Three questions regarding plots in Gretl:


1) Is it possible to do a scatter plot of two variables, with attached marginal histograms next to the corresponding axes, like the picture attached? It would be great if it was possible!


2) How can we get a density histogram without having to have the normal distribution included in the plot. By now, the only way we can get a density histogram (not frequency) is to select to tested against the normal.


3) Observation markers can be easily added to a single, or to all, observations in a X-Y scatter plot, but I do not see how to do the same with X-Y with control.
