[Gnuplot-info] Problems generating multiple plots using stdin

[Kevin O. <rko...@gm...>]

I am baffled by a failure I am having in attempting to generate a series of
plots on a single image. The inputs are from stdin. I get only the first
and last of the five plots, although the titles for all five are shown. No
errors reported.

I have recorded the stream sent to gnuplot and can see no problems, though
I suspect I am missing a simpler way to do it.
set term gif small size 800, 600
set grid xtics ytics;set xdata time
set colors classic
set timefmt "%H:%M";set xrange ["00:00":"23:45"]
set title "Temperature"
set format x "%H:%M"
set output "/usr/local/www/data/rain.gif"
set ylabel "Degrees Fahrenheit"
plot "-" using 1:2 title "2016-01-01" with lines, "-" using 1:3 title
"2015-12-31" with lines, "-" using 1:4 title "2015-12-30" with lists, "-"
using 1:5 title "2015-12-29" with lists, "-" using 1:6 title "2015-12-28"
with lists

All lines are newline terminated and this is immediately followed by the
data with the data for each plot. It's actually the same data five time
with a different column used each time. Here is the final few lines of the
96 lines.
21:00  14.3    16.5   15.8   12.8   11.6
21:15  14.1    16.6   15.6   12.5   11.8
21:30  14.1    16.5   15.8   12.2   11.4
21:45  13.8    16.3   15.9   12.1   11.2
22:00  13.9    16.4   16.0   12.0   11.5
22:15  13.7    16.5   15.8   11.7   11.6
22:30  13.7    16.4   15.7   11.5   11.6
22:45  13.5    16.4   15.8   11.4   11.2
23:00  13.5    16.2   15.6   11.6   11.2
23:15  13.5    16.3   15.5   11.6   11.1
23:30  13.5    16.3   15.7   11.7   10.7
23:45  13.3    16.2   15.5   11.7   10.5
e
00:00  13.5    16.3   15.3   11.8   10.5

I m doing it this way because in some cases I include a date along with the
time and it change for each plot. I can handle this with a simple
substitution if the data array much more efficiently than I could re-write
a file.

Can anyone point out what I am doing wrong?
