// .NAME vtkArcPlotter - plot data along an arbitrary polyline
// .SECTION Description
// vtkArcPlotter performs plotting of attribute data along polylines defined
// with an input vtkPolyData data object. Any type of attribute data can be
// plotted including scalars, vectors, tensors, normals, texture coordinates,
// and field data. Either one or multiple data components can be plotted.
//
// To use this class you must specify an input data set that contains one or
// more polylines, and some attribute data including which component of the
// attribute data. (By default, this class processes the first component of
// scalar data.) You will also need to set an offset radius (the distance
// of the polyline to the median line of the plot), a width for the plot
// (the distance that the minimum and maximum plot values are mapped into),
// an possibly an offset (used to offset attribute data with multiple
// components).
//
// Normally the filter automatically computes normals for generating the
// offset arc plot. However, you can specify a default normal and use that
// instead.
