如何减少融合 donut2d 图表切片厚度？

Question

我正在尝试减少融合 donut2d 图表切片厚度。检查下图，我已经手动减少了绿色切片的厚度，但我想以务实的方式对所有切片进行操作。

那么有没有json减少donut2d图表切片厚度的关键？
在 Fusionchart 中可以吗？如果是，请指导我。

其实Donut的内径可以通过属性"doughnutRadius"来控制。

doughnutRadius : Number [-]
This attribute lets you explicitly set the inner radius of the chart. FusionCharts XT automatically calculates the best fit radius for the chart. This attribute is useful if you want to enforce one of your own values.

Range: In Pixels

这里有一个Sample解决你问题的方法。

如果您还有任何疑虑，请告诉我。谢谢！
