Line chart to always show latest 52 weeks based on trade this year

[sgaydarska]

Hi,

I need to have the below line chart:

Purpose of visual: show a trend for the last 52 week up to date of trade this year, trade last year and weekly target (only available for 2020)

with the following conditions:

- x-axis will always show 52 weeks back from latest week with trade. E.g. if we're in week 44 2020, the chart should show from week 44 2019 to week 44 2020, when we move to week 45 the chart moves 1 week further week 45 2019 to week 45 2020.

- it should ignore the fact we have target and trade ly values for the whole year and focus on the latest week for which we have trade

- If you select the previous year, in this case 2019, it will simply show you full 2019. 

In my date table I have the following fields available:

key_date	whole number	20010401

year_description	text	2001-2002
id_date_year_start	whole number	20010128
id_date_year_end	whole number	20020202
batch_id	whole number	211

as you can see the majority are whole numbers because I need to use fiscal dates. E.g. Fiscal year 2020 starts on 20200302.

I came accross the following post: https://community.powerbi.com/t5/Desktop/Rolling-52-week-sales-and-preceding-52-week-sales/td-p/7201... but I can't seem to make it work. 

Any ideas?

Thanks,

Hi, @sgaydarska 

According to your description, I guess you want to get a line chart that displays the latest 52 weeks based on trade this year, I suggest you to use the relative date range slicer, which can get the result easily, you can take a look at my steps and find if it’s useful:

This is part of my test data(date range from 2017 to 2020):

1. I created a calculated column to get the Year week:

Week number = YEAR([Date])&"-W"&WEEKNUM([Date])

2. I created a Slicer and change it to “Relative date”-> last 1 year:

3. I created a Line chart and place columns like this:

And I can get what you want.

You can download my test pbix file here

If this result is not what you want, you can post some sample data(without sensitive data) and your expected result.

Hi,

I don't think this works because I need to use fiscal dates which are not "Date" variables. hence I cannot use relative date.

@sgaydarska , the best is to use a relative date slicer. https://docs.microsoft.com/en-us/power-bi/visuals/desktop-slicer-filter-date-range

Or have column like this in your date table

Week Type =
var _date =Today() //or //max(Table[Date]) //max date of table
var _eow = _date+ 7-1*WEEKDAY(_date,2)

Switch( True(),
[start week]<=_eow && [end date]>=_eow -7*45,"45 Weeks " ,
[Week Name]
)

And filter 45 Weeks
