Alternate Views definition
Description
This is where you define what your alternate view is (chart, map, or custom), what it looks like, and what it does.
Clicking the button 
next to the Alternate Views definition property open the Alternate View Builder. The Alternate View Builder has two tabs, a Main View tab and an Alternate Views tab. The Main View tab contains settings that let you define how an Alternate View fits into your grid part. The Alternate View tab allows you to create new Alternate Views and decide on their individual properties.
