The Graph Window
Depending on the settings that have been selected, you will see different representations of your waveform in the graph window.
By default, the necessary calculations are applied automatically and the graph is zoomed to encompass only the active region.
You can move the green cursor along the points with your mouse or possibly with
your arrow keys(depending on your Operating System). As you do this, you can
see the absolute data change in the (Absolute) text boxes below the graph. If
you click on the graph(or hit the enter key) the blue circle will be moved to
the selected point. This is the reference circle; it determines what will
appear in the Relative boxes. If more than one graph is open, you can switch
between them using the tabs at the base of the window. The upper text boxes
reflect the header information for a given graph and the lower ones give the
peak details.
