hi,

scatter3 ist really slow here. It's MUCH slower than doing the same
plot in gnuplot.
What's the problem here?



Blame mathworks for considering that each point in a scatter point is a separate patch object.. Then imagine the for loop that Octave needs to have to send all that mess gnuplot.. I don't think there is much to do here for the gnuplot backend though something might be possible with other backends.
