Rolling average without dates

[Anonymous]

I have a dataset that contains batch numbers and cycle times for each batch number. I am trying to create a rolling average over the last 5 batches to plot. Those are the only two variables - I do not have access to dates. I have tried to make an index column of dates, and I have tried other solutions that have been presented on this forum for similar situations including this one, to no avail. 

Any help would be much appreciated.

I found out how to do it minutes after I posted on the forum. I found a calculated column code which works exactly how I want it. 

Column = 
var my_index = 'Table'[Index]
var my_result = 
    AVERAGEX(
        FILTER(
            'Table',
            'Table'[Index] > my_index-5 &&
            'Table'[Index] <= my_index
        ), 'Table'[Parameter]
    )
RETURN my_result

This makes a rolling average of the last 5 parameters. You will need to create an index column, but that's the only thing you should need to create in order to graph a rolling average.

Hi

I'm trying to do something similar, but I'm having trouble following your references.  When you create an index column, do you mean that each record within a batch got the same index number?

What do table Index and table Parameter refer to?  Did you create a separate table just for the index numbers and Parameters is the actual data?

Hi @Anonymous ,

It is very difficult to analyze without looking at the data and just by imagining. Could you please share sample data or sample pbix?(Please mask any sensitive data before uploading)

Can you create a rank column and use?

Rank = rank(all(table),batch,,desc,dense)

last 3 period =

var _max =maxx(table,table[rank])

var _min=maxx(table,table[rank])-3

calculate(sum(table[qty]), filter(all(table),table[rank]>= _min && table[rank]>=_max ))

But move batch to a different table and then do it
