#2 Exception when creating stats

Milestone: 1.1

Running svnstat for a project fails with the following exception:

debug@vc242 /tmp/svn $ java -classpath ./SvnStat-all.jar de.agentlab.svnstat.SvnStat -jar ./SvnStat-all.jar -r repo.log -d stats
org.jCharts.properties.PropertyException: The Axis Increment can not be a negative value or zero.
at org.jCharts.properties.DataAxisProperties.setUserDefinedScale(Unknown Source)
at de.agentlab.svnstat.Graph.lineChart(Graph.java:122)
at de.agentlab.svnstat.Stat.fileCount(Stat.java:433)
at de.agentlab.svnstat.SvnStat.run(SvnStat.java:93)
at de.agentlab.svnstat.SvnStat.main(SvnStat.java:257)

This only happens for one project - the other projects work just fine.

I encountered this error too - when there were no commits to analyze (in a given date range). I was able to reproduce issue, have a fix for it, and will contact @lind to ask whether I can join the project to contribute the fix.

I plan a fix for this issue in the 1.1 release. Thanks to @lind for letting me join the project to help.

Note that besides the error in question producing the output described (i.e. org.jCharts.properties.PropertyException: The Axis Increment can not be a negative value or zero.), it also causes no File_Count.jpg being generated for the analysis (resulting in a broken image in the HTML report).

It turns out that the fix noted on 2014-09-01 left an edge case where the issue could still arise - when the difference between the min and max file counts is less than 4 - for example:

The repo being analyzed begins the time period being analyzed with 273 files.

The repo being analyzed ends the time period being analyzed with 276 files.

The repo being analyzed never has less than 273 files or more than 276 files during the time period being analzyed.

The difference between the min (273) and max (276) files in the repo during the time period being analyzed is therefore 3 (i.e. less than 4).

I have committed a fix for this edge case in SVN revision 13 that is pending the 1.1. release.

Thanks for the update, Joe. I just did a small verification on 1.1 beta and looks like a new issue arised. Could this be any of the missing jre updates or missing updated pre-requisites at my end ?

Hi Joe and all,
Was able to figured out the cause with the unsupported class version error I reported in my previous message related to 1.1 beta release. A little googling and debugging helped it resolve.

Cause:
1.1 beta no more works with JRE 1.4
Fix that I tried which worked out:
used latest available JRE 1.8 (http://www.oracle.com/technetwork/java/javase/downloads/server-jre8-downloads-2133154.html)

Thanks for the code, Joe,

VC
