<h1>POW Help</h1>
<h2>Overview</h2>
<p>The main displayed object in POW is a graph. A graph is defined by
a list of curves and images that belong to it. When a graph is
selected (by clicking anywhere within its bounds) a thumbnail
version of the whole graph will be displayed in the <i>scope</i>
window at the upper right showing all of the curves and images that
belong to that graph. The displayed version of the graph, in the
main POW window, lower left, will only display those members of the
graph that fall within the X and Y ranges for the current region of
interest.
</p>
<p>The most important thing to remember when using pow is that all actions,
such as dragging out a region for GTI selection in Xselect, or choosing
a region of interest to zoom in on refer to the currently selected
graph. The currently selected graph is surrounded by a yellow box
in the main POW window, it is displayed in the <i>scope</i> window,
and its name is shown in the yellow box above the scope. So remember
to click on the graph you're interested in before dragging your mouse.
