Latex Bar Plot



I have the data stored on the 2024-10-26_game_count.csv file:

Engine,Steam
Godot,1691
Unity,48066
GameMaker,5032
Unreal Engine,13891
Flax Engine,0
CRYENGINE,126
Construct,302
GDevelop,57
Bevy,0
Cocos,741
Defold,31
MonoGame,387
Love2D,146
libGDX,0

We can make the bar plot using:

\documentclass{article}

\usepackage{pgfplots}
\usepackage{pgfplotstable}

\pgfplotsset{compat=newest}

\begin{document}

\begin{figure}
  \begin{tikzpicture}
      \pgfplotstableread[col sep=comma]{2024-10-26_game_count.csv}\datatable

      \begin{axis}[
      ybar,
      xticklabels from table = {\datatable}{Engine},
      xtick = data,
      xticklabel style={rotate=90},
      ]
      \addplot table[x expr=\coordindex,y=Steam] {\datatable};
    \end{axis}
  \end{tikzpicture}
  \caption{Amount of games made with the engines on Steam}
\end{figure}

\end{document}

  • We need the pgfplots and pgfplotstable packages. We must indicate the pgfplots version with \pgfplotsset{compat=newest}.

  • With \pgfplotstableread we indicate how to read the file, using commas as separation, and we define the data as \datatable.

  • To make the plot a bar plot, we use the ybar option of the axis.

  • With xticklabels from table = {\datatable}{Engine} we configure the tick labels to be the same as the first column.

  • xtick = data makes one tick for each data we have. Without this, pgfplots will reduce the number of ticks if there is much data.

  • With xticklabel style={rotate=90} we rotate the tick labels 90 degrees so they aren’t on top of each other.

  • Finally, we create the plot with \addplot table[x expr=\coordindex,y=Steam] {\datatable};. We make the point x correspond to the coordinate index and we select the point y from the second column with header “Steam”.

Here’s the result:
