You can scroll left or right in the active Chart Analysis window when the amount of data in the chart exceeds the available display of your screen. By default, the scroll bar appears only if data exceeds the available display of your screen. However, you can turn the scroll bars on and off. See Displaying and Hiding the Scroll Bar for more information.
There are three ways to scroll - one bar at a time, one page at a time, and randomly.
Release the mouse button.
