This zooms the graph to the space inside the ``Selection box''. It fits either
the height or the width of the box to the space inside the graph window, but
does not re-scale the window. Thus some extra space will be added either at the
sides or the top and bottom. This function differs from the Zoom in and
Zoom out functions discussed in Section ![[*]](crossref.png)
in that it
cuts out the necessary section, rather than enlarging the complete graph.
