gnuplot

问题 I want to place several plots with gnuplot in following way: +------------------------+ |plot1 | | | +------------------------+ +----------++------------+ |plot2 ||plot3 | | || | +----------++------------+ +----------++------------+ |plot4 ||plot5 | | || | +----------++------------+ Simple nxm layouts can be achieved via set multiplot layout n,m (see these demos for illustration on the official website). matplotlib offers much more advanced possibilites as you can see in the documentation:

问题 Why when i make this code of gnuplot it's work : set terminal postscript enhanced color set output '../figs/ins_local.ps' set title "Result" set logscale y set xrange [50:100] set xtics 5 #set xlabel "Insertion" #set ylabel "Time (in microseconds) " plot sin(x) but when i change plot sin(x) with : plot "../myFile.final" with lines title "Somethings" lw 3 linecolor rgb "#29CC6A" i have this error : plot "../myFile.final" with lines title "Somethings" lw 3 linecolor rgb "#29CC6A" ^ "local

问题 How one could make resulting output of scaling over z axis symmetric over xy plane: zmax = zmin, keeping autoscale on z axis turning on? (GNUplot 5.0) resulting graph - 3d-polar.png Is there this possibility in GNUplot or only fixed range of cbrange can be used? the example that is used for polar heatmap plot: reset set terminal pngcairo size 800,800 set output '3d-polar.png' set lmargin at screen 0.05 set rmargin at screen 0.85 set bmargin at screen 0.1 set tmargin at screen 0.9 set pm3d map

问题 I am new to gnuplot and using Ubuntu 12.04. I want to create a graph on the fly when the information is coming in. So i have a data.dat file which looks like: time server1 server2 0 0 0 1 2000 3000 2 3000 4000 3 4000 5000 After that i have a script file, loop.plt, that is used to reread the file: pause 2 replot reread And finally, the command I use in in a bash file: gnuplot -persist -e "plot 'data.dat'" loop.plt The result comes back as dots - not a line that I expected. But this is only for

问题 I need to plot a couple of curves in a single window. Using for loop in bash shell I've been able to plot them on separate files , but no success in sketching them on a single pic. I would appreciate it if you can guide me on how to resolve this issue. I tried to implement the example in thie link for loop inside gnuplot? but it gives me an error saying: ':' expected .I have gnuplot 4.2 installed. Thanks, #!/bin/bash for Counter in {1..9}; do FILE="dataFile"$Counter".data" gnuplot <<EOF set

问题 Contour lines generated by gnuplot can look pretty strange (unexpected) if you do not set both samples and isosamples to appropriate values. I struggled for hours to find out how exactly set samples and set isosamples affect the appearance of contour lines, however, all I observed is that setting both to sufficiently large values will generate good-looking contours. Still, I want to understand how exactly this works. What is the difference between set samples and set isosamples in the context

问题 I want to create a Perl (or Bash) script to create and plot data on-the-fly. That means I want to extract data from a log-file file.log , ideally don't write a tmp-file (if it's only possible with a tmp-file, this would be fine too) and plot with Gnuplot. As the logfile is growing, I want to see the additional information in the plot. See this question for similar topic. For Perl, what I have so far is this script: #!/usr/bin/perl use strict; use warnings; my $path = "file.log"; my @grepped;

问题 I'm sure the answer is obvious but I can't find it without looking at the source. What is gnuplot's internal representation of floating point numbers? Is it the platform's double ? Does it use its own internal representation? Can it do arbitrary precision? 回答1: A quick google search will turn up that calculations are done in double precision whenever possible, however, there's a little sublety going on here. The range of an IEEE double precision number should go up to more than 1.797e308 ,
