Statement from Kunagi Team

Looks like there are no usable fonts for JFreeChart available. We need some info about operating system, application server and Java version to get deeper behind this problem.

On some distributions installing ttf-liberation or liberation-sans-fonts could help.

Status

Issue is closed.

I was seeing the same issue using kunagi 022.2 using the following:
- Fedora 15 i686
- Tomcat 7.0.22 (tomcat-7.0.22-1.fc15 from Fedora repos)
- OpenJDK 1.6.0_22 (java-1.6.0-openjdk-1:1.6.0.0-60.1.10.4.fc15)

It turns out that my headless Fedora install didn't have any fonts. By installing liberation-sans-fonts and restarting tomcat, the error went away and now I have charts.
