I haven't had the smoothest experiences getting plotting in general to work (it's getting progressively better). The plotting in IJulia using PyPlot (matplotlib wrapper) has been good for me.

The Julia plotting packages are Winston, Gadfly, and Gaston. You can find detailed discussions of which one to use on the julia-users mailing list.

Thank you. I can appreciate that it's difficult to implement good interactive plotting, especially across platforms. It's also very very important!
