    I have done a .step (with 4 parameter values) on a .tran simulation.

    When viewing a trace in LTspice (ver. 2.23r) with the expression for ex.:


    all of the simulation steps are plotted with different colors. Ok.

    Then if I plot just one step of the data runs for this node voltage:

    v(N001)@3 for ex.,

    I see a single trace, but on close inspection it appears to be actually
    4 traces overlaid very closely, each displayed in a different color.

    Even wierder, when I plot two steps individually:

    v(N001)@3 for ex.,

    Then each trace appears to be 4 overlaid traces of the same color.
    v(N001)@2 might be 4 overlaid traces in green, while v(N001)@3 appears
    as 4 overlaid traces in blue.

    When a single step selection is plotted along with the set such as:


    Then the individual traces within v(N001) no longer take different
    colors, but are all plotted in the same color.

    Does anyone know what is going on here?
