== How to use dx ==Run <code>dx</code>, and then in the '''Data explorer''' or '''DE'''.* Click on <code>Edit Visual Programs...</code>.* Select the <code>map.net</code> program created by relax, Now in the <code>Visual Program Editor</code> or <code>VPE</code>.* Select the menu entry <code>Execute->Execute on change</code>. 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 <code>Isosurface elements</code>.* 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 <code>File -> Save image</code> in the <code>Surface</code> window, <code>allowing rendering</code>, and outputting to a large TIFF file, <code>save current</code>, then <code>apply</code>. 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. [[Category:SoftwareOpenDX]]
