# How do I add a legend to a gantt chart?

I'm using the pgfgantt package to draw a gantt chart and I am using different fill patterns for different task types (fill patterns for the task bars, that is). It works nicely! But I would like to add a legend to tell the reader which pattern stands for which kind of task.

I do believe that this is not possible from inside pgfgantt, but perhaps there are other ways of adding it?

Please add a minimal working example (MWE) that illustrates your problem. – percusse Jul 26 '12 at 13:32

I think I don't understand the question but you can add what you want inside the gantt environment. Here I added a node but you need to use current bounding box to place an object around or inside the tikzpicture.

\documentclass{article}
\usepackage{pgfgantt}

\begin{document}

\begin{figure}[ftbp]
\begin{center}

\begin{ganttchart}[y unit title=0.4cm,
y unit chart=0.5cm,
vgrid,hgrid,
title label anchor/.style={below=-1.6ex},
title left shift=.05,
title right shift=-.05,
title height=1,
bar/.style={fill=gray!50},
incomplete/.style={fill=white},
progress label text={},
bar height=0.7,
group right shift=0,
group top shift=.6,
group height=.3,
group peaks={}{}{.2}]{24}
%labels
\gantttitle{Week}{24} \\
\gantttitle{Monday}{4}
\gantttitle{Tuesday}{4}
\gantttitle{Wednesday}{4}
\gantttitle{Thursday}{4}
\gantttitle{Friday}{4}
\gantttitle{Saturday}{4} \\

%relations
\node[fill=white,draw] at ([yshift=-12pt]current bounding box.south){Box South};
\node[fill=white,draw,anchor=west] at (current bounding box.north east){Box North East};
\end{ganttchart}
\end{center}
\caption{Gantt Chart}
\end{figure}

\end{document}

EI am currently without a PC, just my phone and vy slow internet, so I can't try this out this week. But it looks good. What I already learned from this is that the gantt chart can be embedded in a \figure´ environment. I would then assume it could also be in ao tikzpicture? And then there might even be a legend package or so. I remember seeing s'th like that. In any case, I would like the legend to be inside the box of the chart, e.g. top left, above the labels. – Christoph Jul 30 '12 at 11:12
I get errors when I try to compile this. Has the package changed? – cfr Apr 16 at 21:22
I guess the syntax has changed. You need another argument for the environment and group peaks` needs to be split out, it seems. ? – cfr Apr 16 at 21:39
