# Baselines

Combine multiple timespans of the same series within one widget using the time-offset setting to compare current data versus data from some time ago.

[series]
  label = today
[series]
  label = yesterday
  time-offset = 1 day
[series]
  label = 1 week ago
  time-offset = 1 week

# Additional Examples

See ATSD Use Cases for other uses for the time-offset setting:

1. California Water Portals

   list ofs = 0, 1, 2, 3, 4, 5, 10
   for offs in ofs
   [series]
     label = @{offs} years ago
     time-offset = @{offs} year
       endfor
   

   

   

2. Tax Day 2018: Americans Reverse the Late-Filing Trend
