## Rolling Average visualisation issue Column Chart

Hi All,

I have a problem with the measure of the 3mth rolling average to visualise it correctly on the graph.

The data model is here:

I am using the formula below to calculate 3mth average

Product3Mth = CALCULATE(SUM('Table'[Product A uncum]);DATESINPERIOD('Table'[Date];LASTDATE('Table'[Date]);-3;MONTH))/3

When I am plotting it as a table it is showing right values for each month.

But When I amplotting it in the column chart together with Product A Accumulated I am getting wrong value which is the value for Product unaccum /3 insted of sum of 3 consecutive values for Product unaccum /3.

Take a look.

Hi,

Write this measure and drag it to your visual

=CALCULATE(SUM('Table'[Product A uncum]);DATESINPERIOD('Table'[Date];LASTDATE('Table'[Date]);-3;MONTH))

Hope this helps.

Hi I noticed difference which i have to avoid somehow. It is between the table and the graph visualisation of data.

Please take a look at my data model:

To calculate my Product 3Mth Average I am using the dax below

Product 3 Mth AVG = CALCULATE(SUM('Table'[Product A  uncum]);DATESINPERIOD('Table'[Date];LASTDATE('Table'[Date]);-3;MONTH))/3

It is showing the right numbers when i will place it in the table.

BUT

When I am placing it on the graph it is showing it in this way

How Can I change the formula to present it in the right way. Now it is taking the difference between current month and previous one and divide by 3 which is not what i wanted to do.  Please help

Hi @Anonymous,

I'd like to suggest you use below measure formula if it suitable for your requirement:

```Product3Mth =
VAR currDate =
MAX ( 'Table'[Date] )
RETURN
CALCULATE (
SUM ( 'Table'[Product A uncum] );
FILTER (
ALLSELECTED ( 'Table' );
'Table'[Date]
>= DATE ( YEAR ( currDate ); MONTH ( currDate ) - 3; DAY ( currDate ) )
&& 'Table'[Date] <= currDate
)
)
/ 3
```
