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.
