Hi... A bit of a newbie, and I haven't figured out something I thought would be basic.
I'm building a dashboard with a visualization of Page Views, Visits and Unique Visitors to a web site by month for the last 13 months.
That part is easy enough to build a nice line graph.
The end user would also like a table below the graph That shows the last 2 months and calculated differences between them.
I started out building a crosstab view on a s2nd sheet that I could add to the dashboard (since it has different date filters than the main chart.)
SO:
August July Variance %difference
Visits 1000 500 500 100%
Uniques 1000 2000 -1000 -50%
Obviously, the last 2 columns are simple in Excel, but I can't figure out how to manage it in Tableau.
Thanks
David
