From Setup, enter Lightning App Builder in the Quick Find box, then select Lightning App Builder. Click New to create a Lightning Home page, or edit an existing page. Drag and Drop the Report chart component to the Canvas and then select the report .
Or you can create your own dashboard component if you want more custmized dashboard and add to home page component.
We already created an app and used Lightning App Builder. I clicked on recent items and chose object as dashboard .Now the dashboard are coming up un the middle of the screen but once i tried to save it .it is not coming up in the home page.
Or you can create your own dashboard component if you want more custmized dashboard and add to home page component.
