With the Reflectance vs. Wavelength graph you can read reflectance and wavelength values for points (one or more points, one or more lines, and one or more polygons), spectrometer readings, and spectra-library signatures in the same graph. The X and Y scales are determined by the variance of the data. You can zoom to a region in the graph window by dragging your mouse over the region you want to enlarge, or by clicking + or - at the top of the window.
Library
Measures radiometric quantities for spectra library samples.
Wavelength (µm)
Measures the wavelength of both the library samples and your source data. The graph shows the unit of measure as wavelength in micrometers (µm) depending on the presence of radiometric transformation metadata in the sample data.
