Axis values showing incomplete

I have a chat that represents the weekly fulfillment of a budget. In consists
of a line replesenting budget level and weekly I add in a separate worksheet
the orders level for the current week. The thing is that the time axis,
(readsthe values from Budget line sheet) is only showing month and a dash,
but not the year for the months where I dont have orders values.

That is: It's shows "Oct-" for values beyond Sep where I don't have Orders
information where It should be "Oct-05"

Pls help, I have tried every properties for charts but no good results

Thanks, from Argentina
