What is wrong with this?
set ylabel 1.0,0.0
set ylabel "{/:Italic M}" font "Allert,12"
The error is
unexpected or unrecognized token
Thank you
It would help to make your question a little more explicit about what you intend to do.
Guessing from your code, possibly you want to have italic M label with an offset of (1,0). This would write
set ylabel "{/:Italic M}" font "Allert,12" offset 1,0
Indeed the first number in offset will set the distance between y-axis and label. What you were missing is simply this offset keyword in the first line :
set ylabel offset 1.0,0.0
If you do
gnuplot>?set xlabel
Syntax:
set xlabel {"<label>"} {offset <offset>} {font "<font>{,<size>}"}
{textcolor <colorspec>} {{no}enhanced}
{rotate by <degrees> | rotate parallel | norotate}
show xlabel
It seems you cannot give x,y positions to the labels. What you can do is give it dx,dy offsets:
> set ylabel "{/:Italic M}" font "Allert,12" offset dx,dy
Hope this helps.

I have problems changing the font size of my ytics (xtics as well) in an epslatex gnuplot.
I tried set format y '\tiny{%g}'
It is only working for the first of the two plots.
This is my code:
set terminal epslatex
set output "w_alt_nsyB_multi.tex"
set multiplot layout 1,1
set xrange [-0.5:17]
set yrange [0:110]
set xlabel "days"
set ylabel "Survival (\\%)" offset 2.5
set key reverse
set xtics font 'Arial,4' s
et style histogram errorbars gap 2 lw 1
set style data histogram
set style fill solid 1 border lt -1
set boxwidth 0.8
plot 'w_alt_nsyB.dat' every ::::7 using 2:3:xticlabels(1) title 'w1118' lt rgb "#000000",\
'w_alt_nsyB.dat' every ::::7 using 4:5 title 'wtSYN' lt rgb "#FF0000",\
'w_alt_elav_endoG.dat' every ::::7 using 6:7 title '38085' lt rgb "#9400D3"
set origin 0.5, 0.25
set size 0.5, 0.5
set xrange [-0.5:6]
set yrange [0:110]
set xlabel "\\tiny{Time of $Mn^{2+}$ treatment}"
set ytics ('10'10,'50'50,'100'100) nomirror
unset border
set xtics nomirror
unset ylabel
unset key
plot 'w_alt_nsyB_100.dat' using 2:3:xticlabels(1) lt rgb "#000000",\
'w_alt_nsyB_100.dat' using 4:5:xticlabels(1) lt rgb "#FF0000",\
'w_alt_nsyB_100.dat' using 6:7:xticlabels(1) lt rgb "#9400D3"
unset multiplot
Can anyone help me please?
The format given in set format ... isn't applied if you give an explicit manual label like you do with
set ytics ('10'10,'50'50,'100'100)
You must either just give the locations of the labels
set format y '\tiny %g'
set ytics (10, 50, 100)
or include the font macro in every manual label
set ytics ('\tiny 10' 10, '\tiny 50' 50, '\tiny 100' 100)
Note also, that your syntax \tiny{%g} is wrong, \tiny is only a switch and doesn't take any arguments. In this case it doesn't matter, because every label is wrapped in an individual LaTeX box, but in other situations it makes a big difference. To wrap the tiny font you would usually need {\tiny %g}.
The same happens for the explicit labels which are set with xticlabel. Also here, the format from set format x doesn't apply. Instead of giving a column number to xticlabel (like xticlabel(1) in your example), you must give the complete label string including the macro:
xl(c) = sprintf('\tiny %s', strcol(c))
plot 'file.dat' using 2:3:xticlabel(xl(1))
Next time, please give a minimal example which allows others to reproduce your problem. We don't have your data files to run the script. And your problem isn't related to you specific data file, so you can as well construct an example using functions, which possibly leads you itself to the solution...
Based on this post (I am using gnuplot gnuplot 4.6 patchlevel 1):
gnuplot: max and min values in a range
I am trying to use set yr [GPVAL_DATA_Y_MIN:GPVAL_DATA_Y_MAX] in my .pg script that plots data from this .dat file:
100 2
200 4
300 9
But I get:
undefined variable: GPVAL_DATA_Y_MIN
This is my script:
set terminal png
set output 'img.png'
set xlabel 'x-label'
set ylabel 'y-label'
set boxwidth 0.5
set style fill solid
set yrange [GPVAL_DATA_Y_MIN:GPVAL_DATA_Y_MAX]
plot 'sample.dat' with boxes title ""
Any ideas?
The gnuplot-defined variables are available only after a plot command (In the question you linked to, a replot is used to plot again).
Basically you have different options:
First plot to terminal unknown, and then change to the real terminal, set the range (now the variables are available), and replot:
set xlabel 'x-label'
set ylabel 'y-label'
set boxwidth 0.5 relative
set style fill solid
set terminal unknown
plot 'sample.dat' with boxes title ""
set terminal pngcairo
set output 'img.png'
set yrange [GPVAL_DATA_Y_MIN:GPVAL_DATA_Y_MAX]
replot
Note, that I used the pngcairo terminal, which gives much better results, than the png terminal. And I used set boxwidth 0.5 relative.
Use set autoscale to fix the ranges instead of setting an explicit yrange. You can use set offset to specify a margin based on the autoscaled values:
set autoscale yfix
# set offset 0,0,0.5,0.5
plot 'sample.dat' with boxes title ''
Use the stats command to extract the minimum and maximum values:
stats 'sample.dat' using 1:2
set yrange[STATS_min_y:STATS_max_y]
plot 'sample.dat' with boxes title ''
I am trying to use gnuplot to plot the graphene band structure as both surfaces and a countour plot at the base, set with set contour base, but I can't get rid of some axis lines and the plane where the contour is drawn is too far away from the surfaces when I place them in the adequate viewing angle.
Here is the code to plot the graph
# Setting ranges and function parameters
set xrange [-.55:.55]
set yrange [-1:1]
t=-3.033 s=0.129 a=1.43 * sqrt(3)
# Auxiliary functions
kx(x,y) = (2*pi/a) * (cos(pi/6)*x + sin(pi/6)*y) ky(x,y) = (2*pi/a) * (cos(pi/6)*x - sin(pi/6)*y)
w(x,y) = sqrt(1+4*cos(0.5*sqrt(3)*kx(x,y)*a)*cos(0.5*a*ky(x,y)) + 4*(cos(0.5*ky(x,y)*a))**2)
#functions to be plotted
e(x,y) = (t*w(x,y))/(1+s*w(x,y))
e_estrela(x,y) = (-t*w(x,y))/(1-s*w(x,y))
# Setting up 3D plot appearance
set hidden3d
set contour base set cntrparam levels discrete 0,0.5,1,2,4,8
set view 75, 31, 0.601098, 1.4385
set isosamples 60
# Removing unwanted stuff
unset xtics
unset ytics
unset ztics
unset key
splot e_estrela(x,y), e(x,y)
And the output I get (with the pngcairo terminal, but that's not relevant, I guess) is:
Is it possible to draw the contour base plane closer to the surfaces? And how about removing those vertical black lines?
For the first part, I tried playing wioth set zrange with no success. The base plane seems to be drawn a certain z-distance below the lowest z-range limit everytime.
Ideas? Thanks in advance!
To adjust the distance between your data and the xy-plane use the option
set xyplane relative <value>
where <value> gives you the distance between the xy-plane and the minimal z-value in relative fraction of the hight of your plot. So <value>=0 sets the distance to zero, <value>=0.5 to half the hight.
To control the border use set border where each border line is represented by bits. Please refers to the documentation for more details. In your case I would suggest:
set border 127+256+512 # or set border 1023-128
set grid #forces borders from xy-plane to plot
I'm trying to put two figures side by side using gnuplot with multiplot.
I want the resulting image to be rectangular so I use set size 2, 1. I also set the set multiplot layout 1, 2 option. However, the resulting image only uses the left part of the available space. Any help will be appreciated.
Thanks
Ahmet
Here is the resulting image
http://tinypic.com/r/33mlz04/6
And below is the gnuplot commands I'm using.
set terminal postscript eps color enhanced
set output 'figure.eps';
set size 2,1;
set multiplot layout 1, 2 ;
set title "Figure 1";
plot "data1.txt"
set title "Figure 1";
plot "data2.txt"
unset multiplot
Although I'm not very sure, with some trial and error I have solved it
set terminal postscript eps color enhanced
set output 'eps/image.eps';
set size 1,0.5;
set multiplot layout 1, 2 ;
set title "Figure 1";
set size 0.5,0.5;
plot "data/data1.txt"
set title "Figure 1";
set size 0.5,0.5;
plot "data/data2.txt"
unset multiplot
Try something like:
set terminal postscript eps color enhanced size 10,5
set output 'figure.eps';
set multiplot layout 1, 2 ;
set title "Figure 1";
plot "data1.txt"
set title "Figure 1";
plot "data2.txt"
unset multiplot
When you set the size on the terminal specification line, that determines the actual size of the plot canvas (in inches in this case). When you use set size on a separate line, that sets the size of the plot in relative units of the canvas size. This is different in older versions of gnuplot. For perhaps a better explanation, try help set size in gnuplot.
For even more control over the size/position of the plot, you can use set origin in conjuction with set size to change the placement and size of each plot. Finally, the most control can be achieved with set lmargin at <place> (and set rmargin ...) and so-on for tmargin and bmargin where the "lrtb" stand for left, right, top and bottom respectively.
So, to get a plot to fill all of the available space (left to right), you could:
set multiplot
set lmargin at 0
set rmargin at .5
plot sin(x)
set lmargin at .5
set rmargin at 1
plot cos(x)
unset multiplot
However, this is (usually) overkill. Usually gnuplot tries to make the margins big enough for your labels and such, but setting the margin explicitly disables that. I would suggest you go with the solution by andyras.
if you are having problems using this method for more than 2 figures add 'set origin 0,0' after 'set size 0.5,0.5'.
For example, for three figures :
set terminal postscript eps color enhanced
set output 'eps/image.eps';
set size 1.5,0.5;
set multiplot layout 1, 3 ;
set title "Figure 1";
set size 0.5,0.5;
set origin 0,0
plot "data/data1.txt"
set title "Figure 2";
set size 0.5,0.5;
set origin 0,0
plot "data/data3.txt"
set title "Figure 3";
set size 0.5,0.5;
set origin 0,0
plot "data/data3.txt"
unset multiplot
I want the below desired effect
I am using a gnuplot script similar to this
reset
set term postscript eps enhanced "Helvetica" 30
set size square
set xlabel "X position"
set ylabel "Y position"
set pm3d map
set palette rgbformulae 22,13,-31
set xrange [0 : 22.0000000000]
set yrange [0 : 17.0000000000]
set zrange [0 : 0.1614027105]
set xtics 5
set ytics 0,4
set cbtics 0,0.020
set style line 1 lw 1
unset key
set dgrid3d 45,45
set style line 1 lt 1
set hidden3d
splot "data.data" u 1:2:3
set label "98.8" at 9,-2 textcolor lt 1
set label "1.2" at 9,6 textcolor lt 1
But when I do, the labels (98.8, and 1.2) don't get printed. If I provide a bogus data.data file, lets say with only a single (x,y,z) point, then nothing gets graphed and I can see the labels. Therefore, I am guessing that my graph is occluding my labels. How do I get the labels to be printed on top of my graph?
The default placement for labels is in back.
But you can specify that the label show up in front, e.g.:
set label "label in front" at 2.5,0.5 tc rgb "white" font ",30" front
Credit: the (very slightly modified) code for this was found at http://gnuplot.sourceforge.net/demo_svg_4.5/pm3dcolors.html and/or link(s) therefrom.
Also for further information on the placement of text in gnuplot, I found this reference to be very useful.
