Method Detail

• getAxisName

  java.lang.String getAxisName​()

  Returns the name of the geometry type for this object. Typically this will be the name of the axis along which the independent variable runs, if there is one.

  Returns:

  function geometry name

• getXValues

  double[] getXValues​(Surface surface)

  Returns the values of the independent variable at which the function must be evaluated for a given plot surface. The drawn line will consist of a line drawn through the function evaluations at these values of the independent variable. The result should usually include some values a bit off the edge of the visible part of the surface if applicable so that the line goes right to the edge of the clipped region.

  Parameters:

  surface - plot surface on which function will be drawn

  Returns:

  array of independent variable values

• xfToData

  boolean xfToData​(Surface surface,
                   double x,
                   double f,
                   double[] dataPos)

  Converts the result of a function evaluation to a position in the data space of the plot.

  Parameters:

  surface - plotting surface

  x - independent variable

  f - dependent variable

  dataPos - nDataDim-element array to receive data position corresponding to x,f(x)

  Returns:

  true iff a valid data position resulted
