I set the range in my plot like such set yrange[ 0.000 : 0.040 ] and the graph's interval is 0.005 on the y-axis. The y-axis reads like 0.04 0.035 0.03 0.025 0.02 0.015 0.01 0.005 0 on the side of the graph. This looks totally inconsistent. How can I...

The data file contains values in the following format: 0 0 50 0 1 70 1 0 40 1 1 70 2 0 110 2 1 60 3 0 60 3 1 120 4 0 50 4 1 50 5 0 70 5 1 70 This is a code snippet...

Plotting in Gnuplot: For example if one tries to both set the datapoint type and the errorbars into one command, there's a conflict of "with" arguments, i.e.: plot "test.csv" using 1:2:3 with points pointtype 5 with yerrorbars The error message is as follows: duplicated or contradicting arguments in plot options....

I'm trying to plot a heat map in Gnuplot: set view map set size square set cbrange [0:1] splot "input.dat" 1:4:8 w pm3d But I want to skip the rows with the data in the first & fourth column in a particular range without changing xrange and yrange. How can...

Im plotting one picture with 4 different graphs using gnuplot. Labels for their x and y axes have the same meaning. If Im plotting it like this: set multiplot layout 2,2 rowsfirst set xlabel "x" set ylabel "y" set title offset -3,-3 set xrange [20:70] set yrange [0:15000] set title...

Data Year Water Power Wood Power 2025 58.1 41.9 2035 55.8 44.2 2050 50.6 49.4 Code set style histogram columnstacked; set terminal qt size 560,270; set grid; set offset 1,1,0,0; plot 'RES.dat' u 1:3; which gives where it somehow omits the first sentence of the command. I tried to set...

Does anybody know how to extract some data of smooth cspline curve for a given data? For instance, there is a data file which has 2 columns corresponding to x and y values. I can draw the data with smooth cpline curve by the following commands p 'data' w lp,...

I can connect the dots of a data file by including with lines in the plot command. Is there a way to set this fixed (I was hoping for set with lines) so I don't have to explicitly include it in every call of plot?

I have recently upgraded to Debian jessie, meaning that I have upgraded from gnuplot 4.6.0 to gnuplot 4.6.6 (issue is the same with gnuplot 5.0). I have bash scripts automating things, and launching gnuplot terminal. I was using either: gnuplot -persist -e "set title 'Sine curve'; plot sin(x)" or gnuplot...

I use FORTRAN 77 code to generate data (saved as filename.dat) of simple physics situations containing x-y co-ordinates like a projectile. My data files usually have 2 or 3 columns like so: 1 1 2 2 3 3 4 4 5 5 I can plot (2d and 3d) using Gnuplot...

I have to make graph with gnuplot from some kind of input data. There is date, score and count for every entry. Graph should be with x axis representing date (I'll probably have question for that in the future too :/ ), y axis score and count should be represented...

I am plotting a histogram rowstacked very similar to this graph (the last one on this page) : What I would like to do is to have different colors for each year bin. This colors would repeat from a newhistogram to another. I have not yet found a way to...

I've got two datasets referring to the same process executed in two different ways. The execution A is slower than the execution B with respect to real time, but the two graphs represent the same phenomena.. I can plot the two together as follows: plot 'A' using 1:2, 'B' using...

I have a file with 1600 columns. plot "file" using 1:999 title columnhead(999) plots column 999, but plot "file" using 1:1000 title columnhead(1000) produces column 100 instead of 1000, producing the same result as plot "file" using 1:100 title columnhead(100) Apparently large column numbers are wrapped. Is there a work-around...

I want to run either persistent gnuplot or write output to file. This behavior should be affected by passing variable. Here is my test.plg: #!/usr/bin/gnuplot -p if (exists("file")) set term png; set output "test.png"; if (!exists("name")) exit; set title name plot sin(x) If I run script this way it is...
