The following commands display the output of simulations graphically, either on-screen or on a printing device. Many take as input a list of vectors or expressions to plot, and in some cases ambiguities may arise. An example would be
plot v(1) -v(2)which would be interpreted as a plot of the difference between the vectors (1 trace) rather than two traces. To resolve such ambiguities, double quotes may be used, as in
plot v(1) "-v(2)"which enforses interpretation as separate expressions. Additional parentheses may also be used to the same effect.
In the expression list, a ``.'' token is replaced with the vector list found in a .plot line from the file with the same analysis type as the current plot. For example, if the input file contained
.tran .1u 10uthen one can type ``run'', then ``plot .'' to plot v(1) and v(2).
.plot tran v(1) v(2)
