I'm building a custom map object based off a built-in data table object. In the columns list for the table, I can specify "uptime" as a column, which is cool. My question is what time interval does this uptime column represent, and is there a way to change it? As an example, I would like to show my uptime percentage over the last 30 days in one map, and over the last 365 days in another. Is this possible?
