I have a file (called print_1012720.txt) that looks like the text shown below.

I am running the following commands in bash.
gnuplot
reset
set terminal png
set xdata time
set timefmt "%d/%m/%Y %H:%M:%S"
set format x "%H:%M"
set xlabel "time"
set ylabel "highest seq number"
set yrange [0:65535]
set title "seq number over time"
set key reverse Left outside
set grid
set style data linespoints
plot "print_1012720" using 1:2 title "Flow 1"
It gives garbage in my shell. I suspect that it is the spacing between the columns that is causing this. However if I correct the spacing then the file is correctly plotted. Any clue how this can be rectified?
I suspect your main problem is that you are not setting an output. After your set terminal command you should set an output file, otherwise gnuplot will spit out the .png to your terminal, which looks like gibberish. Try putting the following in a file (saved as 'plot.plt' for instance) and then run gnuplot plot.plt at the bash command line.
set terminal png
set output 'output.png'
set xdata time
set timefmt "%s"
set format x "%H:%M"
set xlabel "time"
set ylabel "highest seq number"
set title "seq number over time"
set key reverse Left outside
set grid
set style data linespoints
plot "print_1012720.txt" using 1:2 title "Flow 1"
Creating a plot file this way will save you a lot of time typing at the gnuplot command line.
A couple of other comments:
1) You set your yrange to be 0:65535 when your y values from the datafile are much larger.
2) It looks like you are trying to extract a time in UNIX format from the first column in your datafile. For this you would want the line set timefmt '%s' as I have above. However, the time data in the data file appear to be all over the place, as do the y data.
3) You do not need the reset command at the beginning, since running gnuplot this way will create a new instance of gnuplot, so there will be nothing to reset.
4) You also had 'print_1012720' without the '.txt' extension; I'm not sure this was an error on your part.

I don't know why but I have an error. When I write all this things in terminal everything is ok, but when I use script I have this error
gnuplot> load wykres_sin.gp
internal error : STRING operator applied to undefined or non-STRING variable
This is my script
# Skrypt gnuplot
plot sin(x) w l
set title "Wykres sinusa od wartosci kata"
set xlabel "Wartosc kata (stopnie)"
set ylabel "Wartość sinusa"
set xrange [0:750]
set yrange [-1.2:1.2]
set term png large size 800,600
set output "sin.png"
replot
exit
You need quotes around the file name:
gnuplot> load "wykres_sin.gp"
I am constructing a normal X/Y data plot using column data from a .txt data file. The graph plots well (see general code below).
I am wondering if it is possible to extract and use a System time in conjunction with the logged data in the .txt file?
This is in order to produce an X/Y plot with Y being the data from column [x] from the .txt file and the x-axis being an extracted system time point ??
The system time is not part of the log file.
The data string contained within the text file looks like this and is ; delimited: 221.5;65.9;-22.9;0;22.1
Code to generate the plot:
set multiplot layout 5,1
set title "Plot 1"
unset key
plot "data.txt" using 1 with linespoints ls 1
set title "Plot 2"
unset key
plot "data.txt" using 2 with linespoints ls 2
......
unset multiplot
In other words, for each data .txt file column point I would like to attach a system time giving as "Plot 1" {sys.time[x],221.5} and for "Plot 2" {sys.time[x],65.9}.
The next row of file data points delimited by ; will have another system time attached to each of them.
Thanks
I am still a bit guessing, but your image made it a bit more clear.
Maybe we can use this for further tweaking.

The code:
### adding time data afterwards
reset session
FILE = "data.txt"
set datafile separator ";"
set xdata time
set timefmt "%d.%m.%Y %H:%M"
set format x "%d.%m."
TimeIntervalInSeconds = 3600*24
StartTime = "01.01.2019 12:00"
set ytics 0.5
set multiplot layout 5,1
do for [i=1:5] {
set title sprintf("Plot %d",i)
plot FILE using (StartTime+$0*TimeIntervalInSeconds):i w lp lt i notitle
}
unset multiplot
### end of code
Result:
I have two different text files which have a data column and a value column each. Ĩ wanted to plot both using a 'plot for' loop but I wanted to changed the name of the output to match the file I'm plotting. Right now my code looks like this:
set terminal postscript eps color
set out "test.eps"
set size 0.6
set multiplot
set xdata time
set timefmt "%Y-%m"
set format x "%b\n%y"
set xtics "2004-01", 12*2629746, "2016-12"
filenames = 'ArcheryData.txt CanyoningData.txt'
plot for [file in filenames] file u 1:2 w l title file
What I get now is the test.eps file which has the two data files plotted in the same graph.
In that case, you might use the do loop as:
set terminal postscript eps color
set size 0.6
set xdata time
set timefmt "%Y-%m"
set format x "%b\n%y"
set xtics "2004-01", 12*2629746, "2016-12"
do for [ name in "ArcheryData CanyoningData" ]{
set output name.".eps"
plot name.".txt" u 1:2 w l title name
}
Alternatively, the variable name could be specified when invoking Gnuplot, thus with a script as:
set terminal postscript eps color
set size 0.6
set xdata time
set timefmt "%Y-%m"
set format x "%b\n%y"
set xtics "2004-01", 12*2629746, "2016-12"
set output name.".eps"
plot name.".txt" u 1:2 w l title name
one might then use it as gnuplot -e "name='ArcheryData';" fig.gpl
I'm trying something very simple ...
#!/usr/bin/gnuplot
reset
filename = "something_or_other"
set terminal pngcairo dashed size 800,400 enhanced font 'Verdana,10'
set output filename.".png"
set title filename."\n"
set xlabel "probably time"
set ylabel "probably something else" offset graph 0.2,0.6 rotate by 0
plot filename.".dat" using 1:2 lc rgb "#00E80000" title "measurements"
!display filename.".png"
except filename stays just like that and doesn't get interpreted as a string.
How do I get this working?
The exlamation mark ! at the beginning of the line makes gnuplot send this whole line as it is to a shell. So, here you cannot use any gnuplot variables and string concatenation. For this you can use system():
system(sprintf("display %s.png", filename))
I have a handy script that is running ab and generating plot afterwards. However there is a problem, it shows me every point (which is good), however I would like to see also the average "line" between them. I will show more in the picture.
So is there any way to add the median/medium ranger on top?
Script
#!/usr/local/bin/gnuplot
set terminal jpeg size 1280,720
set size 1, 1
set output OUTPUT
set title OUTPUT
set key left top
set grid y
set xdata time
set timefmt "%s"
set format x "%S"
set xlabel 'seconds'
set ylabel "response time (ms)"
set datafile separator '\t'
plot INPUT every ::2 using 2:5 title 'response time' with points
exit
Ouptut
Output (what I would like to have)
That can be done with the smooth unique option:
This makes the data monotonic in x; points with the same x-value are replaced by
a single point having the average y-value. The resulting points are then connected by straight line segments.
plot INPUT every ::2 using 2:5 title 'response time' with points,\
'' every ::2 using 2:5 smooth unique title 'average' with lines
