spectra will overwrite the current spectra. To prevent the current spectrum from being overwritten
in the workspace, click the 'Keep Last Spectrum' button while it is selected.
Spectra can be selected by clicking on their name (selection of multiple spectra is supported
though use of the Shift and Ctrl keys on the keyboard). Selected spectra appear highlighed in blue
and can be removed from the workspace using the 'Delete Selected Spectra' button . All spectra
can be removed from the workspace with the 'Clear All' button .
Only checked spectra are visible on the plot. A checked spectra will have a in the checkbox next
to it's name. Individual spectra can be checked and unchecked by clicking on the checkbox.
Multiple spectra can be checked by first selecting them, and them using the 'Check All Selected'
button . All spectra in the workspace can be unchecked (i.e. the plot cleared) by using the
'Uncheck All' button .
9.2.7 Spectrum Properties
The Spectrum Properties box contains two tabs called 'Spectrum' and 'Data'.
(I) Spectrum
The 'Spectrum' tab contains details of the currently selected spectrum (or last selected spectrum
in the case that multiple spectra are selected). Editable fields are the spectrum name, comments,
and the colour the spectrum appears in the plot. Information fields include the time it was taken,
the device on which it was recorded, and the measurement parameters that were used.
(II) Data
The 'Data' tab shows the numerical data for the selected spectrum. If the spectrum was taken in a
measurement type that requires a background/reference spectrum, the backround/reference
data will also be shown here. The 'intensity' field shows the numerical value after processing, for
example it will show absorbance data if the measurement mode is Absorption. This does not
update while taking continuous measurements.
9.2.8 Status Bar
Shows the most recently completed action, the device status and whether background and
reference spectra have been recorded. The frames-per-second will also be shown here if enabled
in the Tools menu.
9.2.9 Plot Window
All checked spectra in the Spectra Workspace are plotted in this area. Navigation (zooming and
panning) is performed with a mouse. There are 2 options for the mouse interface behaviour: 1-
button mouse and 3-button mouse. This can be selected by right-clicking in the plot area and
selecting 'Mouse Mode' from the menu.
