If you have large arrays with contiguous data you may not want
to concept of NaN or MAXVALUE because you have to *insert*
data into an existing large arry. But as you have the intervals of
good data there is a simple solution. Given your numbers
you have to

Plot, x(0:3), y(0:3)
Oplot, x(4:7), y(4:7)
Oplat, x(8:9), y(8:9)

All you need is a loop which calls Plot for the first segment of
data and oplot for the remaining segments of data.
