PyX itself needs to fetch this information too. Here is how:

     from pyx import *

     print graph.style.pos.providesdata
     print graph.style.range.providesdata
     print graph.style.histogram.needsdata

BTW: It seems that you do not need to specify the range style  
explicitely to use a non-automatic histogram. This is different from  
what I wrote in the answer to time a few minutes ago. I haven't  
checked, but the histogram tries to get a range by itself ...

Well, there is some documentation in

     print graph.style._style.__doc__

Certainly all this could be improved, but at least it's not that we're  
trying to hide something from our users ...
