I have a spreadsheet where I am keeping track of several statistics on a daily basis.

I have another spreadsheet where I am keeping track of several statistics on a weekly basis.

I want to graph the data together. In order to do this, I want to aggregate the first (daily) set of data into weekly data. This will enable to me to get it all on the same graph so I can better visualize it.

Suggestions?

Figured this out, finally. Thanks, community!

I created a table with weekly dates. Then I added summary columns for the daily data:

=SUMIFS(
  column_I_care_about_from_daily_spreadsheet,
  date_field_in_daily_spreadsheet, ">="&date_in_this_spreadsheet, 
  date_field_in_daily_spreadsheet, "<"&date_in_this_spreadsheet
)

I then added a "summary" column to match the weekly data

=SUMIF(
  date_field_in_daily_spreadsheet,
  "="&$date_in_this_spreadsheet,
  column_I_care_about_from_daily_spreadsheet
)

Two things: - Yes, the second formula is overkill - Yes, SUMIF and SUMIFS reverse their fields from each other

From here, I could easily get a graph.
