[Gnuplot-info] every cannot read block

[Jon <dev...@gm...>]

Hi guys,

I had supposed I understood the concept of block, but it turned out I
cannot make the following file correctly read in by the command plot.
Thanks for your timely help,

Sincerely,
Jon

========================

The script is

p [0:] 'DY_SLICE_HIST_1'  \
     u 1:2 ev :::1::1 w lp, \
   0 w l lt 0 noti

========================

The error message is:

Warning: empty y range [0:0], adjusting to [-1:1]

The data file is:

The problem is that you have too many blank lines in your data.  The 
separation between blocks to be referenced by `every' is _one_ blank 
line, not six.

Multiple consecutive blank lines create the separation used by "index".

Thanks, it seems I confused about index and every.

Sincerely,
Jon
