Yes, you can! If you navigate to the "Admin" section at the top right of your Lineup screen, you will be able to click on the "custom fields" section of that page. Once you've clicked on "custom fields", search for the custom field that you would like to show/hide on your dashboard. Once you've clicked on the specific custom field, if you scroll down to the bottom of that page, you will be able to toggle on or off the "Show chart" switch. Once you toggle it on and refresh your page, it will show up on your dashboard!
