Dear Julia users, I have a rookie question about plotting in Gadfly. I have some density data in a plain-text file in the form of x y d, where d is the density at the point (x,y). I have about 10,000 lines of this data. I'm currently plotting old-school using gnuplot and since I don't like the looks of what I've been able to make, I'm hoping to be able to do something more elegant like Gadfly. I'm a relatively new Julia user as well. I like the "volcano" contour plot from the Gadfly documentation ( second plot from the top at http://dcjones.github.io/Gadfly.jl/geom_contour.html). I'm just not sure how to go about it.
Has anyone done something like this before? I think it could be a really beautiful way to represent my data if I can get it to work. Any hints or suggestions would be greatly appreciated! Cheers, Amelia
