Hi All,
I am trying to create a control chart using power bi.
I have the date column in my data table name "Date". I have the parameters in another column (oil variance)
So to create the average line, I use this calculation:
The navy blue line it self shows correct number, so when I choose April it shows average of April, when I choose July it shows average of July.
What I want is, when I choose the slicer, the axis date will adjust themselves to only the selected month (before average line was there, it do what I want).
I try to modified the calculation to:
Average Oil Variance = CALCULATE(AVERAGEX(DATA[Date],DATA[Oil Variance]),ALLSELECTED(DATA[Date]))
But it give error
Any idea how to overcome this?
Thanks in advance.

Solved! Go to Solution.
Hi @Anonymous ,
According to the error message, the averagex function returns the average value of the expression calculated for each row in the table, AVERAGEX (<table name>, <expression> ). "Table name" is a table that uses expression to evaluate each row: "Expression" is an expression that is evaluated for each row of the table. Refer to the following formula.
Average Oil Variance =
CALCULATE (
AVERAGEX ( 'DATA', DATA[Oil Variance] ),
ALLSELECTED ( DATA[Date] )
)
If the problem is still not resolved, can you provide an effective data model (delete sensitive information), I will answer you as soon as possible.

Hi @amitchandak
Thank you for your reply. I try your solution and it gave me this error
I think its coming from the Data[Date] As i have date as column in my data table. I really new to power BI so I am not quite sure if I doing it right.
Do you have further advice?
Thanks in advance.

@Anonymous , Is the axis is drived from DATA[Date], I doubt that.
I think it is using date or calendar table.
If yes use ALLSELECTED(Date[Date])
