Just wanted to check if there is any configuration or parameter to get statistics in a provided date range rather than it's giving stats from DAY1?
Since StatSVN is running on locale log files, it's totally possible:
Check out a working copy of your project from Subversion.
svn co svn://server/repo/trunk/modulename
Create a Subversion log file, specifying the date range you want:
svn log -v -r {2012-05-01}:{2012-05-31} --xml > logfile.log
Run StatSVN:
java -jar /path/to/statsvn.jar /path/to/module/logfile.log /path/to/module
This command creates the HTML reports in the current directory.
More details are available from the User Manual.
