if the chrt.axis[0].text.items contains more than 55 elements, it will erroneously show only 34 elements

[dev-bre]

I'm encountering this issue with the linechart:

if my chart contains 55 elements on the x axis, everything works great.
if I add another element to the x axis to be shown on the chart,
the chrt.axis[0].text.items.length property will contain only 34 elements!

any idea on the reason?

thanks.
