Dear elazutkin,

Please find the attachement for Donut chart,

The code is copy paste of Pie chart , and been modified where the slice drawing logic is written.

Hope this code is of required standards for dojox distribution.

Sorry this took so long, I will review and hopefully land for Dojo 1.12.

Hello,

Just like Digambar Sangavkar, we were interested in a Donut plot. We started by superposing 2 Pies. But finally we extended dojox/Pie and overrode render() in order that the background color can be visible at the center and real arc shapes replaced the circle shape.

Other things we implemented : inner disk text, inner disk event support.

Because our render() method is an adapted copy-paste of the big render() method. We are still interested in a dojox/Donut.

Thanks
