comment handling

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

Hi,

I am getting some inconsistent behaviour from comment handling.

gnuplot> set timefmt "%d.%m.%y:%H:%M"; set xdata time; set ylab "mm Hg" 
; set grid

21.05.12:23:20  96 72  65           # wetday , not walking
22.05.12:09:00                      # rise 9am 81kg
23.05.12:04:30 120 87  49           # work late,bed


help says:

  Comments are supported as follows: a `#` may appear in most places in 
a line
  and `gnuplot` will ignore the rest of the line.  It will not have this 
effect
  inside quotes, inside numbers (including complex numbers), inside command
  substitutions, etc.  In short, it works anywhere it makes sense to work.


However the middle line with the missing data tries to plot the comment !

I'm using a plot that is essentially:

plot datafile using 1:2, '' using 1:3 , '' using 1:4

the first line joins 96 and120 with a straight line.
the second gets a break (this is what I expected for all three)
the last line tries to plot "9am" and so I get a line 65 9 49

All this seems to indicate that it is parsing "#" and "rise" as NaN 
rather than seeing the comment as a comment.

Is this expected? If so the help needs to be changed.

regards, Peter.
