the reddish line should in negative range 1993, 2003 , 2009, isn't. problem, gnuplot fails parse input file or code wrong?

your info file wrong. if closely @ output see, points negative values skipped.

the problem is, instead of having minus sign (u+002d), have en-dash (u+2013), gnuplot fails parse negative numbers, since aren't numbers.

using following, corrected info file

1991 79.09 0 1992 80.61 1.9 1993 79.84 -1.0 1994 81.8 2.5 1995 83.19 1.7 1996 83.84 0.8 1997 85.37 1.8 1998 87.05 2 1999 88.78 2 2000 91.43 3 2001 92.98 1.7 2002 92.99 0 2003 92.32 -0.7 2004 93.41 1.2 2005 94.07 0.7 2006 97.56 3.7 2007 100.75 3.3 2008 101.81 1.1 2009 96.07 -5.6 2010 100.00 4.1 2011 103.59 3.6 2012 103.98 0.4 2013 104.09 0.1 2014 105.76 1.6

does give right output using script:
