If you "step" a parameter value, then the step can be referenced in the waveform viewer.
For example, If you want to run three simulations each with a different value for capacitor C1 in a schematic,
Place a statement on the schematic like this:
.step param C list 1u 2u 3u
then for C1, specify the parameter {C} for the value of C1.
The result would be three simulation runs with C1 matching each of the values specified in the ".step" statement for each run.
Then, in the waveform viewer, you can have three plot panes each showing only the result for each step by specifying "@"
for the displayed value. So...if you have a voltage node labeled "out", Click the node so V(out) appears in the plot pane, then change it to read V(out)@1. That specifies you want the value of the first step. Open a new plot plane, click the "out" node again, then change V(out) to Vout@2 to specify the second step, and so on...
