I can't be sure, but I believe it's a compatibility issue of iReport v3.5.3. I think so because iReport v3.5.3 is a fresh release and it's not supported by other Jasper products yet (like JasperServer). To be more precise, the latest release of JasperServer has the same chart problem with iReport v3.5.3
I'd suggest using iReport v3.5.0 or v3.5.1
