Description Wagner T. Correa 2000-11-26 03:37:19 UTC

Given the following data in p1-5-hist.dat

22.5 5 5
27.5 13 5
32.5 17 5
37.5 8 5
60 12 40

And the gnuplot file:

set xrange [15:85]
set xtics 5
set data style boxes
plot "p1-5-hist.dat"

the gnuplot shipped with Red Hat Linux 7.0 produces the wrong graph:

The gnuplot available as a tarball from
ftp://ftp.dartmouth.edu/pub/gnuplot/gnuplot-3.7.tar.gz
produces the right graph:

Comment 1 Wagner T. Correa 2001-05-28 18:56:32 UTC

I found the bug.  There is a missing break statement in plot2d.c,  line 328.

*** plot2d.c	Mon May 28 14:51:30 2001
--- plot2d.c.orig	Mon May 28 14:51:20 2001
***************
*** 325,331 ****
      case BOXES:
  	min_cols = 2;
  	max_cols = 4;
! 	break;
      default:
  	min_cols = 1;
  	max_cols = 2;

      case BOXES:

  	max_cols = 4;

      default:
  	min_cols = 1;
  	max_cols = 2;

Comment 2 Wagner T. Correa 2001-06-03 05:32:53 UTC

The problem also happens with the gnuplot shipped with Red Hat Linux 7.1.

ps: I've changed the summary to better explain what the problem was, and I've
included Jakub in the cc list.
