For the command colormap (*name::String*[, *n=256*]) *, what values
are available for name::string other than "jet" ?*
*It would be for helpful to have density plot command like the one in
Mathematica. **It would be something like the density(m x n
Array{Float64,2}, n-element **Array{Float64,1}, m**-element **Array{Float64,1})
with a colormap option. **This would somehow cover the shortage of contour
plot and 3D-surface plot for plotting physical fields( temperature,
pressure, ...) over two dimensional space which is very common in physics
and engineering publications.*
*Thank you all JULIA people. *
