LTspice includes an integrated waveform viewer that in combination with the schematic editor provides an easy way to display and review simulation data. This means that if you click on an object in the schematic editor, the voltage on that wire or current through that component will be plotted on a waveform viewer and some basic measurements can be taken. This video provides an introduction to the use of LTspice waveform viewer in the analysis of a simple circuit so that you can review edits of your design quickly.
