Standard Deviation

hello,

 

am new to power BI, and am trying to plot a levey jenning standard deviation chart on power BI, that shows a minimum of 20% and max of 30% deviation from both ends of the ideal concentrataion(ideal concentration varies from 2-2000 in no particular order) and also having the ideal concentration line constant on the gragh when ever an ideal concentration is selected from the slicer. below is a sample of my data which as the calculated concentration on the y axis and the sample on the x axis.

Re: Standard Deviation

Well, I was thinking something like:

 

Ideal = AVERAGE([Ideal Concentration])

Ideal20%Above = [Ideal]*1.2

Ideal20%Below = [Ideal]*.8

Re: Standard Deviation

Well, I can imagine a measure that uses HASONEVALUE and if so, displays the AVERAGE, MAX or MIN of Ideal Concentration. You could then have 2 additional measures for 20% above and 30% below, or whatever, of this measure. Then you just display then in the line chart and they would come out as constant lines.

Re: Standard Deviation

thank you so much for the answer, i also have a situation that i would like to implement a flag if any of the sample concentration exceeds 30% above and 30% below an email should be sent notifying me of the sample that is out of range. thanks you
