Generating Graph Overlays
Use the graph overlay function to compare multiple graph options. Graphical lines are differentiated
by the use of varying symbols outlined on a legend. Overlays may be generated in two ways:
•
Multiple Sample Overlays -
overlay up to eight plots of the same type with that of the current plot.
•
Multiple Graph Overlays -
overlay two different types of plots from one sample. This type of
overlay is available only for:
– BJH Adsorption/Desorption
– DFT Pore Size/Surface Energy
– Dollimore-Heal Adsorption/Desorption
– Horvath-Kawazoe
– M-P Method
