## Main Question or Discussion Point

Hi

I am trying to find a way to create a marginal distribution plot in matlab. I have lots of X-Y values on a scatter plot and need to find the approximate distribution. I have the Statistics Toolbox which is probably needed.

I used POLYTOOL which gives me a mean and standard deviation value for the data on the Y axis, based on a single value for X. Ideally I would want a mean and standard deviation for both though, or at least something that describes the thing as a whole.

This is kind of what I'm looking for:

Any help much appreciated! Thanks
