Choose report columns to display
This brings the control to choose which report columns display when embedding reports into a dashboard tile or event type.
If a report lists many columns it is often too much information to display nicely on the dashboard. Within the tile settings for this report you can pick which of the columns you would like to be visible within the tile. Exactly the same control is available when embedding within an event type. The whole report containing all columns is always displayed when viewing the full report.
