Generating Graph Overlays
Use the graph overlay function to compare multiple graph options. Graphical lines are differentiated
by the use of varying colored symbols outlined on a legend. Overlays may be generated in two ways:
• Multiple Sample Overlays - overlay up to 25 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
Only the Advanced format can be used to generate overlays. Go to Options > Options Presentation >
Advanced to access the Advanced format or select Advanced from the dropdown list at the bottom of
the window.
Multiple Sample Overlays
To overlay the same type of graph on multiple samples:
1. Go to File > Open.
2. Select the .SMP file and click Open.
If a file with a status other than Preparing, Prepared, or No Analysis is selected, the isotherm plot
displays. Select Advanced from the dropdown list at the bottom of the window.
When working with an existing file, a copy of the file should be used rather than the
original.
