[Gnuplot-bugs] Need full using spec for x time data

[<pl...@pi...>]

Hi,

I have no problem on my main system using time data input driven by .gnu  
files but now I am trying to quickly cast a plot from gnuplot command line  
and it refuses to recognise the data.

[last nights cvs built on ARM]


gnuplot> set timefmt "%H:%M:%S"
gnuplot> show timefmt

         read format for time on x axis is "%H:%M:%S"
         read format for time on t axis is "%H:%M:%S"
         read format for time on u axis is "%H:%M:%S"

gnuplot> show xr

         set xdata time
         set xrange [ "20:00:00" : "20:00:00" ] noreverse nowriteback

gnuplot> set xr ["20:17:00":"20:18:30"]
gnuplot> show xr

         set xdata time
         set xrange [ "20:17:00" : "20:18:30" ] noreverse nowriteback

gnuplot> set terminal svg
Terminal type set to 'svg'
Options are 'size 600 480 fixed  fname 'Arial'  fsize 12 butt '
gnuplot> plot "spew.data"
                          ^
          Need full using spec for x time data


The data file consists entirely of lines like this:

bash-3.2#cat /mnt/nfs/tmpd/spew.data
20:17:24 2.605
20:17:25 2.605
20:17:27 2.607

...

Why is it insisting on a full spec for x time data in the plot command  
when xdata, timefmt and xrange are already set?

Indeed help plot using  indicated I cannot supply a time format in this  
context:

  If a format is specified, each datafile record is read using the C  
library's
  'scanf' function, with the specified format string.  Otherwise the record  
is
  read and broken into columns at spaces or tabs.  A format cannot be  
specified
  this way for time-format data (instead use `set xdata time`).


What have I missed?

TIA, Peter.
