Summary

The Color Spectrum Plot app can be used to create a spectrum curve with filled colors defined by wavelength in x data.

Tutorial

    And three columns for plot data are created in a worksheet. The third column includes RGB values for its wavelength in x data. Colors will be set missing values for wavelength outside the range 360nm to 830nm.
