Overlapping Japanese content rendered by Jfreechart in pdf

[nikel]

We are using Jfreechart along with iText for generating pdf reports. For Japanese, we realized that in the rendered content for the graph legend, characters don't have any spaces between them. They basically overlap which makes it hard to read.

is there a way to fix this?

Attached are images for expected and actual(generated by jfreechart), in that order








Below is a snippet of the graph generated with the legend
