To specify or do this... The X-axis format for new spectral windows. Whether to overlay or stack spectra. Whether to be prompted for a window title when a new spectral window is created. The number of panes to use when displaying stacked spectra. Adjust the number of panes in a stack to match the number of spectra. The sampling information to display. The X-axis display limits for new spectral windows. Use this feature... X-Axis Format Spectral Display Prompt For New Window Title Number Of Panes In Stack Adjust Number Of Panes To Number Of Spectra Sampling Information X-Axis Limits Spectral View If you want sampling information displayed with spectra in new spectral windows, turn on Sampling Information. The kinds of information selected in the Sampling Information box will be displayed. See “Specifying the sampling information to display” for details on selecting the kinds of information to display. If you want the X-axis displayed in new spectral windows, turn on Display X-Axis. If you want the Y-axis displayed in new spectral windows, turn on Display Y-Axis. If you want a grid displayed when you display spectra in a new spectral window, turn on Show Grid. The grid is composed of vertical and horizontal lines representing values on the X-axis and Y-axis (see the example below). The major grid lines are aligned with the tick marks labeled with axis values, and the minor lines are evenly spaced between the major lines. The lines make it easier to find X and Y values of points in the spectra. The thickness of the grid lines is always one pixel. 96 Thermo Nicolet
To remove the grid from a spectral window, turn off Show Grid in the Display Setup dialog box. See “Displaying a grid” in the “View” chapter. Note If you want a grid to be printed with spectra or included when you paste a spectrum into a log, turn on Show Grid in the Print options. See “Specifying how to print axes” in this chapter. ▲ If you want the titles of all the overlaid spectra in a new spectral window to be displayed at all times (except for hidden spectra, turn on Display Overlaid Titles. Specifying how to display annotations in new spectral windows Use the options in the Annotation box to specify how to display labels and other annotation in new spectral windows. Turn on Connect To Spectrum if you want new annotations you create with the palette tools to be connected to the spectra with a line. (A label created using Find Peaks in the Analyze menu will always be connected to the spectrum with a line if you move the label away from the spectrum.) See the following example. Turn on X And Y Values if you want to display both the X and Y values of the point you are annotating with the annotation tool instead of just the X value. (You can still edit the annotation after you create it.) See the following example. OMNIC User’s <strong>Guide</strong> 97
