FacetChart zoom start/end value issue

[gorbunov]

v4.0 pro

I have a chart with a single Facet.
Facet has several FacetValues (of course all have unique Id , but some has the same value "B")

Whenever I use

setZoomEndValue("B");

it sets zoom end to the first "B" value appearance.

Is there any way to control exact end FacetValue to set?
