How to set Font to Subtitle in pichart using jfreechart?

I have generated piechart which has subtitles i.e. Cash ,total,Security now problem is that subtitles are appearing bigger than actual piechart.

enter image description here

How can I set font to those subtitles ?

Solution

For Labels

StandardPieSectionLabelGenerator slbl = new StandardPieSectionLabelGenerator("{0} [{1}]",new DecimalFormat("#,##0"),new DecimalFormat("0%"));
piePlot.setLabelGenerator(slbl);

For the font

new Font("SansSerif", Font.ITALIC, 7)

I suggest you try to add that Font into the StandardPieSectionLabelGenerator
