With the Variable Trend you can:

Show trend display curves in a simplified form.
Configure predefined trend display groups (up to 16 trend display curves).
Use control functions to open predefined groups and specific ranges at the click of a mouse button.

This allows you to organize and manage trend displays quickly and easily in any project. There are two default trend display groups that you can either use as they are or customize. You can also create and display your own standard groups for your own projects.
