I have a graph with two lines. Now I want to mark standard deviation and average for the Y-points. Any idea ?
If I use "errorbars" option, it is not marking stddev or average.
Here is my script to plot graph:
#set xrange [0:]
set terminal png linewidth 2
#set output '| display png:-'
set output "result_macs.png"
set ylabel "Flows/sec"
set xlabel "MACS per Switch"
set grid
set format x "%.0f"
set format y "%.0f"
set style line 1 lt 1 lw 3 pt 1
set style line 2 lt 2 lw 3 pt 2
# put the key (legend) outside, right of the plot area,
# # vertically centered (as in your picture)
set key outside right center
set xtics("1000" 0, "10000" 1, "100000" 2, "1000000" 3, "10000000" 4)
plot "floodlight.data" using :2 title "Floodlight" with linespoints, "beacon.data" using :2 title "Beacon" with linespoints

I would like to plot a histogram comparing DE vs IE and also show error bars (data in column 4) for the IE values.
Please any help on how to go about it.
There is a variant histogram style for exactly that purpose
set style histogram errorbars gap 2 {lw W}.
Here is the help section from the docs:
The `errorbars` style is very similar to the `clustered` style, except that it
requires additional columns of input for each entry. The first column holds
the height (y value) of that box, exactly as for the `clustered` style.
2 columns: y yerr bar extends from y-yerr to y+err
3 columns: y ymin ymax bar extends from ymin to ymax
The appearance of the error bars is controlled by the current value of
`set errorbars` and by the optional <linewidth> specification.
Updated answer
Notes:
You can't mix axis choice within a single histogram. So I have removed the axes x1y1 and axes x1y2 from the plot command. Since you have explicitly given the range for both y1 and y2, the plot border and labels are not affected.
However since the green bars are now being plotted against y1, we have to scale them so that the y2 axis labels apply. So the column 3 and column 4 values will be divided by 26, which is (y2 range) / (y1 range)
In "histogram errorbars" mode each plot component looks for an extra column of data to determine the size of the errorbar. Since your column 2 data has no corresponding column of errors, we dummy it up to use all a constant not-a-number (no data) value: (NaN)
Your data contains a line of columnheaders, which could confuse the program if it thinks this is a line of data. There are a number of ways you can tell the program to skip this line; I have used set key autotitle columnhead for convenience and because it is supported by old versions of gnuplot. If you have a current version it would be better to use instead set datafile columnheaders.
I have kept all of your commands except that the plot command is replaced by the following 3 lines:
set style histogram errorbars gap 2 lw 1.5
set key autotitle columnhead
plot 'show-errorbars.dat' using 2:(NaN) ti 'DE' lc 2, '' u ($3/26.):($4/26.):xticlabels(1) ti 'IE' lc 4
I have data I would like to plot in a histogram style with a "cumulated" curve on top. I have the following problem:
My data consists of one column with the categories ("discharge") and one column with the quantity of values ("probability") that belong to the respective category. The last value of the category-column is ">100" summarizing all power plants that have a bigger discharge than the last numeric value ("100 m^3/s"). I have not found a solution to plot this last category and the respective values with the command plot 'datafile.dat' using 1:2 with boxes ... because (as I assume) in this case only numerical values are read out for the x-ticlabels, so the last category is missing. If
I plot it with this command plot 'datafile.dat' using 2:xtics(1) with boxes ... I get the last category ">100" plotted just fine.
BUT: if I use the latter command the x-axis labels appear in the normal font size. Even though I have the line set format x '\footnotesize \%10.0f' in my code.
I have read about explicit labels in the plotcommand line that overwrite format style which was set before but was not able to adapt it to my code.
Changing ytic font size in gnuplot epslatex (multiplot)
Do you have an idea how to do this?

'datafile.dat' using 1:3 with linespoints axes x1y2 ls 1 notitle
I am confused by your datafile; the numbers in the third column do not seem to be cumulative, and do not add up to 100%. Here is a solution that uses only the first two columns of your file:
set term epslatex standalone header "\\usepackage[T1]{fontenc}"
set output 'test.tex'
stats "datafile.dat" using 2
total = STATS_sum
set xlabel "Discharge" offset 0, 1.5
set xtics rotate
set ylabel "No. of power plants"
set ytics nomirror
set yrange [0:*]
set y2label "Cumulative probability"
set y2tics
set y2range [0:]
set boxwidth 0.3 relative
set style line 1 lt 1 lc rgb 'black' lw 2 pt 6 ps 1 dt 2
plot \
'datafile.dat' using 2:xtic("\\footnotesize " . stringcolumn(1)) with boxes axes x1y1 fs pattern 6 lc black notitle, \
'datafile.dat' using ($2/total) smooth cumulative with linespoints axes x1y2 ls 1 notitle
set output
The trick is to add the latex command \footnotesize in front of each label in the using command. It also first computes the total number of power plants so that it can compute probabilities, and computes cumulative values with the smooth cumulative option.
I have the following data:
N Computed Value of pi
y, x
1, 8.0
10, 3.6
100, 3.36
1000, 3.212
10000, 3.152

100000000, 3.14190876
1000000000, 3.141573084
And I am trying format y axis in terms of 10^x
I used the following code:
set terminal pngcairo size 1280,800 enhanced font 'Helvetica,24'
set output "fig.png"
# Title, axis label, range and ticks
set title "Simulations"
set xlabel "Number of Iterations(n)"
set ylabel "Computed values"
# Legend location and grid
set key top left
set grid
set ytics out nomirror
set xtics out nomirror
set format y "10^{%L}"
# Plot the data
plot data.dat" using 2:1 title "" with linesp lw 2 pt 7 ps 1.5
But i am getting the following output:
Please help
Thanks
I had to guess what you really want because there were some inconsistencies. Here is what I believe brings you where you want, changes commented in the source file.
# Title, axis label, range and ticks
set title "Simulations"
set xlabel "Number of Iterations(n)"
set ylabel "Computed values"
# Legend location and grid
set datafile separator comma # gnuplot looks for spaces
# you must tell it about the comma
unset key # same as title "" as you have in your plot command
set grid
set ytics out nomirror
set xtics out nomirror
set logscale x # I guess that's what you want and how it should be
set format x "10^{%L}" # yr x axis is labeled iterations, so I guess
# that's what you want
# Plot the data
plot [][2:10] "data.dat" using 1:2 with linesp lw 2 pt 7 ps 1.5
# swapped 2:1 so that the iterations are on the x axis
# introduced a range for y so that it is better to see
# 'title ""' removed, see 'unset key'
This gives you
May not be exactly what you want but should move you to the next level I hope.
I have files looking like this:
Number Data1 Data2
1 9.10 4.022
2 15.27 3.996
3 21.92 4.004
4 21.19 4.026
5 20.67 4.022
6 20.99 4.000
7 19.80 4.004
8 20.01 3.931
9 20.18 4.004
10 19.78 4.007
I want to plot Number in X axes, Data1 in leftY and Data2 in rightY, but I can not figure out how to do it.
Thanks
Just a brief annotated sample, using your data saved in a file so.dat:
# Set ticks for 2nd y axis
set y2tics
# We don't want to see the left ticks on the right axis
set ytics nomirror
# Set ranges so that the data points are not on the axis
set xrange [0:11]
set yrange [8:23]
set y2range[3.95:4.05]
# use first line of the file for labels
set key autotitle columnhead
# display key in least busy area
set key bottom right
# Title and axis labels
set title "Nice Try"
set xlabel "Number"
set ylabel "Data1"
set y2label "Data2"
plot "so.dat" using 1:2 axes x1y1 with points pointsize 2,\
"" u 1:3 axes x1y2 w p ps 2 pointtype 6
One can do a lot more decoration etc. but I think this is the essence of what you want. The graph produced:
I am executing the following gnuplot script:
set title "Efficiency scatter plot"
set xlabel "perf_1"
set ylabel "secondary report"
set log x
set log y
set xrange [0.1:40.0]
set yrange [0.1:40.0]
set terminal png medium
set output "./graph1.png"
set size square
set multiplot
set pointsize 0.3
set style line 6 pt 6
set datafile separator ","
set border 3
set xtics nomirror
set ytics nomirror
plot '/tmp/data.csv' using 3:1 with points pt 1 lt 3 lc var title "perf_20140113131309", \
'/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.
