[Gnuplot-bugs] No lines in plots

[Christian L. <li...@pe...>]

Hi,
in gnuplot 4.0, when I try to plot a line plot, I get an empty diagram.
I can plot points and linespoints will just look like points whereas
lines just plots nothing. I have this problem on both Gentoo Linux and
FC3 Linux. However, I'm pretty sure that it used to work on Gentoo
and stopped working without an update of the gnuplot package. I
therefore suspect that this is caused by some library. My gnuplot
binary links against the following libraries.

linux-gate.so.1 =>  (0xffffe000)
lib3dkit.so.1 => /usr/lib/lib3dkit.so.1 (0xb7ee1000)
libvgagl.so.1 => /usr/lib/libvgagl.so.1 (0xb7ed3000)
libreadline.so.5 => /lib/libreadline.so.5 (0xb7ea4000)
libncurses.so.5 => /lib/libncurses.so.5 (0xb7e64000)
libvga.so.1 => /usr/lib/libvga.so.1 (0xb7de9000)
libz.so.1 => /lib/libz.so.1 (0xb7dd7000)
libgd.so.2 => /usr/lib/libgd.so.2 (0xb7d89000)
libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0xb7d6a000)
libfreetype.so.6 => /usr/lib/libfreetype.so.6 (0xb7cff000)
libpng12.so.0 => /usr/lib/libpng12.so.0 (0xb7cdc000)
libm.so.6 => /lib/libm.so.6 (0xb7cb6000)
libpdf.so.5 => /usr/lib/libpdf.so.5 (0xb7ba8000)
libc.so.6 => /lib/libc.so.6 (0xb7a8a000)
libdl.so.2 => /lib/libdl.so.2 (0xb7a86000)
/lib/ld-linux.so.2 (0xb7f07000)

with the corresponding packages (on Gentoo)

svgalib-1.9.25
readline-5.1_p4
ncurses-5.5-r3
zlib-1.2.3
gd-2.0.33
jpeg-6b-r7
freetype-2.1.10-r2
libpng-1.2.12-r1
glibc-2.4-r3
pdflib-6.0.3

I've included the Gentoo revisions but as this problem also occurs on
FC3, I'm inclined to thin that they don't matter. The problem exists at
least with x11, PNG, and PS terminals. Could it be GDlib?

Cheers,
Christian
