How do I display channel Guide Lines in the Scope view?

Two horizontal lines can be set up to act as a visual representation of certain upper and lower thresholds.  These are Guide Lines.  NB these can only be displayed in the Chart View and not the Scope View, where sections of data can be overlayed and averaged.
A workaround for this would be to visualise both the Scope View and the Chart View in the same window.  The horizontal axis can be expanded in the Chart View to visualise individual waveforms and the Guide Lines can be set up here. 
  • Right-click on the Chart View data display area and choose Guide Lines... from the pop-up menu.
The scope view can then be utilised to overlay and average the waveforms as required.
