This dialog simultaneously graphs a single, comparable result or ratio from multiple simulations for comparison. While viewing the Gas Man® Graph Panel , select the horizontal scale from the View drop-down (15 minute view, for example), and scroll to the time period of interest. Then select the Overlay command from the View menu . The variable or ratio selected in this dialog box will be shown for all agents (see Multiple Agent Simulations) in simulations which have both values over the selected interval and open, non-iconic views.
Selecting 'One' in the 'Over' column (as the denominator) will graph a single variable, rather than a ratio, for all the simulations. In that case, the vertical scale will be taken from the Gas Man® Graph that was active when you requested the Overlay view. 'Cost' may be zero if the cost parameters are not set. Selecting 'Cost' in the 'Show' column forces a selection of 'One' in the 'Over' column.
