In the Bottom Panel there is a Plotter, it is ussually hidden until you add a signal to it.
This is done from probes ( see probes tutorial ).

You can add upto 4 sigals from 4 diferent probes, displayed in 4 diferent colors.

There are controls to set the bottom and top voltage of the plotting area.

There is a label Tick indicating the time represented by each division in plotter display.

Plotter runs at 50 Fps at any circuit speed you set, that means you can plot high frequencie signals is you slow down the simulation.

As an example in previous picture there is a plot of a 115 Hz signal, running the simulation at 10000 steps per Sec.
Each division in this case represents 10 mS of circuit time.
