I have the following illustration in TikZ
\begin{figure}
\centering
\begin{tikzpicture}
\draw[->,thick] (-4,0)--(4 ,0) node[right]{$F_T$};
\end{tikzpicture}
\caption{asd}
\end{figure}
I would like to add ticks to the axes at the points -4, -3, -2, …, 3, 4. The only labels I want are located at -4 and 4 and should say A
at -4 and B
at 4.
Is that possible somehow in this example?
