I have a very basic question concerning the package pgfgantt.
Take the following MWE:
\documentclass{article}
\usepackage{pgfgantt}
\begin{document}
\begin{ganttchart}[vgrid=true,hgrid=true]{1}{12}
\gantttitlelist{1,...,12}{1} \\
\ganttbar{Bla}{1}{6} \ganttnewline
\ganttmilestone{Bla 1}{6}
\end{ganttchart}
\end{document}
That is, the output should look as follows:
Month | 1 | 2 ! 3 | ...
Bla | | | | ...
Bla 1 | | | | ...
How can I get the word "Month" on the right of the number 1?
Thanks a lot for your feedbacks.
