  Outer Radius	The value of the radius of the pie chart area in this series of latitudes. Valid values: 0 to 1.

  Note

  The style of the pie chart area is controlled by the value of the inner and outer radii under the series. When both the inner and outer radii are set to 0 or 1, the pie chart area of this series is not displayed. When the inner radius is 0 and the outer radius is 1 or the inner radius is 1 and the outer radius is 0, the pie chart area of this series is tapered.

Parameter	Description

Table 1. Parameters

Parameter	Description
Controlled Mode	If you turn on the switch, data is not requested when a widget is initialized. Data requests are triggered only based on callback IDs or the method configured in Blueprint Editor.

     Hide/Show	The following example shows the widget. return { "animationIn": { "animationType": "", "animationDuration": 1000, "animationEasing": "linear" }, "animationOut": { "animationType": "", "animationDuration": 1000, "animationEasing": "linear" } }
     Move	Move a widget to a specified location. The following example shows the reference data. return{ // The positioning type. to indicates absolute positioning, whereas by indicates relative positioning. The default value is to. "positionType": "to", // The location, which is indicated by the x and y coordinates. "attr": { "x": 0, "y": 0 }, // The animation type. "animation": { "enable": false, // The duration in which animation is displayed. "animationDuration": 1000, // The animation curve, which can be set to linear|easeInOutQuad|easeInOutExpo. "animationEasing": "linear" } }
