Helper IAverage and StDev lines on different aggregate charts
Hi michaelmichael ,
Could you share a sample Power BI file? That will make it easier to help you.
You can upload your Power BI file to One Drive, Google Drive or other similar tool and share it here.
Let me know,

Helper IPaulDBrown thanks for your help, putting the data into table view, rather than line graph helps.
But when I try your suggested formula for a new measure or column it won't let me use [Standard Deviation of Sub Group Values] as an expression after CALCULATE?
Sorry my formula knowledge is lacking somewhat, but what I'm after is a whole column in this table visual displaying 0.13, and then one with 0.13+StDev of the values
Thanks
Solution SageHi michaelmichael ,
You can find attached an example for the whole column showing the total standard deviation.
Total Standard deviation = CALCULATE(STDEV.P('Table'[Values]), ALL('Table'[x-axis]))
As PaulDBrown mentioned, you can use ALL or ALLSELECTED for that.
This is what it looks like:
Does this help you?

lc_finance PaulDBrown Both, thanks for your help. This does work now, I've got the line across the graph, however the "Total" is not giving me a mean of the values. The mean/average should be 3.08, not 3.29?
From the example above, I've drawn up in Excel what I'm trying to get my table to look like:
