Split multiple years date column to multiple lines graph it
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
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

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.
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 :

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.
