Gnuplot barchart histogram with errorbars

Question

I want to the results of my benchmarks. I compare two virtual machines with each other and have data of the following form:

BENCHMARK VM1_TIME VM1_ERROR VM2

Answer 1

Ok, now here's what i got with a little changed version of androverso.

using this code:

reset
fontsize = 12
set term postscript enhanced eps fontsize
set output "bargraph_solid_state.eps"
set style fill solid 1.00 border 0
set style histogram errorbars gap 2 lw 1
set style data histogram
set xtics rotate by -45
set grid ytics
set xlabel "Benchmarks"
set ylabel "Relative execution time vs. reference implementation"
set yrange [0:*]
set datafile separator ","
plot 'bm_analysis_results.dat' using 2:3:xtic(1) ti "Rapydo" linecolor rgb "#FF0000", \
'' using 4:5 ti "R reference implementation" lt 1 lc rgb "#00FF00"

on this data

sort, 2.5953, 0.0013, 1.0000, 0.0034
binary search, 2.8434, 0.0132, 1.0000, 0.0037
sqrt, 2.8675, 0.0022, 1.0000, 0.0079
arithmetic, 1.9187, 0.0020, 1.0000, 0.0036

Maybe someone will find this useful. Thanks again, androverso!
