Computing Distance to go for each axis

I would like to compute the distance to go as a function of each axis. The display in AXIS lists values for DTG for each axis so the data must be available. I did find the pin motion.distance-to-go, but that value is a composite value of all axises, where I want to get the values for each indiviidual axis.

Anyone know where this information is within linuxcnc and how does the AXIS interface get it? I have not checked, but I would guess that the other interfaces are able to access the individual DTG components.

The gui reads it from Linuxcnc.stat. You can read about it a bit here.
linuxcnc.org/lucid/docs/2.6/html/common/python-interface.html

There are probably more info in other programming notes, but that link was the first thing google popped up.
