Output on the Interface Tab Gathering data is an important part of modeling Easiest to the Interface Tab Four ways/locations ▫Monitor ▫Graph ▫Command Center ▫Output Area

Output to a Monitor Outputting to a Monitor is easiest.  Requires not in-code output commands  Just need the variable name Outputs the current value of an variable Updated continuously as the model runs

Output to a Monitor Create a Monitor on the Interface Tab ▫Click on the drop down menu (where button is shown) and select Monitor in the drop down menu ▫Add it to the Interface tab clicking on Add and then clicking in the white space ▫The edit dialog box automatically opens

Output to a Monitor

Program with output to a Monitor

Output to a Simple Graph Outputting to a Graph is slightly harder but…  More than one variable at a time  A line for each variable  Graphical information can be easier to understand  History of output Outputs the value of an variable Updated continuously as the model runs

Output to a Simple Graph Create a Graph on the Interface Tab ▫Click on the drop down menu (where button is shown) and select Graph in the drop down menu ▫Add it to the Interface tab clicking on Add and then clicking in the white space ▫The edit dialog box automatically opens
