Data Processing

Graphical data can be processed many ways. This section provides information and procedures
for using some of the most commonly used tools.
The user can zoom in on part of a graph to view a particular peak or an area in greater detail in
both spectra and chromatograms. The user can also zoom in repeatedly to view smaller peaks.

Graphs

The same data can be examined in different ways. Data can also be kept for comparison
purposes before performing processing operations such as smoothing or subtraction.
A window contains one or more panes arranged in such a way that all the panes are fully visible
and they do not overlap.
Panes may be of variable or fixed size. Panes are automatically tiled within the window and are
arranged into column and row format. If the size of a window is changed, the panes within the
window change in size to accommodate the new size. A window cannot be sized to the point
where any of the panes would become smaller than its minimum size.
Two or more windows or panes containing similar data can be linked, for example, spectra with
similar mass ranges. As one pane or window is zoomed in, the other pane zooms in
simultaneously.
For example, the user can link an XIC to the BPC from which the XIC was extracted. Zooming in
the BPC also zooms the XIC, so that both chromatograms show the same magnification.
