To use the viewer:
1. Select the range of spectra or entire product.
2. Right click the selection and choose Plot Sample Group.
The box to the right is displayed. This dialog is self-
explanatory. In this example, out of the total of 9 spectra
selected, 3 will be displayed, starting from the second
spectrum and displaying every third spectrum. Before
displaying, spectra will be sorted according to time. 2nd
derivative spectra will be shown.
3. Click Colors to choose the color for the group. The
window with spectra stays on top, and the user can
select another group and display it in the same window
with different parameters.
3.4.3 Viewing the Reference Spectrum
Vision automatically stores reference spectra along with sample spectra in a Project database and
allows you to view them. In order to view a reference spectrum that corresponds to a particular
sample spectrum:
• Make sure you are in the Data Acquisition mode.
• Click on the spectrum whose reference you want to view to highlight it.
• Click on Edit/Show Reference.
• Click on the Reference tab in the Spectra window.
• The reference spectrum is displayed.
Spectra imported from NSAS files do not have corresponding reference spectra. In this case
a message is displayed.
