This article is a tutorial on plotting graphs with LaTeX. It contains a number of examples that will be of immense use to readers who wish to try it out. It also has a comprehensive list of references, which will be of further use.
The LaTeX package for plotting is pgfplot. In other words, pgfplots is a package that plots by coding. Further on in this article, an example of a flowchart will be shown. All the examples presented here are as standalone plots and are made with ProTeXt 3. Data management The first important thing to be aware of is how to use the data.
For a short table, I use the coordinates of each point, as shown in the following code:. This data has been taken from Reference 1 given at the end of the article. Another way to use a short table is to use tableas shown in the following example:. This meteorological data has been published in References 2 and 3.
If the table is a bit longer, I can continue to use pgfplotstablereadbut in another way, as shown below:. Probably, the simplest way is to put the data file, for example pressure. File structure A generic LaTeX file has the following well-known structure:. The following example is a bit more detailed:.
In this part, addplot is also present. Each data series has its own style options as specified with p1 and p2. The file pressure. It has the following structure:.

In the axis section, the following options are used:. The option closedcycle defines a closed surface for each series. This is the main difference between an area plot and a bar plot. The same table could also be plotted as a bar plot. The axis section contains, among the other options, the following code.When starting my research in causality, I did not know how to draw causal models.
Most people I asked drew their graphs in powerpoint or some other software, and then exported them as png. Drawing the graphs from scratch was tedious, and they often ended up looking fairly amateurish. To combat this, a couple years ago, I created a web-based app to draw graphs and export them to png, which is available here. The exported pngs were easy to make, but there was the issue of needing to align nodes each time I needed to make a change, and the resulting graphs were passable, but did not look beautiful.
Since then, members of our group and I have figured out how to make these graphs directly in latex, and I think they look really great. Here is a full template document with a tikz graph.
The majority of the above code can be simply copy-pasted into your own tex file without modification. The only thing that you need to change for your own graphs is within the tikzpicture. You might have noticed that the output of the given code is a pdf, while the graph shown above is an svg.
The actual code used for the above graph is given hereand the image can be generated on linux using:. All the below graphs assume to have the same tikz settings as shown in the template above, with just the tikzpicture portion replaced. This post serves as an example-based intro to causal graphs in tikz.
The Basics Here is a full template document with a tikz graph.The pgfplots package is a powerful tool, based on tikzdedicated to create scientific graphs.
Pgfplots is a visualization tool to make simpler the inclusion of plots in your documents. Since pgfplot is based on tikz the plot must be inside a tikzpicture environment. Inside the squared brackets some options can be passed, in this case we set the colour of the plot to red ; the squared brackets are mandatory, if no options are passed leave a blank space between them.
Inside the curly brackets you put the function to plot. Is important to remember that this command must end with a semicolon. To put a second plot next to the first one declare a new tikzpicture environment. Do not insert a new line, but a small blank gap, in this case hskip 10pt will insert a 10pt-wide blank space. This will add a 3dplot, and the option surf inside squared brackets declares that it's a surface plot.
The function to plot must be placed inside curly brackets. Again, don't forget to put a semicolon ; at the end of the command. This way the code is more readable and is easier to add further options if needed. Open an example of the pgfplots package in Overleaf. To include pgfplots in your document is very easy, add the next line to your preamble and that's it:. Some additional tweaking for this package can be made in the preamble. To change the size of each plot and also guarantee backwards compatibility recommended add the next line:.
This changes the size of each pgfplot figure to 10 centimeters, which is huge; you may use different units pt, mm, in. The compat parameter is for the code to work on the package version 1. Since L a T e X was not initially conceived with plotting capabilities in mind, when there are several pgfplot figures in your document or they are very complex, it takes a considerable amount of time to render them.
To improve the compiling time you can configure the package to export the figures to separate PDF files and then import them into the document, add the code shown below to the preamble:. See this help article for further details on how to set up tikz-externalization in your Overleaf project.
Pgfplots 2D plotting functionalities are vast, you can personalize your plots to look exactly what you want. Nevertheless, the default options usually give very good result, so all you have to do is feed the data and L a T e X will do the rest:. Scientific research often yields data that has to be analysed. The next example shows how to plot data with pgfplots :.
Scatter plots are used to represent information by using some kind of marks, these are common, for example, when computing statistical regression. Lets start with some data, the sample below is to show the structure of the data file we are going to plot see the end of this section for a link to the L a T e X source and the data file :.
I was looking for it here in Stack Overflow as in Google, and I found a lot of packages to draw, but it seems a complex task, so I would like to know which is the most appropriate package to draw bars, and associate data to it. Also I was looking for a code example, but I did not have luck. That sounds like an easy job for the pgfplots package. Section 4. If you need more pgfplots examples, the section dedicated to plots at TeXample could be of interest.
There aren't any bar plots, but it contains some nice and more elaborate examples of the functionality. As for a code example, I could copy-and-paste one from the manual, but that would not add much to this post I believe.
Edit: when using Matlab, it is possible to use matlab2tikz. This way you can export your plots without having to worry about the actual code. Bar charts should be possible, but I haven't used that functionality yet so I don't know about any quirks. The plots I did export using this Matlab script were perfect and you get the consistency and flexibility you want :. I plan to add some more examples to my GitHub repository.

Martin Thoma Martin Thoma I tried both options. This sample codes compile but when I produce a PDF I see a blank page with a few digits on it - no bar chart. Shouldn't dvipdfm be able to parse the compiled dvi file from these two samples?The basic steps are. Instead, we illustrate the process with a simple plot of sin x.
Note that if you have multiple figure windows open, the "print" command is applied to the top-most plot. There is more than one way to do it. Here is a short LaTeX source file that shows how it is done. The plot appears centered on the page and scaled at 60 percent of its original size. Because the plot is stored as EPS, there is no loss in quality. If the plot is scaled too drastically the axis font and plot symbols may become hard to read. LaTeX floats are automatically placed at the top or bottom of nearby pages.
Finer control over float placement is possible, but will not be described here. While we're at it, let's define the caption and a tag for the figure. The caption will appear below the plot and will automatically be numbered.
If you have a document with many figures, it is sometimes an advantage to store them in a subdirectory of the directory that holds the. Suppose then that the EPS files are stored in the "eps" subdirectory.
Multiple graphics diirectories can be specified. Insert the plot into your LaTeX document There is more than one way to do it. Insert the plot into LaTeX floating figure LaTeX floats are automatically placed at the top or bottom of nearby pages.

I am using Kile in Ubuntu. I exactly don't know that which package should I use. Any suggestion with example is highly expected. I think the best approach is to use the tkz-berge from Altermundus. You can also find a complete guide here.
It is an example of a Markov Chain in which several TikZ options are used. In the same guide, you will find an example in which nodes are placed in a matrix. You can use the tkz-berge package. This package uses TikZ it's possible to add all the commands of TikZ. I wrote a document with some classic named graphs. Here an example to draw the Petersen's graph only with TikZ I try to structure correctly the code. The first scope is used for vertices ans the second one for edges.
As there lacks an answer with pstricks, here a very simple code for the Petersen graph; it uses pst-poly :. In case you do not want to do the layout yourself, you can use Graphviz to do so. That will result in a ". I just used my GraphvizFiddle tool to get "circo" layout for Petersen graph and verified that dot2tex works. Here is share link for the Petersen graph, switch output from "svg" to "dot" and press "Draw" button to get the Petersen ".
The tex output uses "tikzpicture" as well. Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered. How to draw graphs in LaTeX? Ask Question. Asked 7 years, 10 months ago.

Veuszyou can also easily convert the svg output into an editable LaTeX graph, as there's an extension for Inkscape to save as tikz. Yetish Joshi wrote a guest post on our blog explaining the steps to do this -- if this is what you were thinking with your question then you can find more info here. Hope this helps this didn't feel like a full answer so I posted it as a comment.Suppose that we want to insert a graph of the sine function in a LaTeX document.
That is, we would like to have the following result: Because the support for creating graphs in LaTeX itself is limited, it is best to rely on an external graphing program. That is, you create the graph of the sine function with the graphing program and save the result to a file. Then you include that file as a figure into your LaTeX document. The best file formats for saving graphs are the vector graphics file formats EPS and PDF because these are well supported by LaTeX and because they can be scaled without loss of quality to any resolution.
Any graphing program that supports these file formats can be used to create graphs that can be included in a LaTeX document. Further down this page, I will show how the free software graphing tool GLE can be used to this end. If you want to follow this example, you can download such a file for the sine function here: sin. The following is an example of a LaTeX file that includes the figure from the file "sin.
Note that the extension ". If you process your document with "latex" into DVI format, then it will use the ". Below I'll assume that you use "pdflatex". Assume you have saved the above LaTeX document to a file called "graph.
Now you can run " pdflatex graph.
