Background Dragging feature is an easy way to scroll the chart horizontally and vertically using the mouse.
To enable click the Background Dragging icon 
on the Main toolbar.
Then drag the chart using the mouse.

When Background Dragging is enabled it is active on all charts in all workspaces.Note 2
If 2 or more workspaces are loaded and Background Dragging is enabled, when one of the workspaces is closed, Background Dragging turns off automatically. The same happens if all charts in a workspace are closed. When MultiCharts is restarted, the Background Dragging is off by default.
