I have an issue with the TOPN method.
I have a table with a few columns with different Water parameters, they were filled in on different days (so they have gaps) "InsertDate" column shows these dates. it is also based on different tanks.
Tank | InsertDate | HardnessF | Alkalinity | ph | Conductivity | Temperature |
111 | 13-03-24 11:14 | 25.54 | 6.88 | 808 | 15 | |
111 | 12-03-24 9:27 | 26.07 | 6.94 | 807.2 | 15.3 | |
111 | 11-03-24 10:42 | 24.29 | 2.96 | 6.97 | 803.5 | 15.6 |
112 | 11-03-24 10:40 | 24.29 | 2.96 | 6.97 | 803.5 | 15.6 |
112 | 11-03-24 10:34 | 22.9 | 1.73 | 7.05 | 511.9 | 11.5 |
112 | 11-03-24 10:30 | 26.3 | 2.97 | 6.94 | 831.9 | 15.4 |
112 | 11-03-24 7:15 | 7.772 | 11.9 |
I made a Line charts which show me a trends of value for every parameter based on Insert date. and two slicers for user: "InserDate", and "Tank" to select each tank.
ISUEE: I would like to measure the +/- 3sigma value for each parameter based on only last 10 samples, independently/without the "InserDate" slicer but I can't handle how to remove a filter from this "InserDate" column only for TOPN method.
Hi @PijanMac ,
You can try the following DAX:
Rank =
RANKX( FILTER(ALL('WaterData'),'WaterData'[Tank]=MAX('WaterData'[Tank])),CALCULATE(SUM('WaterData'[HardnessF])),,DESC)
+3sigma_HardnessF_last10samples =
IF(
SELECTEDVALUE('WaterData'[Location])="Poland",
CALCULATE(
AVERAGE('WaterData'[HardnessF])+
3*STDEVX.P(
FILTER(ALL('WaterData'),
[Rank]<=10),[HardnessF])))
