The diode is the device under test (DUT) the two voltmeters are the X/Y inputs of the scope what could I do to improve this circuit I thought the other imput to the scope should do something on the waveform or am I wrong

Just flip the switches to put the components into circuit to test them

Both ends of your top voltmeter are connected to ground. Did you intend this?

I had the meter connected on the wrong side of the resistor I must not have been paying much attention when making this circuit I changed it and now it works like intended and I added a few more devices I can test Thanks for the help

Yes, I know. You're very welcome.

This is a good way of understanding how components react to each other, and differing power supplies. It took me so a bit to understand exactly what you were doing because unless a circuit is laid out, I need to straighten it in my mind. Were you aware that when you highlight a line that it acts as a voltmeter, the only time you need to put a voltmeter on a circuit is to measure the drop across a component. The same goes for an amp meter , highlighting a component will give the current through it.

Yeah I knew that I can highlight a line to see the waveform I kinda did it to show where the scope would connect to I have to visually see how a circuit works which is why EC is great I cant understand a circuit in just a picture I need to see where the current is flowing If I take a circuit off google and make it on a breadboard it never works this way I can see if the circuit will work

For the classic octopus scope XY plot, send one of the voltmeter measurements to the X axis using the eye with the right-pointing-arrow.
