Upper Control Limit in Line Chart with Small Multiple (Wards)

‎05-20-2024 02:59 AM

I am facing challenges with setting an Upper Control Limit (UCL) in my PowerBI Desktop Line chart. My data source is a simple Excel sheet, and I a,m using StartofMonth on the X-axis, Sum of Incidents/1000BedDays on the Y-axis, and Ward in SMALL Multiple. I have two categories: Falls and Injury, and I intend to create two line charts—one for Falls displaying the Falls' Upper Control Limit and one for Injury showing the Injury Upper Control Limit for each ward. However, the UCL I am obtaining is static (I believe it's the average of all wards and not showing the UCL per ward). How can I resolve this issue? I am using. I am using Quartile 1 & 3 way for Limit

Quartile 1 = PERCENTILE.INC(UCL[Incident per 1000 beddays], 0.25)
Quartile 3 = PERCENTILE.INC(UCL[Incident per 1000 beddays], 0.75)
IQR = [Quartile 3]-[Quartile 1]
UCLimit = CALCULATE([Quartile 3] + 1.5 * ([IQR]), ALL())

data set is below: I dont mind if there is any other measure to get the UCLimit like St Deviation method etc as long as I get what I want

Hi, @awsiya 

First, create a measure and calculate the average incidents per 1000 bed days for each ward.

AvgIncidentsPerWard = AVERAGE('Table'[Incident per 1000 beddays])

 Next, create new measure and calculate the standard deviation for incidents per 1000 bed days for each ward.

StdDevPerWard = STDEV.P('Table'[Incident per 1000 beddays])

Then calculate the UCL for each ward. You can adjust the multiplier (in this case, 1.5) based on your UCL requirements.

UCLPerWard = [AvgIncidentsPerWard] + (1.5 * [StdDevPerWard])

 

 Here is my preview:
