Multiplot on Octave

I have actually lately mounted octave from Synaptic on my Ubuntu box.

To my shock, the multiplot approaches (multiplot, mplot, etc) are absent (in either octave - 3.0 neither octave - 3.2 plans).

Which plan should I install to have these?

I've located plans such as octave - plplot have these features, but also for plplot or various other collections ... I simply desire the gnuplot vanilla variation ...

Thanks beforehand!
