gnuplot

问题 It might be very simple, but I cannot find the specific answer to this: how can I plot the first vs the last and the second to last columns in several files whose column number is variable? is there something like plot "mydata.txt" using 1:-1? I've already tried to use tail, but I don´t know hot to specifically use it, and couldn´t make this answer Count columns in csv in gnuplot work neither :( Thanks! 回答1: An answer to Automatic series in gnuplot shows one possibility. But that doesn't work

问题 In some cases you might need to resample your data. How can this be done platform-independently with gnuplot? Below is one attempt. The dataset $Dummy contains the interpolated values, however, with a lot of unnecessary lines containing NaN . The dataset $DataResampled finally contains the desired data. My question is: can this be done simpler? The code: ### resampling data with linear interpolation reset session $Data <<EOD 0 1 1 4 2 10 5 15 10 5 20 11 EOD # get the x-range stats $Data u 1

问题 I have a datafile with position of a moving point in the following format. x1 y1 x2 y2 x3 y3 . . . I wish to make an animated trajectory with this data in gnuplot. How can I do that? I tried do for [i=1:20] { plot "temp.dat" every ::i using 1 : 2 w p } But it plots all the points in a single image, not an animation. What is the way of doing this? 回答1: While I was coding and got interrupted... @Ethan's answer already contains all the necessary ingredients, I post my answer nevertheless, with a

问题 What I basically want to do is basically the same as the solution to this question Gnuplot 5.2 splot: Multiple pm3d palette in one plot call , but which works with pm3d. If you read the comment to that answer, the answerer said that the solution does not work if he used pm3d. Also, would it be possible to define the palette in a simpler manner, such as set palette defined () ? 回答1: The development branch of gnuplot supports multiple named palettes. The method shown here, however, works on

问题 I saved a wireshark sniffer capture file as csv. All the elements are saved within the double quotation. I am trying to plot the graph over the same. csv file and the gnuplot code is given. All the values came up to a single xtic label. Can someone help me giving a workaround to plot using the doublequotes in the data file. data.csv "No.",Time",Source,Destination,Protocol "2",0.000252",192.168.1.183,224.0.0.251,MDNS "3",0.000553",192.168.1.183,224.0.0.251,MDNS "4",0.00102",192.168.1.183,224.0

问题 I would like to plot a pm3d map, where data points are not equidistant on the axis. Since the spacings for the x and y axis are identical, it is symmetrical, though. The problem is whenever a value is "NaN", all of the four surrounding rectangles are not plotted. In the data file below, this happens, for example, at (x,y)=(0.14,0.33) . If the value is not 'NaN', then the four rectangles reappear. I discovered this problem, when I tried to plot only the values >0 or <0, where the same happens.

问题 I have the code importing the data and plotting it but all the bars are purple and I want to change up the colors for each. Another issue I noticed is that it shows the file location on the graph and I don't want it on there. set title "Accuracy Plot for the FASP" set xlabel "Fucntion" set ylabel "(%)" set boxwidth 0.9 absolute set style fill solid 1.00 border lt -1 set key fixed right top vertical Right noreverse noenhanced autotitle nobox set style increment default set style histogram

问题 I have three different lines, where colours and their dashes means different things which I want on one plot, instead of three. How do I accomplish that? set datafile separator comma $sample <<EOD 2020-01-01,4,UK,Business 2020-02-01,4,UK,Business 2020-01-01,4,UK,Social 2020-02-01,15,UK,Social 2020-01-01,1,USA,Social 2020-02-01,25,USA,Social EOD set format x '%Y' set xdata time set timefmt "%Y-%m-%d" plot '$sample' u 1:2 title "UK/Business" with linespoints dt 3 lw 5 pt 7 lc "red" plot '

问题 I have a list of date+time start and stop that I would like to plot as bars. The X-axis should go from 00:00-23:59 with date on the Y-axis I tried plotting in gnuplot , but my skills are not good enough. The data is in the following format: Date Start Stop 06.03.2019 09:45 11:17 06.03.2019 14:40 15:20 07.03.2019 08:35 10:15 07.03.2019 14:05 14:45 08.03.2019 09:15 10:20 08.03.2019 13:55 14:45 09.03.2019 08:55 09:50 09.03.2019 13:15 14:36 10.03.2019 09:05 10:00 I would like to get a plot
