beginners plotting question [message #14390] Wed, 24 February 1999 00:00

Hi -
I'm sorry if this is too basic a question, I just can't seem to find
the answer anywhere.

I'm plotting a data return timeline. I'm forcing the value of good data
to 0 and missing data to 9999, then plotting with a range of +/- 1. I'd
like to mark the start and end of the lines with a symbol of
some kind, like this:

bin 1 |--------------| |--------------------|
bin 2 |------------------------|
bin 3 |---------------------------------|

Is there a first-difference function? I could use that if I could find it,
although I'd also like to skip gaps of less than a certain size.

Any help will be gratefully accespted!
