Graphics, Figures & Tables ⇒ \ref to figure problem

[kobinissim]

Hi
When Im using the command \numberwithin{figure}{chapter}
everything is O.K, I get for example FIGURE 3.1
BUT when Im trying to use \ref to the figure I get only FIG. 3
Is anybody can help me?
Thanks

We're going to need to see a minimal working example per the Board Rules; see also the Post on Avoidable Mistakes.

Hi
Here is the code I used for the figure:

\begin{center}
\begin{figure}[h]
\begin{picture}(130,220)
\put(-125,-180){\includegraphics[scale=0.65]{PS_3d.pdf}}
\end{picture}
\put(-240,-80){\caption{Pseudospectra of Orr-Sommerfeld operator}}
\label{PS2}
\put(-30,-40){Real$\;\;\lambda$}
\put(-180,10){Imag$\;\;\lambda$}
\put(-240,140){$||(zI-A)^{-1}||_2$}
\end{figure}
\end{center}

%%%%%%%%%%%%%%%%%%%%%%%%

Now, I used The \numberwithin command and the caption of the figure was :
FIGURE 3.1. Pseudospectra of Orr-Sommerfeld operator

When I do Fig.(\ref{PS2}) The result is --> Fig.(3)
There is a problem with the \ref
If somebody know what to do with this problem
please tell me
Thanks

I strongly recommend to read the topics frabjous referred to. Do that very careful and follow the instructions unexceptionally (especially regarding the tagging of code in posts, building a minimal example, …). This is in your own interest if you expect instant help.

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

Since figure is a floating environment, it will "float" out of the center environment, so it does not make sense putting a figure environment inside a center environment.

\put(-240,-80){\caption{Pseudospectra of Orr-Sommerfeld operator}}
\label{PS2}

The \label should be on the same level as \caption, so you should write either

Code: Select all

\put(-240,-80){\caption{Pseudospectra of Orr-Sommerfeld operator}\label{PS2}}

or

Code: Select all

\put(-240,-80){\caption{Pseudospectra of Orr-Sommerfeld operator\label{PS2}}}

HTH,
