A reply to a recent Tableau User Forum Idea, "Option To Place Legend Horizontally Across Bottom For Image And PDF".
This can be done, but not on the worksheet. If you move it
"What I want to show is a YoY (year over year) or WoW (week over week) comparison - however the first data point is always missing - even when the underlying data are available.
The full set of data shows a null value for 2006 - just because there is no data available to compute a comparison.
Now I want to move the date filter to start @ 2007 - and now 2007 has a null value even though we have data available to compute that metric." What's the issue and how can I display only years
Using relative date filters in Tableau dashboards are a great way to keep your dashboard up-to-date with minimal effort. They also provide the consumer with great control if you display the relative date filter as a quick filter on the dashboard, since they enable extensive customization to the time period displayed.
In this dashboard, the current and prior year are displayed. By interacting with the quick filter, you could easily adjust this to one year, two quarters or even two months of data. Give it a try.
