Gnuplot: linespoint with confidence interval

I've following data:

I want to plot a graph shows for all x the mean connected with lines (linespoint) and also showing all the confidence interval [ci_lower, ci_upper]. I managed to do that using 2 plots.

set xrange [0:1100000]
set yrange [0:5000]
plot \
'2011-06-16_1n_result.txt' using 1:7 title '1 node' with lines, \
    '2011-06-16_1n_result.txt' using 1:7:10:11 notitle with errorbars

However it doesn't look nice with two colors and I have the feeling that there should开发者_Python百科 be a way to do that with a single plot.

What's the solution code to that?

I think you are looking for the yerrorlines. Maybe the following example can help you:

Example

Data.dat:

x,   mean,  min,   max
1,   0.40,  0.29,  0.44
2,   0.44,  0.22,  0.65
3,   0.26,  0.06,  0.50
4,   0.30,  0.08,  0.67
5,   0.53,  0.03,  0.88
6,   0.43,  0.08,  0.97
7,   0.37,  0.02,  0.91
8,   0.53,  0.39,  0.60
9,   0.51,  0.22,  0.86
10,  0.55,  0.31,  0.80
