Great idea! I say that because I had a similar idea all the way back
in 2004/2005 when I wrote this code ;) Some additional points:
- I also had the idea of letting the user set these themselves,
through a user function argument (a list of number with 4 dimensions).
This can be useful in scripting when you would like a set of OpenDX
maps with all the same contour levels. You might even have a use for
that. For comparisons, this is very powerful.
- The logic needs to be a bit different. You can't use the minimum
chi-squared value as that will not produce a surface. If your minimum
surface is 10, then you need a decent number of points under 10 to
show something. The maximum is the same. Maybe the outer isosurface
could be the value between the highest 10% and the rest. And the
innermost the lowest 10%.
For the middle and inner isosurfaces, you can try this median logic,
but you might find that median of the bottom half of the chi2 values
is better for the middle isosurface. Then the inner could be the
median of the bottom quarter of chi2 points. That's why I have 500,
100, 20, and 7. This is almost exponential. Such a behaviour shows
the space better.

Details:
The current dx.map will have standard values of:
Outer Isosurface = 500.
Middle Isosurface = 100.
Inner Isosurface = 20.
Innermost Isosurface = 7.0
I can take a little time in dx, to find reasonable chi2 values
to map the space.
The idea is to map:
Outer Isosurface = Maximum chi2 value, which is not 1e20.
Middle Isosurface = The median value of chi2.
Inner Isosurface = The median of Middle Isosurface and Innermost Isosurface
Innermost Isosurface = Minimum chi2 value.
This can be done quite easily, by making the
pipe_control.opendx.create_map() collect chi2 values under the creation of
the
map.
Saving the min/max chi2 value, and find the median of all values.
Then pass these values on to the
lib/software/opendx/files.py to write in the .net program.
