Doughnut chart becomes pie chart for single data set, any fix ?

[mukeshgla]

Hi I created a Doughnut chart using below code

Ext.define('Ext.chart.Chart', {
themeCls: 'pie1',
theme: 'Demo',
store: store1,
shadow: false,
animate: true,
insetPadding: 20,
series: [
{ type: 'pie',
donut : 70,
field: '2007',
showInLegend: true,
highlight: false,
label: {
field: 'name'
}
}
]
});

but when there is only one data set then this Doughnut becomes pie chart. Please have a look at images for more details. Can anyone let me know the solution for this ?

Is this using Touch Charts 2 beta or Sencha Touch 2.1.0?
