Settings and Preferences - 1
 Settings control the appearance and behavior of
a chromatogram document, whereas preferences
control the global behavior of Xhromatogram. You
may use Edit|Settings... or the Settings button to
modify the selected document without affecting
any other document. Clicking the OK button will
affect only the current chromatogram document.
Clicking the Make Default button will also make
the new settings the default for the future; in effect
making the current settings into preferences. You
may save these document settings to a file by
selecting File|Save Settings As... then later
selecting File|Open Settings... to retrieve them.
You may also drag and drop a settings file onto the
window.
If there is more than one data trace (for example
mass spectrum and chromatogram) one will have a
a shaded frame to indicate that this one
will have the settings applied to it.
Xhromatogram|Preferences... opens the
Preferences panel. You may set default folders for
opening and saving chromatograms, exported
graphics and document settings.
While many of the options will be familiar to
users of chromatography software, a few do need
further explanation. Most options also have tool
tips that appear after the mouse pointer hovers
over them for a few seconds.
In the General tab, you can edit the caption for
the chromatogram. Elements that are enclosed in
exclamation marks (for instance !experiment_title!)
are replaced by their values from the data file. The
drop-down menu provides the valid variables.
Invalid or missing variables are displayed literally.
Any other text becomes part of the caption.
In the Annotation tab, you can edit peak labels.
Variables enclosed in exclamation marks (for
example !peak_name!) are replaced by data from
the peak table. The drop-down menu will insert
valid variables. Any other text is treated literally.
Identified and unidentified peaks can be treated
separately.
Changing the font in the General tab affects the
entire document, but you may independently set
the sizes for axis units and peak annotations.
