I define the MyChapter as a newcounter for my chapters. I use the

\renewcommand{\thefigure}{\theMyChapter.\arabic{figure}}

for figure numbering. I works correctly up to chapter 3, but from chapter 4 it does not reset the figure numbers. For example if I have 3 figure in chapter 3, the first figure of chapter 4 is number 4.4 and the second one is numbered 4.5 (it means it does not reset). What should I do?

Edited: The document seems like this:

    Try \numberwithin{figure}{chapter} – user121799 Aug 4 '18 at 14:58

    With an uptodate TeX Distribution you can use \counterwithin{figure}{chapter} without an additional package. With older distributions you have to load package chngcntr. Macro \numberwithin is provided by package amsmath. – esdd Aug 4 '18 at 15:08

    To answer this, we would need a complete but minimal document, starting with \documentclass and ending with \end{document}. How would @esdd know you're loading amsmath? – user121799 Aug 4 '18 at 15:50

    Also we do not know how the counter Mychapter is defined and what the purpose of its definition is. It could also be that you want to use \numberwithin{figure}{MyChapter} ... – esdd Aug 4 '18 at 16:03

    I'm voting to close this question as off-topic because it is solved in comments. – Mensch Apr 4 at 5:40
