How can I display the difference of simulated and measured spectra?
Sometimes it is advantageous to inspect the difference of simulated and measured spectra in order to find out about appropriate model extensions. Please read the instructions below to activate the drawing of difference spectra.
Open the spectrum for which you want to see the difference with a right-click in the treeview. Select the local menu command File/Options/Difference/Show to turn on the difference display. This menu item is a checked property: Clicking on it changes its status from checked to unchecked or vice-versa.
The additional menu commands File/Options/Difference/Pen and File/Options/Difference/Line mode are used to control the appearance of the difference curve. Use these settings to clearly separate the difference curve from the simulated and measured spectra. You can use, for example, pen 3 (green by default) and line mode 3 (dashed).
