·      Go to View and then to Autorange Y. It will rescale the Y axis.

·      Spectrum is rescaled so all of its Y/X range is displayed.

To examine the details of the spectrum:

·      Go to View and choose Radar Display. Zoom in on a region of spectrum by dragging a grow box in the Radar Display at a desirable band.

·      To close the Radar Display: Display View menu and choose Radar Display.

To view the spectrum status:

                             —Copy: Copies the full status information to the

                                  Window Clipboard.

·      You can view and in some cases update the following things:

                             —Appearance of spectrum

                             —How the sample was prepared

                             —How the spectrums were collected

                             —Number of scans collected

Add text to graph:
