Add a reference line, band, or box to mark a specific value or region on an axis. For example, if you are analyzing the monthly sales for several products, you may want to include a reference line at the average sales mark so you can see how each product performed against the average. Alternatively you may want to shade a particular area along the axis, show a distribution, or show the full range of values, using a box plot.
Tableau lets you add an unlimited number of reference lines, bands, and boxes. Right-click on an axis and select Add Reference Line, Band or Box to open the Add Reference Line, Band, or Box dialog box:
Reference lines, bands, and boxes are not available when the view is a map using online or offline maps.
