Even though all the circuit voltages currents are computed during a simulation, they are not automatically plotted for the obvious reason of avoiding congested and confusing graphs or enormous data tables. Therefore, you have to specify which circuit observables you would like to display at the end of a simulation. At the bottom of each Test Panel, there is a section dedicated to the specification of output results. Two checkboxes labeled "Graph" and "Table" and two buttons labeled "Preset Graph Plots" and "Preset Table Plots" are used to define all the observables to be graphed or tabulated. Both buttons open up the "Edit Plot List" dialog. You can either graph the output data or display them in tables or have it both ways. Note that the graph and table specifications are independent of each other and must be done separately.
The Edit Plot List dialog consists of three tables. The table on the left shows the hierarchy for the case of multilevel signals. In the middle table (Signal Name List) you see a list of the available signals for plotting. The table on the right (Graph Name List) lists the signals to be plotted. Select one of more signals from the middle table and use the right arrow button ("Add-->) " button to move them to the right table. You can also select more than one signal using the "Ctrl" key or a range of consecutive signals using the "Shift" key. You can also may modify and revise the list of the signals to be plotted by moving one or more items from the right table back to the middle table using the left arrow button ("<--)Remove" button.
Besides voltages, currents and powers, [[B2.Spice A/D]] allows you to define, calculate and graph or tabulate new custom plots.
