Method Detail

applyBoundary

public XYGraphData applyBoundary(Range xboundary,
                                 Range yboundary)

Description copied from interface: GraphData

Apply the new boundary on x/y direction. Data outside the boundary are ignored.

Specified by:

applyBoundary in interface GraphData

Parameters:

xboundary - the new boundary to apply

yboundary - the new boundary to apply

Returns:

a new GraphData instance

addPoints

public XYGraphData addPoints(ArrayPair xy)

Returns a new LineData that contains the appended points.

Parameters:

xy -

Returns:

a new LineData object.

getXy

public ArrayPair getXy()

getX
