Useful tools for spectral series analysis. a Easy overlay dialog. We developed much simpler tool for spectral overlay than traditional “ol” tool particularly for many spectra. It is activated by two-letter-code “eo”. Simply, user can choose a spectrum “onto” and select spectra to “overlay” by mouse dragging and clicking with Ctrl and Shift keys. When most of all spectra in the project need to be overlaid, user can simply click Select all button and exclude spectra by Ctrl key and mouse clicks. b Change inverse background. We understood the visual limitation of black background color for spectral series analysis if user needs to color spectra differently. Thus, we developed two-letter-code “ci” to change background color from black to white and from white to black. The background color can be set differently and if ornament color is black and white, they are automatically changed to the other color, and so markers such as crosshair are. c Easy contour dialog. This tool is activated by two-letter-code “ec”. It can be used to adjust contour color, level and threshold of multiple spectra all at once
