For result plots based on a sequence of geometries (IRC/Path, Scan, Optimization, etc.), you may create a plot of a particular molecular property using the Plot Molecular Property... option from the Plots menu at the top of dialog.  You may add as many of these plots as you desire.  Rather than adding new plots, you may also change an existing molecular property to display a different molecular property.  To do this:

• On the molecular property plot of interest, click the right mouse button to bring up its context menu
   
• From the context menu, select Change Plot... to bring up the Edit Molecular Property Dialog
   
• From the main combobox select the desired property type (if different from current)
   
• Change information in the additional fields (charge type, atom indices, or coordinate) as needed
   
• To exit the Edit Molecular Property Dialog, click the left mouse button on the ok button
