Report settings allow to control various aspects of the report behavior. The settings screen is open automatically when a new report is saved for the first time, and can be open from the gear icon any time when editing a report:
The Report settings are:
Report title - the title for the report
Display title on dashboard - if checked, the title is displayed in the header of the report when viewed on dashboard
Description - an optional longer description, displayed in a tooltip on the report title
Attribution/Copyright - an optional attribution or copyright text, displayed in a tooltip on the report title (in the future will be displayed as an overlay text at the bottom of the report, always visible)
No data label - a text displayed on the report when its query produces no result. By default the text "No data" is displayed
Allow unlimited CSV - allows the additional action "Download CSV (Unlimited)" for the report - see details here: Exporting report data
