1.2
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.

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
