How to represent empty cells on line chart?
I am building a blood pressure spreadsheet and a companion line chart. When I forget to take a reading for a day and have an empty cell the line chart has a break in continuity. Is there a way to continue the line chart from one cell w/data, past an empty cell to another cell with data, and keep the line intact?
