Well, as I said, you edited your .PLT file, which you should not have done.? Don't go there.? That would be like "the blind leading the blind".

But I see this looks wrong:

? ? ? traces: 1 ?{34603010,0,"Id(M1)"} {524291,1,"d(Id(M1))/d(V(Vgs))"}
It says "traces: 1" but then it lists two traces.? That's a mistake.

I'll say this once again:? Do not try hand-editing your .PLT file, in hopes that some magic will happen.? Magic usually does not happen.

Then set up the plots to give you that plot.

So -- what exactly do you want to plot?
