You can create a brand new dashboard or clone an existing dashboard as a starting point for a new dashboard.
Create a new dashboard
From the Dashboards panel click the Plus + button.
In the New Dashboard window, enter a name for the dashboard. The description is optional.
Select your sharing settings. You can share the dashboard with specific users, assign it to folders and/or generate a link to a view-only version. You can come back to do this later. See Share a dashboard for more information.
Click Save. Proceed to add content to your dashboard.
Clone an existing dashboard
You can clone a dashboard that you own, i.e., one that you created. This is a handy option if you have a dashboard you like but want to change a few things in it. You can then change the content to suit your needs and, if required, share it with other users.
