Daily data interpolation distributes the value of a weekly data point across the seven days in the past week. This makes it easy for you to compare daily and weekly data sources everywhere on Next Big Sound. We label any interpolated values with a “W” and define these values as “approximated.”
When graphing, interpolated daily values are displayed alongside daily data values. You’ll see a tell-tale pattern of plateaus when you’re graphing interpolated daily values.
We default to a weekly time interval in our graphing tool when viewing weekly data sources. We switch to this default even if — especially if! — you’re comparing weekly and daily data sources. In this case, it makes it much easier to see and understand patterns in weekly and daily data. You can always override this default to dive deeper into your data. The table below our graph displays approximated values, no matter the time interval selected.
When the weekly time interval is selected, . This is the most common reporting interval for weekly data. Weekly data points from weekly sources will be displayed on the dates that they are reported. This way, you can see weekly trends as clear as possible. The weekly time interval selector replaces our old smoothing transform.
