Little help with finding a software graphing package

[dc101]

Anybody knows which package was used to create these? Ultimately, I should also be able to place one or more scatter plots on top of the bottom contour plot. In any case, I don't expect a free one but some reasonably priced would be nice - all suggestions are welcome.

Thanks in advance.

I know you can do these fairly easy in Mathematica and I've also seen some code for it in Matlab.

Here's an example for Mathematica that should work:

nx = 2
ny = 2
Plot3D[
Sin[nx Pi x]Sin[ny Pi y],
{x, 0, 1},
{y, 0, 1},
ImageSize -> '''250''',
BoxRatios -> {2, 2, 2},
AxesLabel -> {x/Subscript[L, x], y/Subscript[L, y], Subscript[ψ, "1,1"]},
PlotRange -> {-1, 1},
TextStyle -> {FontSize -> 96}
]

Thanks loltrader,

I've never used Mathematica. Can you do colored contour plots at the bottom as shown in my example instead of just curves? Can Mathematica also combine more than one plot on the same chart type? What I'm trying to see is two of these (shown below) on the same chart.

It seems that ET does not allow multiple uploads. This is a second one I referred to in my prev post.
