I want to plot a surface where each face has a different pm3d style. I tried the following:
reset
set format x "%.6f"
set format y "%.6f"
set format z "%.6f"
set xrange[-10:10]
set xtics border -10,5,10
set yrange[-10:10]
set ytics border -10,5,10
set cbrange[0:2]
set pm3d depthorder
set palette defined (0 'green', 1 'red', 1 'blue', 2 'black')
splot "pm3d1_1.dat" using 1:2:3:($3/200) with pm3d, "pm3d1_1.dat" using 1:2:($3-1):($3/200+1) with pm3d
where 'pm3d1_1.dat' is the function z=xx+yy with z varying between 0 and 200 (x,y between -10 and 10). The problem is that the output doesn't look how I expected when viewed from certain points of view, like this one:
I'd appreciate any help and I'd like to know if there is an alternative to plot a surface with different pm3d styles on each face. Thanks.
I guess it has to with the way depthorder sorts the quadrangles. Don't know if this could be fixed. To extend your question, here is an example without external data file, which also shows the problem:
set xrange[-10:10]
set yrange[-10:10]
set zrange[-1:200]
set isosamples 20
set pm3d depthorder
set ticslevel 0
set view 65,28
set palette defined (0 'green', 1 'red', 1 'blue', 2 'black')
splot '++' using 1:2:(z=$1**2+$2**2):(z/200.0) w pm3d,\
'++' using 1:2:(z=$1**2+$2**2, z-1):(z/200.0+1) w pm3d
Result (with 4.6.4):
Don't know of any other way to plot this. Maybe I'll submit the above script as bug report.

my gnuplot script plot bar graphs in the following 2D format:
using the following sctipt:
set term pngcairo size 800,600
set termoption noenhanced
set title "$file_name" font "Century,22" textcolor "#b8860b"
set tics font "Helvetica,10"
#set xtics noenhanced
set ylabel "Fraction, %"
set xlabel "H-bond donor/aceptor, residue"
set yrange [0:1]

set style fill solid 0.5
plot '<cat' using 2:xtic(1) with boxes
In order to add values above the bars, I've tried to modify it to
plot '<cat' using 0:2:xtic(1) with boxes, '' u 0:2:2 w labels offset 0,1
but the values were not added to the bars, with the following warning
"/dev/fd/63" line 17: warning: Skipping data file with no valid points
I can only test for Windows, but I assume cat under Linux is the equivalent for type under Windows.
So, what is your filename? I would say your filename is simply missing. Check help piped-data.
Something like the following should work:
plot '<cat myDataFile.dat' using 0:2:xtic(1) with boxes, '' u 0:2:2 w labels offset 0,1
But then, what is the difference to using directly the filename?
plot 'myDataFile.dat' using 0:2:xtic(1) with boxes, '' u 0:2:2 w labels offset 0,1
I'm trying to generate a heat map from data (https://pastebin.com/AgivvGgX). The data are not in the "matrix" form.
I tried to use pm3d map and I obtained the following plot:
I also tried to use dgrid3d and view map:
set view map
set pal def
set dgrid3d 40,40,3
splot "plot.dat" using 1:2:3 u pm3d
And I obtained the following result:
Both the plots are not correct. The dgird3d keyword creates artifacts where there are not data points.
I obtained a nice plot using the code:
set view map
set pal def
splot "plot.dat" using 1:2:3 with points pointtype 5 pointsize 1 palette linewidth 8
Here the result
I would like to obtain a map similar to the latter one, but not with discrete points or squares but as a continuous heat map and have a white background where data are not present. Is it possible?
Since your data is irregular, you should use dgrid3d. It has various options (see help dgrid3d), here is a picture I've got while trying different kernels and options:
set view map
set palette defined (0 'white', 1 'blue', 2 'green', 3 'yellow', 4 'red')
set dgrid3d 100,100 exp kdensity 10,10
splot 'plot.dat' w pm3d palette
set dgrid3d 100,100 gauss kdensity 30,30
replot
I am trying to create a graphic using gnuplot 5.0 with two scales in the same x axis. I have managed to create one using the multiplot option with the following code:
reset
set terminal pngcairo
set output "test.png"
unset key
set ylabel "Temperature (C)"
set ytics nomirror
set yrange[0:7]
set multiplot layout 1,2
set xrange [0:5.99] #Avoid plotting the last xtics in the first graphic
set xlabel "Heating time (minutes)"
set rmargin at screen 0.7
plot x
set xrange [0:4]
set xlabel "Seconds after stop"
set rmargin
set lmargin at screen 0.7
set xtics 1
unset ylabel
unset ytics
set y2tics nomirror
set format y2 ''
f(x) = a * exp (-x*b)
a=6
b=1
plot f(x)
With this result:
I want to generate several images like this one and add them in a multiplot arrangement, but I am not sure if using nested multiplots will be easy. Is there an easier way to obtain each of the images without using multiplot, like splitting the xaxis in two components?
Thanks in advance.
Just in case this still might be of interest to the OP or somebody else... You don't explicitly write whether you want to plot functions or data from a datafile. In your examples you use functions.
You can do something without "nested" multiplots, which would certainly be possible as well, but probably getting a bit confusing.
So, maybe the following might be easier. You basically set the xtics "manually". In order to avoid typing the same code several times you can use macros (check help macros).
Code:
### multiplot graph with different x-axis scales
reset session
# define functions
Temperature(x) = x<t0 ? x*a/t0 : a*exp(-(x-t0)*b)
myColor(col) = column(col)<t0 ? 0xff0000 : 0x0000ff
myTic(x,t) = sprintf("%g", x<=t ? x : x-t)
# define macro
myPlot = "\
set xrange[0:t0+t1]; \
set arrow 1 from first t0, graph 0 to first t0, graph 1 nohead; \
set label 1 'heating' center at first t0/2., graph 0 offset 0,-2; \
set label 2 'cooling' center at first (t0+t1/2.), graph 0 offset 0,-2; \
set xtics (); \
do for [i=0:int(t0/dt1)] { set xtics add (myTic(i*dt1,t0) i*dt1) }; \
do for [i=0:int(t1/dt2)] { set xtics add (myTic(i*dt2,t1) i*dt2+t0) }; \
plot '+' u 1:(Temperature($1)):(myColor(1)) w l lc rgb var "
set samples 200
set key noautotitle
set bmargin 3
set ylabel "Temperature"
set grid x,y
set multiplot layout 2,2
t0=6; t1=4; dt1=1; dt2=1; a=6; b=1
#myPlot
t0=4; t1=10; dt1=1; dt2=2; a=4; b=0.5
#myPlot
t0=20; t1=30; dt1=5; dt2=10; a=2; b=0.1
#myPlot

Result:
When plotting an X,Y,Z data set as color map I need to smoothen the plot a bit. The data are sparse and I need some sort of gaussian blur applied to the result.
Using following code :
reset
#set zrange [2:6]
set contour
unset surface
set cntrparam levels incr 2.0,0.5,8.0
set view map
set xrange [0:2184]
set yrange [0:1472]
set dgrid3d 100,100,4
set table "ap130_base_contour.txt"
splot 'ap130_base.dat' using 11:12:14
unset table
unset contour
set surface
set table "ap130_base_dgrid.txt"
splot 'ap130_base.dat' using 11:12:14
unset table
reset
set pm3d map
unset key
set palette defined (0 '#352a87', 1 '#0363e1',2 '#1485d4', 3 '#06a7c6', 4 '#38b99e', 5 '#92bf73', 6 '#d9ba56', 7 '#fcce2e', 8 '#f9fb0e')
set autoscale fix
set grid
set terminal png size 2184,1472 enhanced font "Helvetica,20"
set output 'ap130_base.png'
splot 'ap130_base_dgrid.txt' w pm3d, 'ap130_base_contour.txt' w l lc rgb "black"
set output
set terminal X11
The plot looks like this;
Is there a way to make this less 'spotty'?
Your input is much appreciated.

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...
