Can you post a packaged workbook example (.twbx) or some screenshots?  I believe its pretty common to see a 53rd week, because of additional days in the year (52*7=364 days).

I can't really tell what is 2014 or 2013 in the screenshot--with just WEEK(Date) in the view, your results will be aggregated across all years in the data for each week.

There are several ways you could address this; I'm not sure which is best for your scenario and its difficult for me to explain without a workbook.  One option would be to place a YEAR(Date) pill on the Columns shelf before WEEK(Date), and you'll get a pane for each year.

Even simpler, I believe if your WEEK(Date) pill is continuous, the issue will resolve itself and dates will be displayed.

But again, I do not know the arrangement of the pills in your view--if this does not help, please post a packaged workbook or some more screenshots of the pill arrangement.  Cheers!

If nobody posts a better solution, I'd add a YEAR(Date) pill to the view, so the years are split by panes, as in my first screenshot above.  Of course, if you could color your lines by year, that would resolve your issue as well--but it looks like you're already coloring based on another dimension.

Using Matthew's example, if you right click on the axis and select 'Format' you can edit what is shown for the axis titles.  Put in what you want in the Custom box.  I have put in yyyy "Week" ww here but change to suit.

Very nice.  Thanks Juliette!

Hi Efren

I can't replicate your problem.  Any chance you could post a workbook?
