Average X

Hello I'm trying to do a control chart by using the lines graphic. For that I need to add on the graphic a constant line that will be the average of all my results from the column Result of my tab....

    HI matdel ,

     

    In that case you can modify your average caluclation DAX as follows:

    AVERAGE RESULT = CALCULATE(AVERAGE('Quality control results'[Result]), ALL('Quality control'))

     

    You don't have to use AVERAGEX to achieve this. Because it evaluates an expression for each row. You need a single average value for your RESULT column therefore you need to use AVERAGE.

     

    Thanks,

    Pragati

HI matdel ,

 

You can simply add a average line using the Analytics Pane feature on a Line chart visual. You don't need a calculation for it. See an example below:

 

Thanks,

Yes, thanks, but actually after I need also to calculate UCL and LCL from the average, to put them on the graphic also

STDEV RESULT = CALCULATE(STDEV.P('Quality control results'[Result]),ALLSELECTED('Quality control results'[Result]))
UCL RESULT = [AVERAGE RESULT]+3*[STDEV RESULT]
LCL RESULT = [AVERAGE RESULT]-3*[STDEV RESULT]
