This extension creates a "punch card" graph of your repository similar to that offered by github. It shows the relative frequency of commits at each hour for each day of the week. Example:
It adds a new command, hg punchcard [OPTIONS].
For drawing, either PyQt4 or matplotlib can be used.
Configure your .hgrc to enable the extension by adding following lines:
[extensions] hgpunchcard = /path/to/hgpunchcard.py
