It is possible to join two or more graphs into a single track. The two (or more) graphs will then have a single track tier label and can be moved and adjusted as a group. To join multiple graphs, select them, then press the Join button in the Operations panel of the Graph tab. To separate these graphs, select the joined track and press the Split button. To switch between the expanded and collapsed state, right-click in the joined track label, and choose between Expand and Collapse.
When the track is in the expanded state, the multiple graphs are shown in separate non-overlapping bands.
