Re: [Gnuplot-info] Plot command with '-' and '' using same data

[Tait <gnu...@t4...>]

The '' syntax re-uses the file name, not the file data. With a normal
file the '' actually re-reads the file again, which is why when gnuplot
goes to re-read from inline you must re-supply the data. To reuse the
file's data, gnuplot would obviously have to cache it, and that is
impractical or impossible for large data sets.

I think I recall some discussion along the lines of implementing a named
data store feature that would explicitly instruct gnuplot to cache a
particular (potentially inline) data set, but I'm not sure whether it
was completed.

To only type in the data once, put it into a regular file with the
appropriate format, and reference it by its file name.
