tv-root (see figure 3.1
p. ) is the main graphic-window. By default all
spectra loaded are displayed in this window.
The graphic-window is composed of two subwindows.
The status-window displays the window name as well as the
buffernumbers of the active spectrum, cut, directory and matrix. In
parentheses the buffernumber for the spectrum where the cut is saved
is printed as well as the buffernumber of the projection attached to
the active matrix. In the case that a spectrum is loaded the x- and
y-position are displayed, otherwise questionmarks are printed at the
place of the coordinates. In windows with more then one pane (see
section 4.2.1 p. ) the name of the
currently active pane is displayed.
The lower subwindow or subwindows called graphic-pane(s)
display the spectra and show their according names which are printed
in the upper right corner. In this window you can perform operations
with the mouse as described in section 3.5 on page
. The graphic-pane is surrounded by scales at
all sides which show the counts at the left and right side
(y-scale) as well as the x-position in channels at the top
and energy (see section 4.8 p.
) at
the bottom (x-scale) if an energy calibration is loaded.
The scales are positioned in the frame. The grip is
used to move the line between the status-window and the top frame.
You can switch the y-scale between linear, logarithmic and squared scale with the aliases:
tv lin
tv log
tv qua
You can change the viewport (this is the visible part of the
spectra) in many ways with the hotkeys listed in table
3.1 on page .

Some of these operations can be executed as described in section
