Split multiple years date column to multiple lines graph it

[Anonymous]

Hello,

I am a fresh new user and want, from a data set with a column timestamp with multiple years (2015, 2014, 2013...), to produce a graph to compare events between the years.

Any idea on how to do it ?

Please ask if i am not clear

Thank you

Hi @Anonymous 

The best way would be to split your date/time to date and time columns and create a date dimension/calendar table like in the article below.

Can you explain with an example

Timestamp can be converted into date like

Date = table[timestamp].date

Year- format(table[timestamp],"YYYY")

Month Year = format(table[timestamp].date,"MMM-YYYY")

Month Year sort= format(table[timestamp].date,"YYYYMM")

Appreciate your Kudos.

Thank you for your answers !

Here is an example :

TS col	Values
2020/12	5
2020/11	4
2020/10	9
...	...
2019/12	6
2019/11	4
2019/10	2
...	...
2018/12	6
2018/11	7
2018/10	3

I want to print a graph to compare values with a line for each year.

Regards

Hi @Anonymous 

If your [TS col] column can be transformed to "date" type and format as below without any error,

If not, please spilt your [TS col] column as @amitchandak  suggested, or you could split it in power query like the following:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("XcrJCQAgDATAXvYtmMS7Fkn/bWhQIfgcmDkhJBRZEFCg4Zm3szNtj2se51dn/8325bl/v5/fnO0nqC4=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [#"TS col" = _t, Values = _t]),
    #"Split Column by Delimiter" = Table.SplitColumn(Source, "TS col", Splitter.SplitTextByDelimiter("/", QuoteStyle.Csv), {"TS col.1", "TS col.2"}),
    #"Changed Type" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"TS col.1", Int64.Type}, {"TS col.2", Int64.Type}, {"Values", Int64.Type}}),
    #"Renamed Columns" = Table.RenameColumns(#"Changed Type",{{"TS col.1", "year"}, {"TS col.2", "month"}}),
    #"Inserted Merged Column" = Table.AddColumn(#"Renamed Columns", "date format", each Text.Combine({Text.Combine({Text.From([year], "en-US"), Text.From([month], "en-US")}, "/"),Text.From(1,"en-US")},"/"), type text),
    #"Changed Type1" = Table.TransformColumnTypes(#"Inserted Merged Column",{{"date format", type date}})
in
    #"Changed Type1"

Then close&&apply, create a date table, add columns to visuals as below

Prefer to convert it into date

date = Date(left([TS col],4),right([TS col],2),1)

and use time intelligence using date. Totalytd, datesytd etc

YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(('Date'[Date]),"12/31"))
This Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD((ENDOFYEAR('Date'[Date])),"12/31"))

Last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd('Date'[Date],-1,Year),"12/31"))
Last YTD complete Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(ENDOFYEAR(dateadd('Date'[Date],-1,Year)),"12/31"))
Last to last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd('Date'[Date],-2,Year),"12/31"))
Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd('Date'[Date],-1,Year))

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :

I find it really complicated just to split. But as i am a beginner, i guess that's the only way ?!
