## org.das2.qds.CdfSparseDataSet

dataset for modeling when data values repeat. Instead of storing copies of the data, the get method looks up the index. For example:

     ds= CdfSparseDataSet(1,200,dataset(1))
     ds.putValues( 10, dataset(2) )
     ds.putValues( 110, dataset(3) )
     plot( ds )

## CdfSparseDataSet( int rank, int length, QDataSet value )

create the DataSet with the given length.

## datasetCount

datasetCount( ) → int

return the number of different datasets.

### Returns:

the number of different datasets.
