Sum

[soha1902]

Hi All,

I have one requirement. In my dashboard I have 1 Dimension Date and 1 measure Values.

Now My Requirement is I want to sum last 30 days data for every date. For example if It is 1 Nov 2015 then it will show sum of 1 Oct 2015 to 31 Oct 2015. if 2nov 2015 then from 2 oct 2015 till 1 nov2015.

Sample File is attached.

use accumulation sum for that.

RangeSum(Above(TOTAL Sum(Measure), 0, RowNo(TOTAL)))/sum(total Measure)

Thanks

Consider using an As Of table:

The As-Of Table

HI,

try some thing like this

Load Date,

         Date(Date#(Date,'YYYYMMDD'),'MM/DD/YYYY') as New_Date,

         Values from Table;

Expression:

=Sum({<Date={">=$(=Date(AddMonths(max(New_Date),-1),'MM/DD/YYYY'))<=$(= Date(max(New_Date)-1),'MM/DD/YYYY')"}>}Value)

You can't easily do that with your current data model. Firstly, your date field is not in a proper date format, so you cannot use normal date functions and date arithmetic to calculate "date - 30 days". Secondly, you will need a date island to use dates as both a dimension and as a row-specific filter.

1. Date functions - load the date using

Month:

LOAD Date#(Date, 'YYYYMMDD') As Date,

    Value

FROM

C:\Users\Desktop\Sheet.xls

(biff, embedded labels, table is Sheet1$);

2. Create a date island. This is a table containing duplicate values of the dates, but not connected in any way with the rest of the data mode.

DateIsland:

LOAD Distinct Date As IsDate

Resident Month;

Now you can use IsDate as the table dimension, and use the expression:

     Sum(If(Date > (IsDate - 30) And Date <= IsDate, Value)

Hi.

Maybe the good way all calculation do in script like below:

Data_01:
