    public interface TupleSequence
    extends Tuple
    Interface for iterating over points to plot. At each step, a tuple of values required for the plot is available. Elements of the tuple are addressed by index, i.e. column. Each step represents a point which is a candidate for plotting; some rows of the original data set may be excluded if that data set has been subsetted to produce this sequence.

    This interface extends the Tuple interface. Objects implementing this interface allow access to each of their fields at the current row only.
