How to adjust linewidth in the postscript+eps terminal? I need to get linewidth=1.0 (border or axis), linewidth=1.8 (data-file1), linewidth=1.0 (data-file2)
set terminal postscript eps enhanced font 'Times-Roman,14' lw 1.5
set output 'figure.eps'
...
plot 'P-Density.txt' u 1:(0.415+$2) axes x1y2 title '(1,0,0)' w line lt 1 lc 9 lw 1.8, 'P-Density.txt' u 1:(0.472+$3) axes x1y2 title '(1,1,0)' w line lt 1 lc 1 lw 1.8, 'P-Density.txt' u 1:(0.658+$4) axes x1y2 title '(1,2,0)' w line lt 1 lc 3 lw 1.8, 'Potential.txt' u 1:2 title '' w line ls -1 lw 1.2, 'enerji2_7_1.txt' u 1:2 title '' w line lt 2 lc 9 lw 1.0, 'enerji2_7_2.txt' u 1:2 title '' w line lt 2 lc 1 lw 1.0, 'enerji2_7_3.txt' u 1:2 title '' w line lt 2 lc 3 lw 1.0
In the "postscript" terminal, the thickness of the tick marks will follow the line width set by the set border command, but the border is designed to be twice as thick.
Then, if you want the border line to be 1.0 thickness, you can set it as follows.
set border lw 0.5
Instead, the tick marks thickness will be set to 0.5.
If you want the line width of the border and tick marks to match, you need to change the contents of the file "prologue.ps", which is embedded in the header of the output postscript file. gnuplot provides a mechanism to replace this header with your own customized "prologue.ps" file. See help set psdir for details.
You can try it by copying the 'prologue.ps' file that comes with gnuplot to the current directory, and changing the line,
/LTB {BL [] LCb DL} def
to the following.
/LTB {PL [] LCb DL} def
Then, change your script as,
set terminal postscript eps enhanced font 'Times-Roman,14'
set psdir '.'
set output 'figure.eps'
set border lw 1.0
... your plot command ...

I want to set the background of data labels to white! The considered plot is a data plot of the following data (gnuDC.dat):
4 1570.96 1571
8 770.63 771
12 530.33 530
16 385.13 385
24 261.87 262
48 137.71 138
96 81.42 81
The plot command reads:
plot "gnuDC.dat" using 1:2 title "DC: GNU Fortran 4.7.2 + Open MPI 1.6.3" w p ls 1, \
"gnuDC.dat" using 1:2:3 with labels center offset 2.,0.7 font "Helvetica,14" tc ls 4 notitle, \
"gnuDC.dat" using 1:3 notitle smooth csplines ls 14
Which gives me:
It looks ok but think one could read the lables better when the would have an white background. Is there an easy way to add the white background for all labels at once?
Here is the whole print file:

With gnuplot version 5 there is a boxed option which does exactly this: give labels a background and, if you want, also a border. The style is controlled with set style textbox, e.g.
set style textbox opaque noborder
plot ... with labels boxed ...
Applied to your script (with some minor changes due to the changed dash handling since 5.0):
# Line style for axes
set style line 80 lt rgb "#808080"
# Line style for grid
set style line 81 dt 3 # dashed
set style line 81 lt rgb "#808080" lw 0.5 # grey

No, for versions 4.6 and earlier there isn't an easy way to achieve this.
I want to trace some curves with gnuplot. I recently change my computer and now I have a MacOSX 10.9.5
In my other computer, colors appeared in my .eps figure, but with my Mac not anymore, and an error message appears : "· Times not found, using Courier." which is an other problem I think.
My gnuplot version is Version 5.0 patchlevel 0.
Here is my trace.p that I load with gnuplot with
$ gnuplot
gnuplot > load "trace.p"
set autoscale
unset logscale
unset label
set term postscript enhanced 'Times'
set output"E_Hxc_bath_exact_weak.eps"

plot (0.25 - (3/4)/(sqrt(1+64/(x**2)) + 2*sqrt(1+16/(x**2)))) with lines ls 7 title "exact", (0.25 - 3*(x**2)/64 + (x**3)/(2*16*16)) with lines ls 1 title "weak";
Some lines are certainly useless, but I don't know why the result is colorless, maybe I miss an application or something...
Try adding the color flag to the set term line in your script.
For the dashed lines which didn't appear, it is because in version 5.0, the command change, it is no more linetype but dashtype.
See the response of Gnuplot line types for more precision.
I would like to plot a legend/key, which shows the different symbols on the line. Currently my plots look like this:
Unfortunately the symbols (triangle, rectangle and circle) are not shown in the key/legend. How is it possible to add them?
I use the following gnuplot script:
set title tit font "palatino,20"
set xlabel xlbl font "palatino,20"
set ylabel ylbl font "palatino,20"
#set logscale x
set output graphfilename.".pdf"
set terminal pdf

set style line 2 lc rgb '#00ad60' lt 1 lw 2 pt 7 # red .
set style line 3 lc rgb '#ad0000' lt 1 lw 2 pt 9 # green .
set tics scale 0.8

plot file1 using ($1/1000):($2/1000000):($3/1000000):($4/1000000) notitle w yerrorbars ls 1, \

'' using ($1/1000):($2/1000000) title "Java" w lines ls 3
Generally, you can get both lines and points, if you plot with the linespoints plotting style:
sc(x) = x*1e-6
plot file1 using ($1/1000):(sc($2)):(sc($3)):(sc($4)) notitle w yerrorbars ls 1 ps 0.5, \
'' using ($1/1000):(sc($2)) title "Hlog" w linespoints ls 1
That draws the points twice, which shouldn't be a problem unless you use transparency. I also shrinked the points which are drawn together with the errorbars to 50%, so you don't get problems with antialiasing.
As another option you could add the title only the the errorbars, in which case the legend would look like |---x---| (i.e. contain also the errorbars):
sc(x) = x*1e-6
plot file1 using ($1/1000):(sc($2)):(sc($3)):(sc($4)) title "Hlog" w yerrorbars ls 1, \
'' using ($1/1000):(sc($2)) notitle w lines ls 1
I'm trying to plot a figure that contains both dashed and continuous lines with gnuplot v4.4 . The code is:
set term postscript eps enhanced color
set style line 1 linetype 1 lw 2
set style line 2 linetype 1 lw 2 linecolor rgb 'green'
set style line 3 linetype 1 lw 2 linecolor rgb 'blue'
set style line 4 linetype 4 lw 2 linecolor rgb 'red'
set style line 5 linetype 3 lw 2 linecolor rgb 'blue'
set border lw 3
set xtics font ',18'
set ytics font ',18'
set output 'roc.ps'
set key right bottom
plot 'roc_fpdock_isc_test' u 1:2 w l ls 1 title "Full optimization, test set" ,x w l ls 2 title "Random", 'roc_fpdock_isc_training' u 1:2 w l ls 3 title "Full optimization, training set", 'roc_mini_pep_sc_training' u 1:2 w l ls 4 title "Minimization only, training set", 'roc_mini_pep_sc_test' u 1:2 w l ls 5 title "Minimization only, test set"
Problem is , I can't plot it to png. When I change the set term instruction to: set term png enhanced I get only continuous lines.
Any idea what went wrong?
It turns out that I can't seem to get dashed lines in the png terminal either (the one with the GD backend). However, if you have the cairo terminals, you can get a png with dashed lines (assuming you pick the appropriate linetypes).
set term pngcairo dashed
set output "foo.png"
test
!display foo.png
!rm foo.png
As an aside, test is fantastic for inquiring what the behavior of a particular terminal will be.
You have the dt option for dashtype in pngcairo. Legend here:
e.g
set style line 5 linetype 3 dt 5 lw 3 linecolor rgb 'green'
gives dashtype 5
I'm plotting some data curves with gnuplot, and they look like this:
However, the line samples in the legend are too thin. When you have more curves, it becomes hard to distinguish the colors. You can increase the thickness of the curves using "linewidth", e.g., by adding "lw 3" to the plot command, and you'd get this:
However, this increases the thickness everywhere. Is it possible to make the lines thick in the legend only? I know it can be done "the other way", by postprocessing on the output .png file. But is there a direct approach, using some gnuplot setting/wizardry?
Unfortunately, I don't know a way to control the thickness of the lines in the key, since they correspond to the lines being drawn. You can see what you can change by typing help set key in gnuplot.
Using multiplot, you can draw the plot lines first without the key, then draw the key again for 'ghost lines'. Here is a code sample which would do that:
set terminal png color size 800,600
set output 'plot.png'
set multiplot
unset key
plot '../batteries/9v/carrefour.txt' w lp, \
'../batteries/9v/philips.txt' w lp, \
'../batteries/9v/sony.txt' w lp
set key; unset tics; unset border; unset xlabel; unset ylabel
plot [][0:1] 2 title 'Carrefour' lw 4, \
2 title 'Philips' lw 4, \
2 title 'Sony' lw 4
In the second plot command, the function 2 (a constant) is being plotted with a y range of 0 to 1, so it doesn't show up.
I ran across this post and it gave me a critical idea.
The provided solution does not work in multiplot mode, since the second plot command will trigger the second plot, which is most likely not desired.
as a workaround one can set the original data as "notitle", then plot data outside of range with the same linetype and color in different thickness with the desired title. I'll just leave my current example here. It also includes linestyles that i have declared. So i just use the same linestyle (ls) to get the same color but change the thickness on the second line.

An even more simple work-around (imho) is to define the colours explicitly and plot each line twice, once with high lw for the key and also with the title to appear in the key, but adding "every ::0::0" which effectively ends up in plotting nothing, and once the normal way. See the following code snippet:
plot data u 0:1 w l linecolor rgb #1b9e77 lw 2 t "",\
data every ::0::0 u 0:1 w l linecolor rgb #1b9e77 lw 4 t "Title"
To expand on the NaN comment by #Svalorzen, the following will graph two lines of width 1 from some datafile.txt with no titles and create matching blank lines with the specified titles and width 5 for the key only:
plot [][]\
NaN title "Title1" w line lt 1 lc 1 lw 5,\
NaN title "Title2" w line lt 1 lc 2 lw 5,\
"datafile.txt" using 1:2 title "" w line lt 1 lc 1 lw 1,\
"datafile.txt" using 1:3 title "" w line lt 1 lc 2 lw 1
I find an answer for this:
Set key linewidth
in your case, must be:
plot '../batteries/9v/carrefour.txt' w l lw 1 linetype 1 notitle, 0/0 linetype 1 linewidth 5 title 'Carrefour'
rep '../batteries/9v/philips.txt' w l lw 1 linetype 2 notitle, 0/0 linetype 2 linewidth 5 title 'Philips'
rep '../batteries/9v/sony.txt' w l lw 1, linetype 3 notitle, 0/0 linetype 3 linewidth 5 title 'Sony'
Try something like:
plot # ... \
keyentry w l lw 1 lc 2 t "Title" # ...
And remove the old keys.
