     Will graph count of changed lines or revisions grouped by template
     or alternatively by date, if dateformat is used. In this case it
     will override template.
 
     By default statistics are counted for number of changed lines.
 
     Examples:
 
       # display count of changed lines for every committer
       hg churn -t '{author|email}'
 
       # display daily activity graph
       hg churn -f '%H' -s -c
 
       # display activity of developers by month
       hg churn -f '%Y-%m' -s -c
 
       # display count of lines changed in every year
       hg churn -f '%Y' -s
