问题 I'm trying to plot a bundle of graphs that are currently stored like this : MyFile.txt "ID01" 1 2 3 4 5 "ID02" 3 4 5 6 7 8 9 "ID03" 4 3 1 2 3 4 such that there is one line titled "ID01" that shows the first row only, another line titled "ID02" and so on. Bonus points if lines are displayed in different colors. Any help is much appreciated! I got as far as this : plot for[blockIndex=0:3] "MyFile.txt" matrix index blockIndex every ::1 w lp title "".blockIndex which produces the below image if

问题 I am a mechanical engineer who has only limited knowledge in C programming. I wrote some code in order to make simulations, and I want to visualize the simulation results. At the moment I am using Dev-C for writing my codes. With fopen and fprintf commands I generate a .dat file which includes the results. Then I open GNUPLOT program and import my .dat file to plot the results. This takes time and I have to wait till the end of the simulation. Is there an easy way to connect my plotter with

问题 I am plotting a large number of bars and therefore I only mark the every nth xtic (as seen in the .dat file with " "). Here are the first 15 lines of my input ".dat" file: 1 150 " " 260 " " 340 " " 410 5 270 " " 280 " " 260 " " 370 " " 220 10 230 " " 340 " " 300 " " 200 " " 240 15 160 Plotting this data works fine. However, in my actual .dat file I have about 500k values to plot (500k boxes). Therefore I wanted to color every 10k box with a certain color (or in the example above, every 5th).

问题 Out of the blue, my Gnuplot has started having issues with the pdfcairo terminal. The font in the produced PDF files is jammed as if the width of the individual characters was set to zero. I am using Gnuplot 5.2.7 on Mac OS, installed via homebrew. Here, a minimal not-working example: reset set terminal pdfcairo set output "mnwe.pdf" set xlabel "Time t" set ylabel "sin(t)" plot [0:2*pi] sin(x) with lines notitle which produces the following output: I suspect that the font issue occurred after

问题 [Current] I am importing a text file in which the first column has simulation time (0~150) the second column has the delay (0.01~0.02). 1.000000 0.010007 1.000000 0.010010 2.000000 0.010013 2.000000 0.010016 . . . 149.000000 0.010045 149.000000 0.010048 150.000000 0.010052 150.000000 0.010055 which gives me the plot: [Desired] I need to plot an average line on it like shown in the following image with red line: 回答1: Here is a gnuplot only solution with sample data: set table "test.data" set

问题 I'm trying to plot something like this: set key top left box opaque set border back plot sin(x) but I want the key to have a different background color than the rest of the graph. For example, if the graph is white, I want to the key to have a grey background. Or something like that. I'm relatively new to Gnuplot, but I have looked in the manual and there doesn't seem to be a direct way to do this. Can someone suggest a solution? Thanks. 回答1: Yes, if you check help key , there seems to be no

问题 The location of the grid lines (parallel to Y-axis) at X-axis are defined at third row of a files, for example the third lines has the points # 0.00000000 0.08329780 0.11683890 0.20013670 0.23367770 I can get the Ymax from another file defined as FILE with set table $Dummy plot FILE u ($0==1?(Ymax=$2): NaN) w table # i have updated this line. This will be used only for height of the grid line. Here FILE is a data file with two coloum only which will be plotted in X-Y format. unset table How I
