Scatter Plot of Age

kss5229

I have a smartsheet with many (hundreds) of events. On my dashboard, I would like to display a scatter plot of the age (days) of events as of today. I would like to filter the values, so that only events that are currently open display on the dashboard. I already have a column in my smartsheet with the age of each event calculated.

How are you filtering for open events, with a formula or something else?
