For example, do not state “Popularity as a function of president height” instead, state “Taller presidents are more popular”.įinally, a note on color. If possible, start your figure heading by stating what the figure is meant to demonstrate (i.e., its interpretation). However, we will say that it is clearly desirable to have the main message of a figure be understood without being forced to read the main text. This compendium does not discuss figure headings. In our experience, many graphs can be dramatically improved by adhering to the following guidlines: (1) invest sufficient time and effort in the process (2) omit needless graphical elements, that is, make every element count (3) judge the relative impact of the graphical elements and ensure that they are in balance (4) use large font sizes for all text (5) deviate from the R default settings – with a little effort, you can do a lot better.

Hopefully this will make it easy to copy-paste and adjust the code to suit your own needs. This is the phase where this compendium may be useful, because it brings together R code for producing a set of clean, publication-ready figures.

Second, you have to use computer software to translate the conceptual graph to a publication-ready figure. First you have to consider what is the best way in which to convey the information: a line graph, a histogram, a multi-panel plot such conceptual dilemma’s are not dealt with in this compendium, and instead we recommend the reader to the chapters on creating graphs in the excellent book by Briscoe (1996). Producing clean graphs can be a challenging task. This work has profited greatly from interactions with our colleagues, many of whom have contributed graphs of their own. For an example, see Figure 1 from this paper. The advice: when you create a clean graph in R, put it on Flickr (public license) before you sign away your copyright to a publisher. The request: if you create a clean graph in R that you believe is a candidate for inclusion in this compendium, please do not hesitate to contact us at or Your contribution will be acknowledged explicitly, alongside the code you provided. We close with a request and a piece of advice. A note for R fans: the majority of our plots have been created in base R, but you will encounter some examples in ggplot.Īlmost every example in this compendium is driven by the same philosophy: A good graph is a simple graph, in the Einsteinian sense that a graph should be made as simple as possible, but not simpler. The graphs can all be reproduced and adjusted by copy-pasting code into the R console. This compendium facilitates the creation of good graphs by presenting a set of concrete examples, ranging from the trivial to the advanced. Consequently, the produced graph is often a severe distortion of the ideal Platonian graph that the researcher had in mind initially. We surmise that this is because researchers do not completely master their graphing software, and they are either too lazy or too busy to remedy the situation. Unfortunately, researchers generally suck at making good graphs. When done right, graphs can be appealing, informative, and of considerable value to an academic article.
