Window dimensions of the wxt terminal in gnuplot

I'm trying to set the size of a wxt terminal window using gnuplot v4.2 gnuplot> set terminal wxt size 600,600 Terminal type set to 'wxt' undefined variable: size Even more frustrating is that wxt does not respect the -geometry flag like the x11 terminal. Note: I've tried 600,800 and 600x800 both don't work. % gnuplot --version gnuplot 4.2 patchlevel 4

Can gnuplot split data?

I have some data in the following format: 10.0 1 a 2 10.2 2 b 2 10.4 3 a 2 10.6 4 b 2 10.8 4 c 10 11.0 4 c 20 ... where the third column basically indicates belonging to a 'separate' dataset; and so I would like to show, say, those samples belonging to 'a' in red, those belonging to 'b' in blue etc (using gnuplot Version 4.4 patchlevel 2). I managed to somehow get the 'sample' style as a mix between 'impulses' and 'point' styles; and via Choosing line type and color in Gnuplot 4.0, managed t

How to plot specific rows in GNUplot

I have a two-column file which has 1000000 entries, that is 1000000 rows, however I don't want to plot all the data, I just want to plot the points every 100 lines? How to do this in gnuplot? Also, is it possible to specify some particular rows to plot in gnuplot?

In gnuplot for Windows, how can I list the files in the current/working directory?

I am running gnuplot version 4.6 (patchlevel 0) for Windows. The Windows version of this program provides a console or command prompt interface, similar to a bash shell in Unix/Linux or the DOS Command Prompt in Windows. Some commands in gnuplot for Windows are similar to those in Unix/Linux or DOS. For example, pwd prints the current/working directory. Also, cd changes the directory, so I can use commands like cd 'C:\Documents and Settings'. However, I have oddly not been able to figure o

gnuplot, graphing individual occurrences over a time period

Gnuplot conditional on terminal type (or 'set' variable in general) / read a 'set' variable?

I have a series of gnuplot scripts which I have developed using the default 'qt' terminal on my OS X system. This has the convenient feature of closing the closing the qt window when the script completes, so I added: pause mouse "mouse button 2 or 3 to close\n"; Later in development I want to output to pdf, but now the pause hangs my command line terminal until I hit return. I wanted to do: set terminal pdf ... if (terminal eq qt) pause mouse "mouse button 2 or 3 to close\n"; but this gi

gnuplot: fill area curve keeping tics on top

in gnuplot, when you try to fill an area under a curve, the tics of both axes are hinded behind the solid area. Is there any way to give them to the front? I am using postcript terminal, where no transparent features are allowed (i guess) Thanks

gnuplot gives extraordinary large error estimates

Although the fit was fairly good, gnuplot returned extremely high errors: Final set of parameters Asymptotic Standard Error ======================= ========================== A = 1.76654e-11 +/- 2.589e-06 (1.465e+07%) g = 0.000929911 +/- 1.006e-05 (1.082%) offset = 0.831727 +/- 0.005273 (0.634%) x0 = 25.7152 +/- 3768

GNUPlot: Animating a plane defined by three points

So I need to plot planes (as in, they HAVE to be FLAT) defined by three points which all come from my equation. I can redefine the code such that there is a space between the three points. I choose not to. I just added the comments for clarity of where the points are divided.

Gnuplot Label on x axis always out of the plot

Histograms have no problem like this; whenever using boxerrorbars, always a bar placed outside the plot...

Stop gnuplot interpolating heatmaps

I am trying to plot some data as a heat map in gnuplot. My data is a ".txt" file with three columns. The first two columns are the independent variables and the third is the output. E.g, a simplified example: 0.00 0.00 11.9 0.00 0.50 0.01 0.50 0.00 4.5 0.50 0.50 20.0 gnuplot> set view map; set dgrid3d; splot "output.txt" using 1:2:3 with pm3d I expect to get a 2*2 array of squares with colours according to their value. Instead, I think gnuplot has interpolated the values as regardless of

How to get contour or surface plot form datafile (with gnuplot)?

I would like to use gnuplot to plot my 2d function ch(x,y). My datafile is structured in this way: x1 y1 ch(x1,y1) x2 x2 ch(x2,y2) x3 y3 ch(x3,y3) x1 y1 ch(x1,y1) x4 y4 ch(x4,y4) ... ... ... ... where I have the value of my function at the 3 vertices of every triangle which constitutes my (triangular, not structured) mesh (see figure here What I would like to get is two separate figures: 1. something like this for the surface, with a colorbar as a legend

Passing variable values into gnuplot via data header

Let's say my gnuplot script wants to put a label or an arrow on a specific point in the data. The data have been created in another program and it could encodne them into the header line of the data file. Unfortunately gnuplot fails to use columnheader(num) to pull the data out. Example. I create histogram data including mean, sigma and some limit values. The program writing the data file puts that into the first line. Looks like this: (0.2743 is the mean and 3.0 is an outlier limit) "Data" 0

Gnuplot X value for GPVAL_DATA_Y_MAX

How can I obtain x value for GPVAL_DATA_Y_MAX? I have data generated from FLUKA simulation (proton beam hitting water phantom), which I can't describe as a function. I would like to get something like this graph from here: Gnuplot: find x value for given y but for the maximum Y value. Right now the GNUPLOT code is this: max_y = GPVAL_DATA_Y_MAX set label 2 gprintf("Maximum = %g", max_x) at 5, max_y-0.02 And the output is this: As you can see the maximum is around 3.

Gnuplot Expand array element in quotes

Gnuplot max value for same minute over multiple days from csv with unix timestamps

I have a CSV with a unix timestamp column that was collected over multiple days having a data row for every 5 minutes (output log of my photo voltaik roof power plant). I'd like to create a plot for 24 hours that shows the maximum value for every single (fifth) minute over all days. Can this be done with gnuplots own capabilities or do I have to do the processing outside gnuplot via scrips? You don't show how your exact data structure looks like, - theozh This files are rather large.

Get the current output file in gnuplot

In gnuplot you can set the output file with set output'path/to/file'. I want to write a short utility script which briefly changes the output to a different file and then resets it. Since the scripts that use the utility are generated by gnuplottex, I don't know the name of output files and therefore I can't set the output again. When you want to briefly change terminal, you can do set terminalpush before and set terminal pop after it. AFAIK there's nothing similar with set ouptut. You can sh

Stacked and grouped bar histogram with Gnuplot

I would like to reproduce a bar chart like this one, i.e.: multiple groups, every group has many bars (4 bars in my case), each bar is segmented in a few slices (two slices in my case). In my case, I have four algorithms applied on vectors of different sizes (2^0 to 2^20). Each algorithm has two "sections", local computation and communication. For each vector size I want to show the time required by each algorithm to perform the local computation and the communication, along with the total tim

Gnuplot multiaxis colormap

I have some complicated data I would like to visualize. For each point x and y in a uniform grid, there are two additional numbers, f(x,y) and g(x,y) and each goes between 0 and 1. I would like to visualize this data so that both are displayed. Since they are between 0 and 1, I was thinking of coloring with a color wheel and assign f to red and g to blue or something of that nature. I could directly make an image by converting the pixel values into an image, but the image would be 50000x100

Gnuplot symbols in epslatex terminal with dots inside

When creating symbols in combination with the epslatex terminal in Gnuplot 4.6, I always notice that in the center of the symbol a small dot is shown (clearly visible on zoom-in).
