Legend

The legend icon under the 'Layers' tab of the 'Advanced' tab can be used as an attachment to a map product that has been printed using the print tool.
 

 
Any layers that are active in the Layers Tab will appear on the Legend.
 

 
Clicking the check box beside Show All Legend Items will put all of the layers that are available in the Layers Tab onto the Legend.
 

 
Once the legend has been finalized, there is the option to open the legend in a new window for easier viewing. The legend can also be printed or emailed depending on if you are sending a map digitally or physically.
