The OpenDX software is a powerful program for visualising multi-dimensional data.

How to use dx

Run dx, and then in the Data explorer or DE.

Click on Edit Visual Programs....
Select the map.net program created by relax,

Now in the Visual Program Editor or VPE.

Select the menu entry Execute->Execute on change.

That's it.

You now have a 3D frame, but nothing in it. Therefore the contour levels must be too low or high. From the map file, the values are in the hundreds of thousands.

Then:

In the main program window, double click on the Isosurface elements.
Change the values until you see surfaces. In the first the value is 500. I changed this to 500,000. Multiply all by 1000.
In the second, 100 -> 100000.
In the third, 20 -> 20000.
In the last, 7 -> 7000.

This should maybe be performed by the dx.map user function, determining reasonable contour levels.

With a bit of zooming, clicking on File -> Save image in the Surface window, allowing rendering, and outputting to a large TIFF file, save current, then apply.

Note that for a good resolution plot, you will need many more increments. Using the lower and upper dx.map arguments will be useful to zoom into the space.
