## Rolling Average on Sprints for total story points covered per sprint

Hi,

I have a table and it contains folowing columns

 Issue Key Product Sprint Name Story Points sprintEnddate Issue Type

I want to calculated the rolling average of total story points completed per sprint for a period of 3 consecutive sprints and sprints are supposed to be arranged in ascending order by their enddate.

Sample table

Here are the steps you can follow：

1. In Power Query -- add Column – Index Column – From 1.

2. Create calculated column.

``````Rank =
RANKX(
FILTER(ALL('Sample table'),
'Sample table'[Sprint Name]=EARLIER('Sample table'[Sprint Name])),[sprintEnddate],,DESC,Dense)``````
``````Index_2 =
RANKX(
FILTER(ALL('Sample table'),
'Sample table'[Sprint Name]=EARLIER('Sample table'[Sprint Name])&&
'Sample table'[sprintEnddate]=
MINX(
FILTER(ALL('Sample table'),
'Sample table'[Sprint Name]=EARLIER('Sample table'[Sprint Name])),[sprintEnddate])),[Index],,ASC)``````

3. Create measure.

``````True =
SUMX(
FILTER(ALL('Sample table'),
'Sample table'[Sprint Name]=MAX('Sample table'[Sprint Name])&&
'Sample table'[Rank]<=4),'Sample table'[Story Points])
``````
``````True  2 =
var _index=
FILTER(
ALL('Sample table'),
[Index_2]=1)
var _table=
_index,"measure",[True])
var _table1=
_table,"result",
AVERAGEX(
FILTER(
_table,
[sprintEnddate]<=EARLIER([sprintEnddate])),[measure]))
return
SUMX(
FILTER(
_table1,
[sprintEnddate]=MAX('Sample table'[sprintEnddate])&&[Sprint Name]=MAX('Sample table'[Sprint Name])),[result])``````
``````Flag =
IF(
[True  2]=BLANK(),0,1)``````

4. Place [Flag]in Filters, set is=1, apply filter.

5. Result:

What would be the expected outcome based on the sample data you provided?

Hi @lbendlin ,

I was looking to plot a line and stacked column chart where on x-axis sprints are arranged in descending order of their completion date and on y-axis we have sum of story points completed during those sprints and a line representing rolling average over the period of 4 sprints(it can be variable).

I am trying to create a measure for that.

``where on x-axis sprints are arranged in descending order of their completion date ``

I think you mean ascending order?

``a line representing rolling average over the period of 4 sprints(it can be variable).``

I am still unclear what you mean by that. Please elaborate.

see attached for the first part. Note that it requires to add the sort column in Power Query as it would result in a circular dependency if it were done in Power BI.

yes, in ascending order(typo),

rolling( moving ) average i.e., sum of story points completed in previous 4 sprints / no. of sprints(4) period could be variable(may increase or decrease),

``Note that it requires to add the sort column in Power Query as it would result in a circular dependency if it were done in Power BI.``

do you mean sorted by sprint?
