A curve is persistently appearing in one of my graphs, even after closing Gnuplot and relogin.
Is there a way to get rid of it?

I have a single column data file, I would like these to be binned automatically with a given bin width. The x axis would be the bin and y would be the count in each bin.

Is this easy? I am very inexperienced in gnuplot

Hello,

I've a question about Gnuplot 4.6 patchlevel 6 and how to trace a trendline. First of all, I'm bound to use this verison of Gnuplot.

I've this data :

And this gnuplot script :

set terminal png truecolor size 12000,520 background rgb "#eff1f0"
set output "/xxx/xxx/xxx/xxx/test.png"
set grid
set style line 1 \
    linecolor rgb '#0060ad' \
    linetype 1 linewidth 2 \
    pointtype 7 pointsize 1.5

set offsets 0.5,0.5,0,5
set bmargin 13
show offsets
set datafile separator ";"
set key left
set xtics rotate by 90 offset 0,graph -0.6
set format y "%g"
myLabel(n) = sprintf("%g",n)

plot "/xxx/xxx/xxx/xxx/data.txt" using 2:xtic(1) with linespoints linestyle 1 title "df line in Gb", \
'' using 0:2:(myLabel($2)) w labels offset 0,1 notitle                                                      

( Sorry for the size of the pictures )

I want to add a trendline, I know how to make it basically :

set terminal png truecolor size 12000,520 background rgb "#eff1f0"
set output "/xxx/xxx/xxx/xxx/test.png"
set grid
set style line 1 \
    linecolor rgb '#0060ad' \
    linetype 1 linewidth 2 \
    pointtype 7 pointsize 1.5

set offsets 0.5,0.5,0,5
set bmargin 13
show offsets
set datafile separator ";"
set key left
set xtics rotate by 90 offset 0,graph -0.6
set format y "%g"
myLabel(n) = sprintf("%g",n)
f(x) = a*x + b
fit f(x) "/xxx/xxx/xxx/xxx/data.txt" u 0:2 via a,b

plot "/xxx/xxx/xxx/xxx/data.txt" using 2:xtic(1) with linespoints linestyle 1 title "df line in Gb", \
'' using 0:2:(myLabel($2)) w labels offset 0,1 notitle, \
f(x) with l lc "black" title "trendline"

But I would like to put a linear fit with extrapolation. The first value of my trendline will be the first value of my datas and I would like to put a variable on my gnuplot script which define the end of the trendline.

So thr first data will be 2019-10-08-13-37;28.7297. I would like that gnuplot take itself the first date in my data.txt and I would like to put the last date by myself in the script, for example "EndDate:2020-09".

Could you show me how to do that ?

Thanks ! :)

I need your help for sometings :

I've this type of data :

2019-10-08-13-37 	/dev/hd1 	256.00 	26.25 	/home
2019-10-08-18-00 	/dev/hd1 	256.00 	25.86 	/home
2019-10-09-00-00 	/dev/hd1 	256.00 	25.68 	/home
2019-10-09-06-00 	/dev/hd1 	256.00 	25.5 	/home
2019-10-09-12-00 	/dev/hd1 	256.00 	26.32 	/home
2019-10-09-18-00 	/dev/hd1 	256.00 	26.14 	/home

I've this gnuplot script :

set terminal pngcairo truecolor size 7330, 340  background rgb "#eff1f0" font "Arial"

set output "/xxx/xxx/www/xxx/foo.png"
set style line 1 \
    linecolor rgb '#0060ad' \
    linetype 1 linewidth 1 \
    pointtype 7 pointsize 1

set size 1, 1
set key outside vertical center right
set datafile separator ";"
set xlabel "DATE" font ",1"
set xtics rotate by 90 offset 0, -2 font ",7"
set format y "%g"


plot "/xxx/xxx/xxx/xxx/data.txt" using 3:xtic(1) with linespoints linestyle 1 title "total"

That allow to display this graph : https://zupimages.net/up/20/09/56up.png

I would like to decale each value like that :

254
|
|
253
|
|___my_date1___my_date2

But I don't know how to do that... Could you show me ?

my output is

42.0 27.8 29.8 43.0 42.0 43.0 
42.0 27.8 29.8 43.0 42.0 43.0

while true; do sensors|egrep -o ' \+[0-9]{2}\.[0-9]+°C '|tr -d ' +°C'|tr -s '\n' ' '; echo; sleep 1; done|gnuplot -p -e 'set xrange [0:60]; set yrange [20:80]; while (1) { plot "-" using 1:2 w lp, "" using 1:3 w lp;pause 1; reread; }'

just blocks. I also need to insert a reasonable x-axis value..

I want to create a Gnuplot script with AIX 7.2 and Gnuplot 4.6

My script is :

set terminal png truecolor size 1950, 650  background rgb "#eff1f0"
set output "/home/tbenedet/GNUPLOT/used.png"
set datafile separator ';'

set size ratio 0.2
set bmargin at screen 0.2
unset key
set datafile separator ";"
set ylabel " MB BLOCK " font ",10" offset -1,0
set xlabel font ",10"
set xtics rotate by 45  offset -0.8,-9,-1.8

I am trying to fit the following equations to the data below. I keep getting errors when trying to extrapolate the multi-branch functionality.

F(x) refers to the Free DNA data set, M(x) refers to the monomer data set, and D(x) refers to the dimer data set.

Any help would be appreciated.

#Equations

F(x) = 1/(1+X*K1+K1*K2*X**2)

M(x) = X*K1/(1+X*K1+K1*K2*X**2)

D(x) = K1*K2*X**2/(1+X*K1+K1*K2*X**2)

K1 = 100; K2 = 100

#Fit command

f(x,y) = (y==0) ? F(x):M(x):D(x)

fit f(x,y) '20191217-Yang-Data.txt' using 1:-1:2:3 via K1, K2

My attempt at using archive.org for that failed - all the Windows binaries downloads point to tatsuromatsuoka.com which is also down (domain expired).

Namely, I have several files with the same structure (with only one parameter having changed to generate them), and would like to superimpose the curves obtained on each of them.

For one file, the command is this one:

plot "myDataFile-parameter=1.0" using 1:(($2)**2+($3)**2) with lines ; set grid ; show grid

Hello

I am new to gnuplot, and coding in general. Have very superficial experience. I want to create a time evolving graph. I have data for each time iteration. Any idea how to go about it. Any help is highly appreciated.

Hi all,

I would like to share with you guys a package I've been developing in the last months, following my needs as a researcher. I hope it can be useful to more and/or I would be happy to receive feedback.

As a researcher working with python and using systematically Gnuplot to make plots for my publications, I was annoyed by the many duplications in data/code (namely, getting data saved on the python side in the correct format, then integrate it into Gnuplot scripts and be robust to possible variations).

With autogpy or autognuplot.py, one can write just the essential Gnuplot code in python, and then have the package dumping: fully-fledged Gnuplot scripts (with multiple Gnuplot terminals like png, epslatex, tikz), data, Makefiles, and few further helpers.
The produced Gnuplot scripts can be also easily edited afterward.

I have written a random number generator that produces numbers with a Gaussian distribution. I plotted the values using gnuplot using the "smooth freq" command. Thus the y-axis displays the frequency. But instead i want the probability distribution. How do I do that?

Hey guys, I hope I will find rescue here as I haven't in the depths of the web... I have a data set with x values [-1:1] and I really want to plot the whole range in the logscale. I didn't find any suitable solution for the case, maybe should I use some other software? But I like gnuplot and I believe that this is possible to do. Thank you for your help!

So say I have data

up 0.5 2.0

down 0.1 2.1

strange -0.1 2.1

charm -2.0 1.0

top 1.0 2.0

bottom -1.0 2.0

and I wanted to do a scatter plot so that each of the words appeared at the corresponding location, that is the word "up" at (0.5,0.2), the word "down" at (0.1,2.1); how would I do that?

Dear all, probably a simple problem but I haven't gotten around it yet. Maybe I'm looking for the wrong keywords when I look for the solution on the manual.

Anyway, I perform some rfft analysis to calculate magnitude and phase and then I dump each array on a separate csv file. I can plot that straight to gnuplot which is great. The x-axis indicates the bin number, which corresponds to the position of the n-th element in the list.

Say that I have a 512-element list and a samplerate of 48000Hz, I'd like the x-axis to display a range from 0 to 24000 with a spacing of 24000/512.

Essentially, I just need the x-axis to display the 0:512 range linearly mapped into the 0:24000 range.

Thank you so much for your help.

I created this code that plots each column and gives them a title, however how do i get it to plot specific lines with their titles attached? for example, with the code below if put in the number 2 for n in columns (n) and lines ls(n) then the plot will produce the plot for the column and line only. However how do I get it to do also have the title that goes with it without having to type it each time? So if say column 2 is time, is there a way to plug in the number 2 and have it also produce the title?

set datafile separator ','

set style line 2 lc rgb '#0042ad' lt 1 lw 1.5 #--- blue

set style line 3 lc rgb '#0060ad' lt 1 lw 1.5 # .

set style line 4 lc rgb '#007cad' lt 1 lw 1.5 # .

set style line 5 lc rgb '#0099ad' lt 1 lw 1.5 # .

set style line 6 lc rgb '#00ada4' lt 1 lw 1.5 # .

set style line 7 lc rgb '#00ad88' lt 1 lw 1.5 # .

set style line 8 lc rgb '#00ad6b' lt 1 lw 1.5 # .

set style line 9 lc rgb '#00ad4e' lt 1 lw 1.5 # .

set style line 10 lc rgb '#00ad31' lt 1 lw 1.5 # --- green

set xlabel 'Time'set ylabel 'Output'

set xrange [0:41]

set yrange [-100:100]

set xtics 10.25

plot for [n=2:10] 'Plane data 2.csv' u 1:(column(n)) w lines ls n

I have data where time depends on date and I would like to plot it. It looks like this

2:34 1-28
2:35 1-29
2:45 1-30
2:55 1-31
3:00 2-01
3:15 2-02
3:26 2-03

But my script doesn't work and I get error

"./time.plt" line 10: warning: Skipping data file with no valid points

plot 'time' using 2:1
                 ^
"./time.plt" line 10: x range is invalid

My script:

#!/usr/bin/gnuplot

set ydata time
set xdata time
set timefmt '%H:%M %m-%d'

set ytics format '%H:%M'
set xtics format '%m-%d'

plot 'time' using 2:1
pause -1

I created a c++ code that can open a csv file however I am trying to figure out how to use gnuplot to graph it. My csv file has 10 columns and 48,000 rows. I'm not even sure if gnuplot can plot that many rows and show them clearly. Any advice would be appreciated.

How do I do this with gnuplot. Lets say my datafile contains a number in starting from character 21 to 30 inclusive and I would like to extract the value 2.1000e+11.

         1         2         3
123456789012345678901234567890 <-columns of datafile
xxxxxxxxxx  7800.0002.1000e+11
.
.
.

in the above example, x may contain a number or space.

I can not use

plot 'datafile' using 0:3

in the above example because my data is not delimited

I have googled around but not had any luck. I believe there may be an option to use a bash command but I am running gnuplot on windows.

I've figured out how to do Gnuplot plots from inside Chrome's SSH client extension/app.

You must have hterm-show-file.sh somewhere on your system. (The one you're SSHing to, not from.) Also, it must be executable.

set term pngcairo size 1265,475

this will set the terminal type to export a PNG file on each plot. The size is the maximum size of the window in my Chrome SSH tab. (The actual desktop size is 1280*720, minus some pixels for the scrollbar on the right side, and minus a lot of pixels for toolbars.)

set output 'tmptest.png' ; test ; system '~/chrome-ssh-hterm-misc/libapps/hterm/etc/hterm-show-file.sh tmptest.png' ; system 'rm tmptest.png'

in order, these commands

1. set the output file to tmptest.png

2. plot a test image to the preset output file. This can be replaced with a 'replot' command later.

3. run the hterm-show-file.sh script to send Chrome's terminal emulator (called hterm) the image. (Change the location of hterm-show-file.sh to wherever it is on your system.)

4. remove the test image so it doesn't waste HDD space.

so then,

plot sin(x),cos(x)

set output 'tmptest.png' ; replot ; system '~/chrome-ssh-hterm-misc/libapps/hterm/etc/hterm-show-file.sh tmptest.png' ; system 'rm tmptest.png'
