问题 I have a .txt file contatning points which is look like following: ##x1 y1 x2 y2 123 567 798 900 788 900 87 89 .... I want to draw 2D diagram which link each pair in line of the .txt file using gnuplot. Edit1: I find this Draw points and lines in gnuplot, but I don't know how to use gnuplot in my case. Edit2: There is no limit for the diagram type. As I see here I could set terminal to png using following: set terminal png For line style I find this example here: set style line 1 lc rgb '

问题 i have a file with the following data the first field is UNIXTimestamp, 1351734672.095 25 1351734674.449 52 1351734676.638 612 1351734680.669 44 1351734681.121 16 1351734684.182 15 1351734684.386 17 1351734686.823 16 1351734689.807 22 1351734689.807 28 how do i load the x,y from this file to python? #!/usr/bin/env python from numpy import * import Gnuplot g = Gnuplot.Gnuplot() g.title('My Systems Plot') g.xlabel('Date') g.ylabel('Value') g('set term png') g('set out "output.png"') proc = open

问题 I understand this question is similar to Gnuplot: How to plot multiple time series from a binary format; however I've already set up an example which is slightly different, so hope it's OK to post (self-answer follows). I'm generating my binary data like this (see below for the genbindata.pl Perl script): $ perl genbindata.pl > bin.dat $ du -b bin.dat 234 bin.dat This binary file, bin.dat is formatted like this (first two rows are 1-based and 0-based index): >| 1 2 3 4 | 5 6 ... 104 |105 106

问题 My data file is a set of (x,y,z) points located around the axis origin. They represent points where a kind of measure has failed. These points are in this link. Gnuplot can plot them, set encoding iso_8859_1 set term postscript eps enhanced color size 4.7in,4in set xlabel "X" set ylabel "Y" set zlabel "Z" set output "test_gp.eps" set style line 1 lc rgb '#0060ad' pt 7 ps 0.5 lt 1 lw 0.5 # --- blue set style fill transparent solid 0.15 noborder splot "data.dat" u 1:2:3 w p ls 1 title "P_{error

问题 I'm absolutely new to gnuplot and did not find a working solution after googling. I have a data matrix looking something like this: A B C D E A 0 2 3 4 5 B 6 0 8 9 0 C 1 2 0 4 5 D 6 7 8 0 0 E 1 2 3 4 0 What I would like to do is plotting a heatmap with plot 'result.csv' matrix with image , with the x-axis labeled with A-E and the y-axis labeled with A-E. This matrix does not always have the same size, but the number of row always equals the number of cols and it's always labeled. Could

问题 I got a problem in Gnuplot 5.0, the dashtype index, such as ``set dashtype 1 (2,5,2,15)` in the manual. My question is: what do these numbers in parenthesis exactly mean? I tried to change them to get a feeling, but it would be great to know the exact meaning. My actual problem is, that simply using dashtype N , gives lines which look very different from the previous 4.6 version, unfortunately. I just try to reproduce the plots which were made in gnuplot 4.6. 回答1: Those are numerical pairs
