You can edit or rename the dashboards that you created yourself. If the current dashboard is not your private dashboard and thus not editable, then a corresponding note appears in the upper dashboard bar.
In the corresponding folder or subfolder, click the "Edit" icon in the Dashboard Explorer.
Now you see "Edit" and "Delete" icons next to each private dashboard.
To rename one of the private dashboards, click the "Edit" icon for this dashboard, and then edit the current name of the dashboard in the text field. Click the "Save" icon now visible next to the name.
To delete one of the dashboards, click the corresponding "Delete" icon of the dashboard from the menu, and then confirm the security prompt with "Yes".
By default, your private dashboards are in the "My dashboards" folder in the Dashboard Explorer.
