1.有一個全局圖片標題居中的方法:
\usepackage[justification=centering]{caption}
2.如果排版時有的圖標題想左對齊,有的想居中,前一個方法就不好了,這里可以加上引用
\usepackage{caption}
如果還不行,在想居中的行這樣設置:
\begin{center}
\includegraphics [width=0.5\textwidth]{pic/throughput_latency_r.eps}
\caption{Latency-throughput for read workload}
\includegraphics [width=0.5\textwidth]{pic/throughput_latency_w.eps}
\caption{Latency-throughput for write workload}
\end{center}
