[Gnuplot-info] Histograms with dates on the X axis

[CLOSE D. <Dav...@us...>]

Using the latest release 4.4.0-rc1:

set boxwidth 0.8 relative
set xdata time
set timefmt "%Y-%m"
set format x "%m\\n%Y"
set ylabel "label1"
set y2label "label2"
set ytics nomirror
set y2tics nomirror
set key off
set style fill solid 1.0
set boxwidth 0.9 relative
set style histogram clustered
set style data histograms
set style fill solid 1.0 border -1
plot "/tmp/file" using 2:xtic(1), "/tmp/file" using ($3+$4+$5+$6+$7)
axis x1y2
                                ^
         Need full using spec for x time data

(I understand that some of the settings may not be optimal. For example,
the boxwidth. I would expect to tune these once I see some output.)

A little searching hints that this message may be somewhat misleading.
That what it really means is that a "format" must be added. But perhaps
that hint is wrong? I've tried adding '%lf', '%lf-%lf', and '%lf-%lf
%lf' but the error persists.

Can anyone tell me the right way to generate this plot?
