time series plotting

Hi All,
I'm trying to plot a time series with data gaps. This is I have
something like

X!0="time"
X&time=stamp
stamp_at_units="seconds since 1-1-1970 00:00:0.0"

Most of the data is taken every 30 min, but some times are not
available. The unavailable times do not correspond to _FillValue
values; instead, the time corrdinate just doesn't include those time
stamps. Therefore, if I use gsn_csm_xy to plot the data, a straight
line joins the last point before a gap and the first point after the
gap. I'd like the plot to actually show the gap, for which I imagine
I would have to somehow *insert* the missing time stamps and
corresponding _FillValue values into the time series. Is there an
efficient way to do this in NCL without going through a loop? can I
avoid inserting the missing time stamps at all and still have the
desired effect on the plot?

Thanks much!

James
