Hello, I have a bidimensional dataset and have succesfully (with the help of this list btw.) the density of the data with smoothScatter. I have just one other issue: I would like to see that plot "normalized" in the X, that means I would like to have a 2d density plot of Y|X to see where are the critical points for every X point. Should I create a density matrix and then apply some kind of transformation to it or is there a more direct way to plot it? thanks, Francesco Stablum P.S. sorry for my poor english -- The generation of random numbers is too important to be left to chance - Robert R.
