want to add an average line to the chart to quickly see which months have been above average and which months below average. If that is possible, how can you achieve that? Create a measure using the AVG() function and place it in below the sales amount in the Values area. Create a measure using the AVERAGE() function and place it in the secondary values area. Add the average line by navigating to the Analyze tab and place a measure that is using the AVERAGE() function into constant line area.

Where should you create calculated columns to reduce model size and improve performance? Source data Power Query Data model They all achieve the same results

Source data Creating calculated columns as close to the source as possible helps reduce data model size and improve performance.

You are importing data from a large csv file with 2 million data rows of your support ticket system. The csv file has the following fields: Ticket_id, responsible_id, create_time, solved_time. create_time and solved_time are date/time fields in the following format: 01-01-2022 12:24 What should you do? The solution should minimize the size of the data model but you still need to have access to all the information. Split the columns in two separate fields, one with the date and the other one with the time. Change the data type of the two columns to date to reduce the model size. Change the data type of the two columns to text to reduce the model size. Change the data type of the two columns to time to reduce the model size.

Split the columns in two separate fields, one with the date and the other one with the time. Microsoft recommends splitting up date and time into separate columns for better compression rates. This will preserve all information.
