Actually, I am using batik 1.6, just downloaded about three weeks ago.
In the forum, I stated that I also tried batik 1.5, but that didn't
do any changes. Do you have any other suggestions? Below is the
method that I use to save the chart as svg file.
There is a bug in 1.6 when drawing certain arcs. This may or may
not be your problem (it looks suspiciously similar). You can try
applying the attached patch and rebuilding Batik.
