>scale and show all signal identified on the schematic with test points.
How do I tell the graphs where I want to see the signal?
Say for the basic diode rectifier with resistor. How do I tell it to
show the voltage over Diode 1 or Diode 4 or Resistor 1?
I tried alt-click on the resistor, no differences.
The graphs only tell me some cryptic v[i] thingy
I get three lines on the graphs despite having only one test point
right smack over the resistor.
And there's the perpetual warning about having no ground. The AC Sine
wave generator doesn't have three prongs like my plugs at home does.
Adding a ground anyway doesn't seem to change a thing.

Yup, I switched to TR instead of AC, and I finally got
something on the AC graph, something that starts from negative then
dips then become a hmm.. I dunno inverse? negative? exponential? log?
curve never quite reaching the y-axis.
The DC remains forever a straight sloping line. Though
removing the resistor gives me three lines instead.. ???
Could you possibly include a simple AC/DC circuit in your next
update and maybe I could figure out how this whole spicy thing works
