One of our customers reported the attached problem. We are not able to reproduce locally, but it seems related to the time duration set. For small durations (less than 1 week), the data shows fine, for longer graphs (one week), the data becomes jumbled.
We have many deployments and it is the first time we see this behavior. We tried to upgrade to the latest version of jfreechart without success. Customer is running Java 1.6.0_24 on Windows XP (so do we).
Do you have any idea of what we need to look, to either reproduce or solve the problem? We did not upgrade any other JAR. What are the libraries (both Windows and JARs) that we should check.
Thank you for the help.
