gnuplot

问题 I have a gnuplot script. My system is ubuntu 14.04. When In the terminal I type gnuplot myPlot . The plot will disappear. It is not remain on the screen. I this stack in saw similar question. But its system is windows. I want to know is there any solution for that on ubuntu 14.04 32 bit PS: when I use gnuplot> -- I mean when I do not use script file-- I see the diagram and it does not disappear. PS2 : this is my simple gnuplot script file : set boxwidth 0.5 set style fill solid plot "dataFile

问题 I know the command to plot circle in gnuplot: plot 'circle.txt' using 1:2:3 with circles Suppose if circle.txt contains n lines and each line contains ( centerX , centerY , radius ) of different circles, e.g.: #x y radius 0 0 1 1 1 2 2 2 3 How can I generate n images containing n different circles - one image per line? 回答1: This will work with gnuplot 4.4 and higher: gnuplot> n = "`awk 'END {print NR}' < circle.txt`" gnuplot> i=0; while i<n{set term wxt i; plot 'circle.txt' every ::i::i using

问题 I have a set of files named like this: qd-dPZ-z1-1nn.dat qd-dPZ-z2-1nn.dat qd-dPZ-z4-1nn.dat qd-dPZ-z8-1nn.dat qd-dPZ-z16-1nn.dat qd-dPZ-z32-1nn.dat qd-dPZ-z1-2nn.dat qd-dPZ-z2-2nn.dat qd-dPZ-z4-2nn.dat qd-dPZ-z8-2nn.dat I need to generate a graph for each file (from file qd-dPZ-z1-1nn.dat generate graph qd-dPZ-z1-1nn.ps from file qd-dPZ-z2-1nn.dat generate graph qd-dPZ-z2-1nn.ps and so on) So far, I´ve tried gnuplot> filenames = "qd-dPZ-z1-1nn.dat qd-dPZ-z2-1nn.dat qd-dPZ-z4-1nn.dat qd-dPZ

问题 i am plotting a tree in gnuplot as discussed here (How to plot tree/graph/web data on gnuplot?). However, i would like to include the edges weight of the tree, i.e. for each edge i have a number (e.g. 10, 20, 30, 40) that represents the edge weight. The figure below shows in red the edges weight that i want to plot in gnuplot (i added this using power point). Can anyone tell me how to plot edges with weight in gnuplot? 回答1: I would propose a slight variation on the answer which you mention in

问题 I have a problem with gnuplot. I've searched and I don't find the correct solution. I'm plotting some data arranged in three columns with the command splot , and the steps in x and y are different. The plot I get with: set view map splot 'data.dat' using 1:2:3 with points palette is: and I would like the white space to be filled, making each tile size adapt, avoiding interpolation. Some ideas are given here Reduce distance between points in splot. I've tryed http://gnuplot.sourceforge.net

问题 I would like to plot points in a 3d plot and create a mesh that could handle non rectangular data. To be more specific my data is data.dat -1 0 0 -1 1 0 0 -1 0 0 0 0 0 1 0 1 -1 0 1 0 0 and my gnuplot file plot.plt set dgrid3d 3,3 splot 'data.dat' w l pause -1 Unfortunately dgrid3d seems to make my data rectangular and a rectangular grid (actually a square grid) is plotted. Is there a way to plot a restricted envelope of my data ? Ideally I would like to plot the orthogonal convex hull of my

问题 I am using C++ to pipe commands to gnuplot using the following code: FILE *gnuplotPipe = popen("gnuplot -persist", "w"); // Open a pipe to gnuplot if (gnuplotPipe) { // If gnuplot is found fprintf(gnuplotPipe, "reset\n"); //gnuplot commands fprintf(gnuplotPipe, "n='500'\n"); fprintf(gnuplotPipe, "max='1500'\n"); fprintf(gnuplotPipe, "min='-1500\n"); fprintf(gnuplotPipe, "width=(max-min)/n\n"); fprintf(gnuplotPipe, "hist(x,width)=width*floor(x/width)+width/2.0\n"); fprintf(gnuplotPipe, "set

问题 I know this was asked before a while ago using images for points but I was wondering whether someone can provide more detailed help, or whether any recent changes in gnuplot make this easier? My question is slightly different and I didn't want to reopen a 6yo question I'm trying to produce a plot for a weather forecast similar to this: AIX weather widget screenshot I have some data from openweathermap's api, and an icon set - plotting the temp, rainfall, etc is trivial.. What I would like to

问题 I want to do simple graphing routines in Tcl/Tk like scatter plot, x-y plot, histograms. I am using Tcl/Tk 8.5.7. I found in Tcler's wiki that there are few options such as BLT which is not supported in Tcl/Tk 8.5+ Is there any Tcl/Tk interface to gnuplot or any widget to accomplish graphing? Please let me know about the choices for graphing routines in Tcl/Tk. 回答1: Gnuplot can indeed produce output that Tcl/Tk can consume. This page on the Tcler's Wiki describes how (though with some extra

问题 I could not find a solution to the following issue I am facing. All SO questions on multi-axis talk about line plots, but I am looking for histograms. The y-range for the bars are different, so one set of bars are not really seen because of the scale. Here is the data: Metric A B M1 0.613416301 0.543734744 M2 0.000195961 0.000100190 Here is the MWE: reset set term postscript eps size 5.5,4.5 enhanced color font 'Arial-Bold' 25 set out 'histplot.eps' set key right set style histogram cluster
