Control two graphs with one Time Hierarchy

[Bren Croll]

Anyone know how I can control two graphs at once with one custom time hierarchy

I tried some stuff with property controls, by "as column selection" as well as by expression with sort of thing but it didn't work. The graph just dissapears.I would be happy enough controlling theX axis of bothgraphs withjust the one "EventStartTimestampHierarchy". Both are the same, I want thetoline the graphs up and thenwhen the hierarchy is flicked over change the timescale on bothbar charts.

Keeping in mind that the "day" part of the hierarchy is what is keeping the bar graph going left to right properly past midnight (for example without day in the hierarchy 1AM is showing before 11PM).
