Class CurveData

java.lang.Object
  ifi.dsb.CurveData

public class CurveData

extends java.lang.Object

Class to hold data coordinates for a curve, along one axis. The coordinate values are copied to an internal storage buffer.

Implementation note: The double-precision floating point data values are scaled and converted into an integer-valued array of the same length. The integer values are pixel coordinates.

Constructor Detail

CurveData

public CurveData(Plot2D plot,
                 Curve curve,
                 double[] data,
                 int orientation)

Construct CurveData object. Update axis minimum/maximum unless they have been set to be fixed.

Parameters:

plot - Plot where the curve-data will appear.

curve - The curve this data belongs to.

data - Curve coordinate values along the axis. The array is copied to an internal storage buffer.

orientation - Axis.VERTICAL or Axis.HORIZONTAL to tell which axis the data are for.

CurveData

public CurveData(Axis axis,
                 Curve curve,
                 double[] data)

Constructs CurveData object. Update axis minimum/maximum unless they have been set to be fixed.

Parameters:

axis - Axis which this data belongs to.

curve - The curve this data belongs to.

data - Curve coordinate values along the axis. The array is copied to an internal storage buffer.

CurveData

public CurveData(Axis axis,
                 Curve curve,
                 double[] data,
                 int n)

Constructs CurveData object. Update axis minimum/maximum unless they have been set to be fixed.

Parameters:

axis - Axis for this data.

curve - The curve this data belongs to.

data - Curve coordinate values along the axis. The array is copied to an internal storage buffer.

n - Number of data samples to copy (starting with the first).
