How align axis sublabels with there labels

[ev]

I need to have several sublabels for every axis label in my chart.
Every sublable have to be in the new line.
I have created and use MyCategoryAxis extends CategoryAxis (as a copy of ExtendedCategoryAxis with changes)

My createLabel(..) function looks like
...
TextBlock label = super.createLabel(category, width, edge, g2);
...
label.addLine(new TextLine("SUB 1", ...
label.addLine(new TextLine("SUB 2", ...
label.addLine(new TextLine("SUB 2", ...
...
It works fine, I get for example...
LOOOOOONG LABEL
SUB 1
SUB 2
SUB 3
...
Can I get sublabels placed centered to specific label ?
LOOOOOONG LABEL
_____SUB 1
_____SUB 2
_____SUB 3
...
If yes how ?
Thank you !
