Can I only plot errorbar except the point in gnuplot?

Question

The error bar looks strange. when I remove the point.

I think this is because the error value is very small

I just want to see the red error bar. How can I do?

1 set term postscrip eps color
2 set output "result.eps"
3
4
5 set errorbars linecolor rgb "red" linewidth 1
6 plot "sigma.dat" using 1:2:3:4 with errorbars pointtype 0, \
7      "sigma.dat" using 1:2 with lines
