Add fixed elementIDs to the Detector page
Chuck Brown: "In the hodo displays it omits hodos with zero counts and connects the plot between neighboring points - that is confusing to me and doesn't make it obvious to the user when one of the hodos has 0 counts (or has been turned off on purpose)."
Sylvester has implemented a workaround for this (so that the line / histogram goes to zero).
But it would be best to JOIN the mapping information in the hodoInfo / chamberInfo tables. This requires a fundamental change to the query builder and the detector page.
