show weekly change average
Source table:
| ID | Date | WeekNum | Pageview |
| A | Jul 27 2020 | 31 | 100 |
| A | Jul 23 2020 | 30 | 200 |
| A | Aug 4 2020 | 32 | 300 |
| B | Jul 23 2020 | 30 | 333 |
| B | Jul 27 2020 | 31 | 111 |
| B | Jul 27 2020 | 31 | 111 |
Then I created a dynamic table by summarize ():
| ID | WeekNum | Weekly total | % difference vs last week |
| A | 30 | 200 | 0 |
| A | 31 | 100 | -50% |
| A | 32 | 500 | 400% |
| B | 30 | 333 | 0 |
| B | 31 | 222 | -33.3% |
I was able to use Matrix table to show this, but I now want to use avg weekly % change to display with other chart visual like above, how could I extract the 'weekly% change' per ID?
| ID | 31 % change | 32 % change | total (avg) |
| A | -50 | 400 | 175% |
| B | 0 | -33.3% | -33.3% |
i.e. Is there any way to get avg % not using Matrix, and make the 'avg of weekly % change' usage in other chart?
| ID | Avg of weekly % change |
| A | 175% |
| B | -33.3% |
Anonymous - Yes, you can do it all dynamically in variables in DAX. For example here: https://community.powerbi.com/t5/Community-Blog/Design-Pattern-Groups-and-Super-Groups/ba-p/138149
The pattern is:
MinScoreMeasure = MINX ( SUMMARIZE ( Table, Table[Group] , "Measure",[YourMeasure] ), [Measure])
MaxScoreMeasure = MAXX ( SUMMARIZE ( Table, Table[Group] , "Measure",[YourMeasure] ), [Measure])
AvgScoreMeasure = AVERAGEX ( SUMMARIZE ( Table, Table[Group] , "Measure",[YourMeasure] ), [Measure])
etc.You can use something like:
VAR __Table = ADDCOLUMNS(SUMMARIZE(....),"% change", <calc goes here>)
