gnuplot

问题 I am trying generate a pie chart using GNUPLOT, I have already generate the plot, and I have assigned colour to the legend using an array. This is the code, I have used this question as reference script.sh #!/usr/bin/gnuplot set terminal pngcairo nocrop enhanced size 800,400 font "Siemens Sans,8" set output 'output.png' filename = 'source.dat' rowi = 1 rowf = 2 # obtain sum(column(2)) from rows `rowi` to `rowf` set datafile separator ',' stats filename u 2 every ::rowi::rowf noout prefix "A"

问题 I want to make a smooth line over histograms. So far I have tried all the smooth functions but I am not able to get the result. For the histograms I am using: plot "file.scatter" u (hist($2,width)):(1.0) smooth freq w boxes notitle and the result is: But when I ask gnuplot to draw a smooth line over these: plot "file.scatter" u (hist($2,width)):(1.0) smooth freq w l notitle I get: I want the line plot to look smooth like a probability density function(of course the values will have to be

问题 I have the following working code using _popen, on windows, m_pGNUPlot = _popen("/gnuplot/bin/gnuplot.exe", "w"); fprintf(m_pGNUPlot, "set term win\n"); fprintf(m_pGNUPlot, "set term pngcairo\n"); fprintf(m_pGNUPlot, "plot \"\Data.txt\" using 1:2 notitle\n"); fprintf(m_pGNUPlot, "set output \"\Out.png\"\n"); fprintf(m_pGNUPlot, "replot\n"); fflush(m_pGNUPlot); But the problem with this is that cmd window keeps poping up, and there is no way to prevent that (Link) So, I write the equivalent

问题 I would like to know how the y can take value from the x (the x store the dates) i have the following dates 13/3/2014 218.11.11 12/4/2014 218.37.12 5/5/2014 218.31.34 7/5/2015 218.31.10 23/5/2014 218.32.21 4/6/2014 218.41.14 we have these dates and these ips i want store the ips in months example: 5/2014 - 3 IPS in gnuplot the graph i want to print every how much ips has every month here is what i have until now set xlabel 'Date' set title 'Gnuplot test graph' set ylabel 'IPS' set terminal

问题 Is it possible to plot the surface of the Cusp Catastrophe with Gnuplot? Here's a comparable plot. The catastrophe is mathematically described by: V = x^4 + a*x^2 + b*x (Wikipedia, see above) The surface is describes by: 0 = a + b*y – y^3 I'm a gnu plot beginner, so I'd be really grateful for an example with source code. (I study psychology and I need this plot for an essay about a clinical theory: the cusp catastrophe is used to describe changes of mood, that seem to appear more sudden and

问题 In LuaJIT or in the Torch REPL, I run the commands require 'gnuplot' gnuplot.figure() and I get the error "Gnuplot terminal is not set". I tried using gnuplot.setterm() with some guesses such as 'x11' and 'qt' as arguments, but get the error "gnuplot does not seem to have this term". Is there somewhere I can get a list of terminal emulators/graphics backends available to gnuplot? Or alternatively, are these errors indicative of some other problem? 回答1: It turns out that you get this error if

问题 I have been unsuccessful with other using hist plot. A simple problem would be using the following data: age range - frequency - central band width - bin width - height (respectively) 1-4 - 30 - 2.5 - 3 - 10 5-6 - 20 - 5.5 - 1 - 20 7-17 - 30 - 12 - 10 - 3 With age along the X axis, with a linear scale, so the bin width for 1-4 would be 3, with height 10, bin width for 5-6 would be 1 with height of 20, and 7-17 would be 10 and the height would be 3. How would can I place these data into a Word
