Good morning,
I'm having difficulties building a bell curve visualization in Power BI. Want to see this field displayed in a curve to see stddev.
Hi @Hgsilva ,
First of all thanks to parry2k for the quick reply and solution.
Here are the exact steps to follow:
(1) This is my test data.
(2) We can create measures.
Mean = AVERAGE('Table'[Order to Complete TAT in Hours])StdDev = STDEV.P('Table'[Order to Complete TAT in Hours])(3) We can create a BellCurveData Table and create a column on this table.
BellCurveData =
VAR MinValue = MIN('Table'[Order to Complete TAT in Hours])
VAR MaxValue = MAX('Table'[Order to Complete TAT in Hours])
VAR Increment = (MaxValue - MinValue) / 100
RETURN
GENERATESERIES(MinValue, MaxValue, Increment)NormalDistribution =
VAR MeanValue = [Mean]
VAR StdDevValue = [StdDev]
VAR X = BellCurveData[Value]
RETURN
(1 / (StdDevValue * SQRT(2 * PI()))) * EXP(-0.5 * ((X - MeanValue) / StdDevValue)^2)
(4) Create a line chart.
Best Regards,
Neeko Tang
