I need to create a number of vertical gradients in my plot - four in total, in order to clarify direction (N,E,S,W).
#set 0 to 45 degrees color
set obj 1 rectangle behind from screen 0.09,0.2 to screen 0.89,0.29
set palette model RGB defined ( 0 "white", 1 "red")
set cbrange[0:1]
unset colorbox
Am I missing something here?
Thanks in advance
You cannot fill a rectangle with a gradient. The palette affects only plotted functions or data sets. You can either use the image or pm3d plotting style to do this.
One example:
set samples 100
set isosample 100,100
set xrange [0:1]
set yrange [0:1]
set palette defined (0 "white", 1 "red")
set autoscale cbfix
unset colorbox
unset key
set multiplot layout 2,2
plot '++' using 1:2:1 with image
plot '++' using 1:2:2 with image
plot '++' using 1:2:(-$1) with image
plot '++' using 1:2:(-$2) with image
unset multiplot
The output with the pngcairo terminal and version 4.6.5 is:
Now you must find a way to integrate this with the other plots you have.

I am trying to plot an inlet graph which is shown in Figure. Being an inlet graph it is needed to show x tics and y ticks of relatively big sizes for clear visibility. But when I increase the fonts as,
set xtics font ", 40"
tics overlaps with axis. I increased the plot size set term png size 1000, 1000 but still the issue persists. Kindly suggest if there is a way to move the tics below or to a desired position in graph.
Edit:
The gnuplot script looks like this,
set term png size 1000, 1000
set output "b_vs_N.png"
set style fill solid
set style circle radius 0.001
FIT_LIMIT=1.e-14
set yrange [0.15:0.25]
set style fill solid
set style circle radius 0.001
set xtics 10
set ytics 0.03
set border 15 back lw 6
set xtics font ", 40"
set ytics font ", 22"
set ylabel "b" enhanced font "1 {,40}"
set xlabel "N_i" font "1 {,40}"
set lmargin 12
set bmargin 4
set palette model HSV
set palette rgb 3,2,2
set palette maxcolors 12
set view map
AA(x)=a+b*x+c*x**2
fit AA(x) "data.txt" using 1:2 via c, b, a
plot "data.txt" using 1:2 lt 1 pt 11 ps 2.0 lc rgb "black" notitle, AA(x) w lines lw 2 lc rgb "sienna1" notitle
Your example is uncomplete without code and therefore difficult to reproduce. Please check help xtics. There is the option offset.
Maybe the following example helps to solve your issue.
In the example below no special offset seems to be necessary, i.e. offset 0,0, but you can shift and adjust the labels in x and y direction.
Code:
### tic label offset
reset session
set multiplot
plot sin(x)/x
set origin 0.07, 0.6
set size 0.3,0.3
set xrange [0:10]
set xtics 5 out font ",20" offset 0,0
plot x**2
unset multiplot
### end of code

I posted a question previously about plotting multiple 3D surfaces together as a multiplot. I got the solution for that but now I am having issue with controlling the fonts of the graphs.
The fonts are terrible in multiplot and My settings are not doing anything with them
I don't know how to control these fonts. I tried ztics but it does not change anything
Here is my code:
set terminal png size 2000,1600 enhanced transparent
set encoding utf8 #iso_8859_1
set output 'output.png'
set border linewidth 2
set pm3d border lw 2
####Set the Axis and Axis-Labels Formatting####
set format '%g'
set xtics font "Helvetica,26" scale 3 # Font for xtics
set xtics offset 3,-1.5 # Put xtics away from the axis
set ytics font "Helvetica,26" scale 3
set ytics offset 3,0 # Put ytics away from the axis
set ztics font "Helvetica,26" scale 3
set ztics 5 # Difference between numbers on Y-axis
set format z "" # To hide ztics on the left side
set grid # Show gridlines on both axis
set pm3d interpolate 1,1
unset key

Please suggest how can I control the settings for fonts in multiplot and how can I control the fonts of the "key" appearing on the right side (circled red in figure).
I am unable to insert the links of the input files due to less reputation :(
Thanks for your help.
I'm trying to add some guiding lines over a pm3d map using Gnuplot.
Below is the code I use to plot pm3d map (my pm3d map).
set terminal post eps enhanced color solid "Helvetica" 16
set encoding iso_8859_1
set hidden3d
set pm3d map
set view map
unset surface
set size square
splot "map.ene" with image
set xlabel "RC1 ({\305})"
set ylabel "RC2 ({\305})"
set cblabel "{/Symbol D}G (kcal/mol)" offset 1,0,0
set xrange ["1":"11"]
set yrange ["5.5":"9.5"]
set cbrange ["-3.1":"0.0"]
set xtics 1
set ytics 1
set cbtics 1
set mxtics 2
set mytics 5
unset key
set palette defined (-3.1 "red", -2.5 "yellow", -1.5 "green", -0.5 "blue", 0 "white")
unset colorbox
set output "map.eps"
replot
map.ene is in the format below:
1.000 5.500 0.00000 i
Now I want to add a vertical line (x=5.5) over the pm3d figure. I searched old posts and found similar questions already been asked by others. Seems there are two possible solutions:
1) prepare a separate data file for the line (x.dat, 5.5,y,0.0) then use command below to plot.
splot "map.ene" with pm3d, "x.dat" using 1:2:(0.0) with points linecolor rgb "black"
2) use "multiplot" facility in Gnuplot.
I tried both, neither worked. I've been playing this for a while but sill not sure how I should modify my original pm3d code to add guiding lines.
you can draw lines in gnuplot:
set arrow from first 5.5, graph 0 to first 5.5, graph 1 nohead
type help coordinates to better tune the above command.
I am using multiplot to plot four graphs. My code is given below
set term postscript eps enhanced color
set pm3d map
set pm3d corners2color c1
set size square
set out 'defect2.eps'
unset colorbox
set colorbox horiz user origin 0.1,0.7 size 0.8,0.02
set cbrange [-1.6:0]
set xtics 25
set ytics 25
set lmargin at screen 0.1
set rmargin at screen 0.9
set multiplot layout 1,4
set xlabel "i" font "Times-italic,20"
set ylabel "j" font "Times-italic,20"
spl 'defect.dat' notitle
unset ylabel
spl 'defect_2.dat' notitle
spl 'defect_3.dat' notitle
spl 'defect_4.dat' notitle
unset multiplot
set out
This produces a following plot
However, individual plots in the picture are not properly placed. I cannot see ylabel for the first plot as it is hidden behind the screen whereas there are large blank gaps between those plots. Is there any way to reduce these gaps, increase size of these plots and show the labels properly?
Thanks in advance.
The Problem is your margin setting. The margin defines the size of the white stripe between the box containing the plot and the border of the window.
This means, tic and axis labels are printet on the Martin area! And your 10% of window width is not enough, so the labels are clipped.
So you can adjust the margins to shift all plots more to the left or adjust label font sites and offsets (Miguel's comment).
I use gnu plot to draw a multiplot and in my script I set the y label like that:
set ylabel "foobar"
Now every plot in the multiplot has a dedicated y label on their y axis. However, I would like to have only one y label for all the plots in the multiplot and center that label also on the common y axis. How can I do that? The multiplot layout I use is a 7.1 So all the plots have the same y axis.
The simplest way is to make the first plot, then turn off the y label:
set ylabel 'foo'
set multiplot
plot 'data1.dat'
unset ylabel
plot 'data2.dat'
plot ...
unset multiplot
This will make the x-dimension of the first plot different from that of all the other plots, so you may have to play with the margins if you want all the plots the exact same size.
Plot the individual panels of reduced size without labels but with border, tics and title, then define a full-sized panel with labels but without border, tics and title.You may have to plot a dummy function (1/0).
Global label workaround
This is not ideal, but if you desperate like me, you can use a rotated global label + larger left margins:
#!/usr/bin/env gnuplot
label_label_size = 14
set terminal png
set output "gnuplot.png"
set multiplot layout 2,1 title "Multiplot with one ylabel" font ",18"
set lmargin 10
set label "My y-label" at screen 0.05,0.5 center front rotate \
font "," . label_label_size
plot sin(x)
set xlabel 'My x-label' font "," . label_label_size
plot cos(x)
Here is a realistic application that motivated me to do this: Heap vs Binary Search Tree (BST)
Tested in gnuplot 5.2 patchlevel 6, Ubuntu 19.04.
This is basically the suggestion from Fabian Claremont's answer, but (for beginners) put into code and visualized. Actually, Ciro Santilli's solution is even shorter.
Tested with gnuplot 5.2. For gnuplot 4.6 (the time of OP's question), replace reset session with reset and set margin 8,-1,1-1 with set lmargin 8 and set bmargin 1.
Code:
### Multiplot with single y-label
reset session
unset key
set sample 500
set multiplot layout 7,1
unset ylabel
set linetype 1 lc rgb "red"
set margins 8,-1,1,-1 # left, right, bottom, top (-1=auto)
set ytic 1.0
set title "Plot 1" offset 0,-1
plot sin(1*x)
set title "Plot 2" offset 0,-1
plot sin(2*x)
set title "Plot 3" offset 0,-1
plot sin(3*x)
set title "Plot 4" offset 0,-1
plot sin(4*x)
set title "Plot 5" offset 0,-1
plot sin(5*x)
set title "Plot 6" offset 0,-1
plot sin(6*x)
set title "Plot 7" offset 0,-1
plot sin(7*x)
set lmargin -1 # automatic lmargin
unset title
set origin 0,0
set size 1,1
set border 0
unset tics
set ylabel "This is a centered y-label"
plot [][0:1] -1 # plot a dummy line out of range
unset multiplot
