Text Formatting ⇒ Setting <section> as the parent counter of <figure>

[EagleLee]

Hello all

Using the original class {article}, I insert several pictures into some sections and the captions of figures are counted as Figure 1, Figure 2... normally.

I wanna get such formats as "Figure 1.1" or "Figure 1.2" in Section 1, "Figure 2.1" or "Figure 2.2" in Section 2 and so on. I use \setcounter{figure}{0} after every \section{}.

Though the ideal results are outputted, I think there must be a simpler way. I guess the counter <section> can be set as the parent counter of <figure> before \begin{document}, in which the figures inside Section X can be counted as "Figure X.1" or "Figure X.2" automatically. However, I've searched the keywords online and "texdoc-"ed the packages {hyperref} and {caption} in cmd and have little clues. Is the simpler way feasible?

I would be deeply grateful to anyone who can solve it!
