Labels formatting for Chchart

Hi!
I would be very grateful if u can help me.
have a problem with a proper showing labels for chchart (MO Web component)

Set axCategory = FormYieldCurve.ChartSpace1.Charts(0).Axes(chConstants.chAxisPositionCategory)
With axCategory
.GroupingType = chConstants.chAxisGroupingManual
.GroupingUnitType = chConstants.chAxisUnitDay
.TickMarkUnitType = chConstants.chAxisUnitYear
.TickMarkSpacing = 1
.TickLabelUnitType = chConstants.chAxisUnitYear
.TickLabelSpacing = 5
.Orientation = chLabelOrientationUpward
End With

the idea is - I want ticks to be shown every year but labels - once every 5 years
it works rather ugly:
1) ticks are shown every year = ok
2) labels are shown - once every 5 years = ok
BUT first label is not shown in the beggininh (crossing axis) and the distance between last and previous is much smaller that between others

so it looks like that
spacespacespaceD1spacespacespacespacespaceD2spacespaceD3
instead of
D1spacespacespacespacespaceD2spacespacespacespacespaceD3
