Re: question about binary plot data

I almost see what is happening now.

outd.data is exactly 10 floats long (40 bytes)

cat test-2.gp outd.data out.data | gnuplot  WORKS
cat test-3.gp outd.data out.data | gnuplot  WORKS
cat test-4.gp outd.data out.data | gnuplot  FAILS
cat test-4.gp outd.data out.data outd.data | gnuplot  WORKS

This is passing strange.  I am attaching my files.
