This property specifies the Flash variables. The object values can be any of the following:

• SwfActionValue.Undefined – the undefined value.
• SwfActionValue.Null – the null value.
• A Boolean – a primitive Boolean.
• A Char – a primitive string consisting of one character.
• A SByte, Byte, Int16, UInt16, or Int32 – a primitive number (32-bit integer).
• A UInt32, Int64, or UInt64 – a primitive number (32-bit integer if it is within the range of 32-bit integer; double-precision floating-point number, otherwise).
• A Single – a primitive number (single-precision floating-point number).
• A Double – a primitive number (double-precision floating-point number).
• A Decimal – a primitive number (32-bit integer if it is an integer within the range of 32-bit integer; double-precision floating-point number, otherwise).
• A String – a primitive string.
• IEnumerable<KeyValuePair<string, object>> – an object with KeyValuePair<string, object>.Key as the property names and KeyValuePair<string, object>.Value after this conversion as the property values.
• IEnumerable<object> – an array with the objects after this conversion as the element values.

Reference semantics of objects is supported. When the same IEnumerable<KeyValuePair<string, object>> or the same IEnumerable<object> is in different parts of this property value, the same object is used. In particular, you can create objects and properties/element values that form circular references.

Here, we import the chart in the frame at two seconds into a Flash movie.
