The iplot command, available in electrical mode, is useful only if the WRspice program is available. Operation is similar to the plot button, whereby a command string is generated through selection of nodes and branches with the pointer. The command line can be edited in the usual way to generate, for example, functions of the plot variables. Pressing the Enter key saves the command. When the iplot button is active and a command has been saved, the plot is generated dynamically while a simulation, initiated with the run command, is in progress.
Pressing the iplot button a second time will turn off the interactive plotting. Pressing iplot and then Enter will turn the interactive plotting back on. Of course, the trace points and plotting command can be modified before pressing Enter. The trace points are saved along with the file, as with the plot command, so the plotting commands will be persistent.
