Can font-size of Sunburst chart be changed ?

if could, how to set it? i had tried in 'style' but failed.

ans = sprite || me.getSurface().add({            type: 'text',
            text: text,
            font: Math.max(12, 0) + 'px Arial',
            'text-anchor': 'center',
            fill: '#fff',
            group: label
        });

i found source code where defined the font,but no param to change it. And it seems that the API Doc doesn't synchronize with the source code.
