Field Detail

type

protected int type

Type of data change. One of the enum values specified in this class.

seriesIndex

protected int seriesIndex

Data series impacted by change (if applicable).

pointIndex

protected int pointIndex

Point index impacted by change (if applicable).

RELOAD_POINT

public static final int RELOAD_POINT

Enum value indicating a single data value has changed. In this case, seriesIndex and pointIndex are used to index the point. An event of this type should be used when a value has been changed in a series value array that has previously been queried by the chart from the data source. If the array needs to be regenerated, RELOAD_SERIES should be used instead.

Constant Field Values

RELOAD_SERIES

public static final int RELOAD_SERIES

Enum value indicating a data series has changed. In this case, seriesIndex points to the series to reload. An event of this type will requery the series value array from the data source.

Constant Field Values

ADD_SERIES

public static final int ADD_SERIES

Enum value indicating a data series has been added to the end of the set of data series.

Constant Field Values

INSERT_SERIES

public static final int INSERT_SERIES

Enum value indicating a data series has ben inserted at a particular index in the set of data series. In this case, seriesIndex holds the index at which to insert the series.

Constant Field Values

REMOVE_SERIES

public static final int REMOVE_SERIES

Enum value indicating a data series has been removed. In this case, seriesIndex holds the index of the series to be removed.
