The Overlay mode can be activated using the File - Overlay Mode command, double-clicking on the Overlay inscription in the status bar or clicking on the icon. An active OVERLAY mode is indicated by the depressed icon in the Overlay toolbar, highlighted Overlay inscription in the status bar and by the checkmark by the Overlay Mode in the File menu.

Note:

Too many chromatograms opened at once may (especially on slower computers) notably slow down the response of the computer.

In case there is more than one chromatogram (or a chromatogram with more than one signal), it is possible to hide signal by holding CTRL down and clicking on the respective colour in the toolbar. Hidden signals are represented by empty rectangle in the Overlay toolbar (see image below). To once again show the signal, simply hold CTRL down and click on the hidden signal. Alternatively see the Chromatograms topic.
