The Radiometric Quantity vs. Wavelength graph allows you to read radiometric and wavelength values for both regions of interest and spectra library signatures in the same graph. The X and Y scales can be adjusted using the Plotting Ranges and Graph Option controls. You can zoom to a region within the graph window by dragging your mouse over the region you want to enlarge.
Library:
Measures radiometric quantities for spectra library samples.
Band Number or Wavelength [nm]:
Measures the band number or wavelength of both the library samples and your source data. The the graph shows the unit of measure as Band Number or Wavelength in nm depending on the presence of radiometric transformation metadata in the sample data. When no transformation metadata is present, the values are shown as band numbers.
