This Chart Macro page at atlassian.com says we can "add the Chart macro to a page to display a chart based on data . . . from an attached file."
The page then explains how to create a chart on a page based on data in a table on the same page, but nowhere does it explain how to create a chart based on data from an attached file, eg, a CSV file. Or am I mistaken?
Perhaps the macro cannot allow you to create charts based on data from an attached file.
