Hi there, It's the first time I am using gnuplot to plot a graph and I watched all sorts of tutorials and advices on google but I just can't find a good solution! Let me try to explain what the problem is... The experiment: I have a microphone and a speaker in closed box. The speaker is...

\sum_{k=0}^{∞} (t-2k) [u(t-2k)-u(t-2(k+1))] = f(t) where u is the step function and the graph of this is supposed to be 45 degree lines repeating to infinity. Sort of like / / / / / / / / / ad infinitum. I took this equation out of this lecture note on page 10. Fig 5.4 is supposedly the graph...

I'm hoping someone can help me with the following problem. I have a .p file for generating a .eps file using gnuplot. I want both the y-axis label and the y-axis tics to be formatted using LaTeX. Getting this done is no problem. The problem I am having is that having both of these options...

Hello with gnuplot I need to have 2d contour plot from a file (say ss.dat) with three column, first and secend columns are X and Y respectively and the third column is magnitude (I need to have this magnitude with labels on it in 2d plot). Thanks in advance Hamid

I would like the frame in a gnuplot plot to be slightly larger than the range of x and y. For those who know e.g. SAS, there it can be specified with "offset" in the axis statement. Is there something similar in gnuplot? (Obviously it would be possible to restrict the range of the function...

I want to include graphics in a latex document, so I used various terminal (png, jpg) in gnuplot but when I include in latex, the result it isn't very good...i would coloured graph , so which terminal i can use? what pagkage i have to include in tex file? Thanks for helpers

Dear Forum I would like to establish a workflow of how to include .eps graphics generated with gnuplot into Latex documents and it would be great if other could contribute to this. At the moment its like this. I plot some data with gnuplot and save it to a .eps file. However, the "white-space"...

Dear All, I am using gnuplot to make plots from data files generated using a fortran program. Those data files are basically big lists of 3d coordinates, just like like (not my real data, just an example): 10.0 1.00 0.01 20.0 1.00 0.14 ... So, when I use splot, I...

Hi! I am looking for some help using Derive. I have a differential equation, you can see it in the third image (I wanted to use LaTeX to render it but apparently I can't post LaTeX in this section of the forum). The value of lambda is given in the first image. I know the function...

Hello, I have currently written a Fortran 77 simulation program that I need to display graphically for each timestep. So far it calls the system to have gnuplot open an include file that has the gnuplot script to plot from my data files and produce a jpeg. What I would like to do is have it...

Hi all I badly need some help... I plot a file output1.txt in the following way :: gnuplot> plot "output1.txt" using 1:2 with lines, \ plot "output1.txt" using 1:3 with lines BUT now I have many data files, output1.txt, output2.txt, output3.txt, ...,... ,output1000.txt I need to...

Hi, I'm currently working on a C program where I have a huge 2d array that changes with time, so in the end, what I have is a 3d array (double 25*24000*100) in a plain text file (about 700MB). I tried to import with Mathematica7 as a "Table" but after a long time (about 15 minutes) the kernel...

Hey, this might be the wrong place to ask this question but I have a few problems using gnuplot. The problem is that when using the epslatex terminal my labels on the axis dissapears. This is the code I am using set terminal latex or epslatex color or wxt set output "psifunc.tex" h =...

Is there an easy way to change your y-variable in Gnuplot to ln y without changing the source data file? I already tried "set log y" but that only changed the y-axis scale, not the actual y-values. Right now I'm plotting an exponential decay and I wanted to make it a linear graph (lny vs...

Hi everybody, 1) It is possible to fill region somehow on one side of a parametric curve with gnuplot? 2) It is possible to do multiple parametric plots with the command "plot for [i=1:10] ..."? 3) How can display calligraphic fonts with gnuplot? 4) How can I use points which are larger than...

I'm trying to combine several contour plots together onto the same graph in gnuplot. I know that I can just do something along the lines of splot "file1.dat" u 1:2:3 w lines, "file2.dat" u 1:2:3 w lines set contour base set no surface set view 0,0 However, when I do that, the data from...

Hi, I have a major problem with gnuplot, this is what happens: gnuplot> plot "results.data" using 1:2 with lines works fine, but when I want to make another plot like: gnuplot> plot "results.data" using 1:3 with lines the plot window freezes and when I try to close it says something...

hello. I have a fortran code that has data points as output. How do I get fortran to plot these data points using gnuplot? Is there a way to call the external program from within fortran? I am using fortran95, gfortran compiler. I'm on a windows machine, but I'm connected remotely to...

I have a simple question about Gnuplot: How do I send my output data to a different directory than my working (current) directory? I'd rather not have my input and output data in the same directory.

I've been trying for a bit to get gnuplot to run on my mac but it doesn't seem to work properly. I can get it to run but it doesn't seem to recognize x11 or aquaterm for some reason so I can't actually display and plots. When I type set term it brings up a list of available terms but neither of...

Among the demos at the gnuplot website, I saw this - http://gnuplot.sourceforge.net/demo/steps.1.gnu, but it does not make much sense to me. :( Could someone tell me how to plot step functions from the command line, just like you would the usual functions? Specifically, I'd like to plot...

Hi, I've searched endlessly for an answer to this seemingly simple question, without success. I am fitting a lot of data and I am plotting the data and the fit on the same graph. I would like to have gnuplot automatically add the function (with the values determined by the fit) to the legend...

I want to plot in gnuplot the function , with the range being: 0<z<3 -5<x<5 -5<y<5 What is the command? Thanks in advance, fellows.

I managed to lay my grubby mitts on Maxima about a month ago (fantastic program), but having no prior knowledge of CAS software or programming I am stuggling trying to figure out how to draw piecewise defined functions either through maxima itself or the GNUplot command line window (I prefer the...

Hi All, I'm totally, competely and absolutely lost on how to use Gnuplot! I use Windows XP and I downloaded the zipped flie gnuplot-4.0.0.tar and unzipped it. (So, is the first step right? :confused: ) Now what do I next? I apologise for this apparently simple question, but I grew up in...
