Specified by:

addPen in interface IPenDatasource

getHistogram

public IHistogram getHistogram()

Specified by:

getHistogram in interface IHistogramDatasource

registerQuery

protected Object registerQuery(int pollTime,
 boolean runOnce)

Description copied from class: AbstractChartQuery

Register this query with the QueryManager. Called by AbstractchartQuery during AbstractChartQuery.startup(PMIEasyChart)

Specified by:

registerQuery in class AbstractChartQuery

Returns:

The key object that the query manager gave back.

setData

protected void setData(Dataset data)

Overrides:

setData in class AbstractChartQuery

initRefs

Description copied from interface: IPenDatasource

The underlying dataset that drives this datasource

Specified by:

getDataset in interface IPenDatasource

isZoomTracking

public boolean isZoomTracking()

Description copied from interface: IPenDatasource

True if this datasource should be restarted when the zoom level changes.

Specified by:
