Hi, sorry...I guess I should have been more clear. I do not know how to edit xaxiis. It rounds it but I'd rather it appear the same as time vector. THANKS

Well, you can't do it that way.
The reason is that 199202 is not a wholly decimal number, which is
what Matlab deals with.
The last two digits are duodecimal, not decimal. They go to 12 before
the 3rd digit from the right increments.

So, you need to convert your numbers to decimal numbers that Matlab
can deal with.
One way is to use Matlab days, see help datenum
Another way is to number in months from the start of the record, then
simply re-label the x-axis ticks to yyyymm format.
