Horizontal Bar Chart doesn't display bar values

Hi everyone.

When I investigated for Horizontal Bar Chart behaviour in ChartsDemo example app, I've noticed two issues:
1. When view controller with HB chart loaded, there are no bar values on it. Tap Options-> Toggle Values hasn't any effect. BUT if we switch on option "Toggle Icons", icons and bar values will appear. So, bar values appear only if icons are switched on. Is this behaviour by-design?
2. Ok, let's assume that Icons are on and Bar Values are on. If I want to scale chart and drag scaled, bar values will also disappear even if they were displayed on non-scaled chart. Is it OK or not?

I've tried to debug pod; something is wrong with chart's renderer and chart's bounds rects.
