If this optional plot file is present, then all plot planes will automatically be displayed after the "Run" button is pressed, otherwise the user will need to click on each net to see the waveform(s). To create a plot file on Windows, after a plot graph is displayed, right-click on it and choose "File", then choose "Save Plot Settings". The following example for the above schematic shows settings for a "transient analysis" simulation with two waveforms on one plot plane consisting of the RC voltage at "out" net and current through resistor R1, which are labeled V(out) and I(R1) at the top of the plot graph.
