Your example isn't complete so it's hard to be sure. But at least part
of the problem is that the last line has a syntax error. It is not
possible to pass two splatted lists to a single function invocation in
this way. (Why not? I don't know. It seems like a reasonable thing to
do. But whatever.)

Instead, try

    g.plot(*(plotlist_pear + plotlist_apple))

; i.e., combine the lists into a single list and then splat the big list
into the function call.

If that doesn't help, then please give us a more complete example,
including what you see and the error output if any.

Yours,
Michael
