I'm fairly new to using LaTeX, so don't blame me for asking obvious questions. The ganttchart in the code below will be placed above the section title, and I have no clue why. Any help would be appreciated.
\section{Tables}
\begin{figure}[ftbp]
\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},

progress label text={},

group top shift=.6,

group peaks={}{}{.2}]{20}
