未定义对图的引用

未定义对图的引用

我正在撰写一篇研究论文,试图解决的问题与引用图表有关。编辑器中的警告显示:

Reference fig:fig5 on page 2 undefined input
Now enter a title, Key Term 1, Description for Key Term 1, Key Term 2, and Description for Key Term 2. You can click the Add More button to create more entries for key terms and their descriptions. For example, to create the word matching exercise in Figure \ref{fig:fig5}, you can enter the following entries in Figure \ref{fig:fig5}.

Now click the Generate HTML button to display the generated HTML code for this word matching exercise. The HTML code is generated as shown in Figure \ref{fig:fig6}. Click the Post button to post the word match exercise to the server. 

\begin{figure}
  \includegraphics[scale=0.4, clip,width=0.9\linewidth]{figure/fig_4.PNG}
  \label{fig:fig5}
\end{figure}

该图标记如下:

\label{fig:fig5}

任何能帮助解决这个问题的帮助都将不胜感激。谢谢。
