With this update you can plot one signal versus another. A common example is plotting current versus voltage, aka I-V curve, useful in understanding characteristics of individual components. But if you want to have some fun, use this feature to plot trajectories of oscillators. This Colpitts oscillator by @hurz exhibits a beautiful startup sequence. Flip the switch and wait until the circuit reaches periodic steady-state and the trajectory spirals into a closed orbit. This orbit is called limit cycle. To plot one signal versus another: 1. Add two waveforms to oscilloscope. 2. Select one waveform by selecting corresponding node or component. 3. Click the new button that looks like an eye with x-axis.
