I'm struggling to get a multi-column bar chart / histogram going with my input as a CSV with headings. As well as the key showing the {wcfiles,wclines,clocfiles,cloclines} attributes.

set style fill solid border -1
set ytics format "%.0s%c" # will generate labels 100k 200k 300k ... 1M
set title 'sloc the Web'
plot '$summary' using 0:2:($0+1):xtic(1) with boxes lc variable,\
"" u 3 title "wclines",\
"" u 4 title "clocfiles"
Check the examples #Ethan mentioned.
In your case you should set logscale y, otherwise it will be difficult to visualize values with differences of several orders of magnitude.

I desgined a histogram in gnuplot however the y-scale needs to be in log2 due to huge difference in values. Therefore, to improve readability of the plot I pretend to display the concrete values on top of each bar. The values represent bytes and so I would like for this values also be in log2 and to be formated to display kb, Mb, ... as is being done in the y-axis.
How can I achieve this?
This is the comands I'm currently using:
set terminal postscript eps enhanced dash color "" 13
reset
set datafile separator ","
set title "Bytes per Protocol"
set xlabel "Protocol"
set ylabel "Bytes" rotate by 90
set yrange [0:1342177280]
set logscale y 2
set format y '%.0s%cB'
set style data histogram
set boxwidth 0.5
set style fill solid
set xtics format ""
set grid ytics
set style data histogram
set style histogram clustered gap 2
set grid ytics
set tic scale 0
set size 1,0.9
set size ratio 0.5
set key autotitle columnhead
set output "ex_a_1_BIG.eps"
plot "ex_a_1_BIG.csv" using ($3):xtic(1) title "IN", \
'' using ($5):xtic(1) title "OUT", \
'' using 0:($3):($3) with labels center offset -2,1 notitle, \
'' using 0:($5):($5) with labels center offset 2,1 notitle
This is the content of the csv I want to plot (I only want the bytes in and out):
protocol,packets in,bytes in,packets out,bytes out
ICMP,1833,141562,979,60334
IGMP,0,0,283,14006
TCP,158214,129221151,130101,47734355
UDP,68476,9571677,72530,24310734
Check help format_specifiers and help gprintf. And the example below.
What is a bit unfortunate, that in gnuplot apparently the prefix for 1 to 999 is a single space instead of an empty string.
For example, with the format '%.1s %cB' this leads to two spaces for 1-999 B and one space for the others, e.g. 1 kB. However, if you use '%.1s%cB' this leads to one space for 1-999 B and no space for the others e.g. 100kB. As far as I know, correct would be one space between the number and the units. I'm not sure whether there is an easy fix for this.
Code:

Result:
Addition:
a workaround for number/unit space issue at least for the labels in the graph would be:
myFmt(c) = column(c)>=1 && column(c)<1000 ? \
gprintf('%.1s%cB',column(c)) : gprintf('%.1s %cB',column(c))
and
plot $Data u 1:2 w boxes lc rgb "green" notitle, \
'' u 1:2:(myFmt(2)) w labels offset 0,1 not
But for the ytics labels I still don't have an idea.
I am working with a histogram in gnuplot and I want to put one of the histogram bars behind the other results. I would like the reference bar (Mörk spennubjögunar > 200 kV) to behind the other histogram bars. I have done this in excel before using different y-axis, is there a nice way to do this in gnuplot?
This is the code I am currently working with.
set terminal pngcairo transparent nocrop enhanced size 3200,2400 font "arial,40"
set output "Harmonic_currents_BRE.png"
set key right
set datafile separator ";"
set style line 12 lc rgb '#808080' lt 0 lw 1
set style line 13 lt 0 lw 3
set grid back ls 12
set xrange [-1:20]
set yrange [0:8]
set style data histogram
set style histogram cluster gap 1
set style fill solid border 0
set border lw 2
set boxwidth 0.7
set ylabel "Hlutfall af nafnspennu [%]"
set xlabel "Tíðni [pu 50 Hz base]"
plot "case0.csv" using 2:xticlabels(1) title 'Tilfelli 0',\
"case1.csv" using 2:xticlabels(1) title 'Tilfelli 1',\
"case2.csv" using 2:xticlabels(1) title 'Tilfelli 2',\
"case3.csv" using 2:xticlabels(1) title 'Tilfelli 3',\
"ref.csv" using 2:xticlabels(1) title 'Mörk spennubjögunar > 200 kV'
unset output
unset zeroaxis
unset terminal
I think, the best way is to first plot the reference with boxes with a fixed boxwidth (I used 0.9), and then the clustered histograms:
set style data histogram
set style histogram cluster gap 1
set style fill solid noborder
set boxwidth 0.7
plot "ref.csv" using 0:2:(0.9):xtic(1) with boxes title 'Mörk spennubjögunar > 200 kV',\
for [i=0:3] sprintf("case%d.csv", i) u 2 title sprintf('Tilfelli %d), i)
I am trying to draw a histogram with broken x-axis. I learnt the basic solution from this post.
However, the x-axis of my histogram is based on strings, not number. It's like this:
set terminal pdf
set output "test-bar.pdf"
set boxwidth 1.0 absolute
set style fill solid 1 border 0
set datafile separator ','
set style data histograms
set xtics nomirror rotate by -45
set ylabel 'Normalized Overhead (%)'
set grid ytics
set yrange [0:10]
plot 'test-bar.csv' using 2:xtic(1) lc rgb "#1E90FF" title ''
And the data is listed like this:
expand , 8.63390441828
cut , 6.84657194596
sync , 6.03615235627
fold , 4.22117995557
nl , 3.54228486647
truncate , 2.66222961714
tr , 2.38357169059
stty , 2.28166797757
users , 2.04211869831
factor , 1.81517270821
tac , 1.790947574
uniq , 1.78799489138
mv , 1.75054704603
mktemp , 1.72228202368
dircolors , 1.6974169738
Right now the plot is in this way:
If I want to leverage the broken axis feature, say, insert the broken between stty and users, how can I do that?
Am I clear enough? Thanks.
Although you use xtic labels from your data file, the xtics are placed at integer x-values, starting at 0. Now, you cannot directly set arbitrary x-values when plotting histograms. You must use newhistogram at ... to shift the second part of the histogram further to the right:
split = 8
plot 'test-bar.csv' using 2:xtic(1) every ::0::(split-1) lt 1,\
newhistogram at split+1,\
'' using 2:xtic(1) every ::split lt 1
Drawing of the upper and lower borders as well as the broken axis signs is done as shown in the post you linked. A possible full script could be
set terminal pdf
set output "test-bar.pdf"
set boxwidth 0.5 absolute
set style fill solid 1 border 0
set datafile separator ','
set style data histograms
set style histogram rowstacked
set xtics nomirror rotate by -45
set ylabel 'Normalized Overhead (%)'
set grid ytics
set yrange [0:10]
unset key
set border 2+8
set linetype 1 lc rgb "#1E90FF"
split=8
dx = 0.125
dy = 0.03
do for [i=0:1] {
set arrow 1+i from graph 0,graph i to first split-dx,graph i lt -1 nohead
set arrow 3+i from first split+dx,graph i to graph 1,graph i lt -1 nohead
set arrow 5+i from first split-2*dx,graph i-dy to first split,graph i+dy lt -1 nohead
set arrow 7+i from first split,graph i-dy to split+2*dx,graph i+dy lt -1 nohead
}
plot 'test-bar.csv' using 2:xtic(1) every ::0::(split-1) lt 1,\
newhistogram at split+1,\
'' using 2:xtic(1) every ::split lt 1
Alternatively, if you don't add or stack more columns, you could use the boxes plotting style, which allows you to use a normal numerical axis.
I could not find a solution to the following issue I am facing. All SO questions on multi-axis talk about line plots, but I am looking for histograms.
The y-range for the bars are different, so one set of bars are not really seen because of the scale. Here is the data:
Metric A B
M1 0.613416301 0.543734744
M2 0.000195961 0.000100190
Here is the MWE:
reset
set term postscript eps size 5.5,4.5 enhanced color font 'Arial-Bold' 25
set out 'histplot.eps'
set key right
set style histogram cluster gap 2
set style data histograms
set style fill pattern 1.00 border
set y2range [0.0001:0.0002]
plot 'histplot.dat' using 2 ti col, '' u 3:xticlabels(1) ti col
quit
This is the sample output (one set of bars over M2 is not seen):
What I prefer is to have a second y-axis (to the right side of the plot) with a range appropriate to the second row of my data file. Is this possible? Any help is greatly appreciated.
Normally you can plot severyl histograms beneath each other using newhistogram. However, it seems like this is buggy when using patterns as fillstyle:
reset
set style histogram cluster gap 1
set style data histograms
set style fill pattern 1.00 border
set yrange [0:*]
set ytics nomirror
set y2range [0:*]
set y2tics
set key right autotitle columnheader
plot 'histplot.dat' u 2 every ::::0, '' u 3:xtic(1) every ::::0,\
newhistogram lt 1 at 1,\
'histplot.dat' u 2 every ::1::1 axes x1y2, '' u 3:xtic(1) every ::1::1 axes x1y2
Alternatively you can use multiplot and plot the two histograms directly beneath each other:
reset
set style histogram cluster gap 1
set style data histograms
set style fill pattern 1.00 border
set yrange [0:*]
set ytics nomirror
set multiplot layout 1,2
set rmargin at screen 0.5
set lmargin 9
unset key
plot 'histplot.dat' using 2 every ::::0 ti col, '' u 3:xticlabels(1) every ::::0 ti col
set rmargin 9
set lmargin at screen 0.5
unset ytics
set y2range [0:*]
set y2tics
set key right
plot '' using 2 every ::1::1 axes x1y2 ti col, '' u 3:xtic(1) every ::1::1 axes x1y2 ti col
unset multiplot
If you don't want the separating black line, you can use set border 7 for the first and set border 13 for the second plot.

'/tmp/data.csv' using 3:2 with points pt 1 lt 1 lc var title "perf_1"
plot x notitle
plot 2*x notitle
plot 0.5*x notitle
obtaining the following error message
"script.gnuplot", line 20: Not enough columns for variable color
Could you please guide me in order to find what I am doing wrong.
By the way the gnuplot version is '4.6 patchlevel 3' the data.csv files used is
0.1,0.1,40.0
0.14,0.14,40.0
0.32,0.32,40.0
0.7,0.74,40.0
Thanks in advance!
That means, that you need to specify one more column in your using statement: The first one is the x-coordinate, the second one the y-coordinate. The one for the variable line color is missing.
Use e.g.
plot '/tmp/data.csv' using 3:1:0 with points pt 1 lt 3 lc var
to use the row number (zeroth column) as linetype index. You can also use e.g. linecolor palette so select the color from the currently defined color palette.
