getSizeField

SummaryField getSizeField()

Returns the data field which provides the size of the bubble. This property is for chart style XYStyle.BUBBLE only.

setSizeField

void setSizeField(int summaryOperation,
 Field field,
 Field field2nd,
 int nth)

Sets the data field which provides the size of the bubble. This property is for chart style XYStyle.BUBBLE only. Creates a new SummaryField with this field, operation and parameters.
For more information on the supported value types of fields and on using parameters 'field2nd' and 'nth' see SummaryField.

Parameter:

summaryOperation - the summary operation. This only supports operations with number results

field - the data field

field2nd - the second data field, used for example for weights in weighted average SummaryField.WEIGHTED_AVERAGE.

nth - the nth parameter, used e.g. by summary operation SummaryField.NTH_LARGEST

Löst aus:

IllegalArgumentException - if the first or second field are required and null or have an unsupported value type.

IllegalArgumentException - if nth is less than zero.
