DVribbons_plot creates height surfaces of a 2D field by treating the values of a
component of that field as height above the surface of the field, and the values of
another component as color to be applied. The surfaces so created are continuous
along one axis (selectable as X or Y) and discontinuous along the other axis, so
they look like a set of colored ribbons draping over a surface.
Mesh_Unif+Node_Data. The ribbon plot is built on this mesh, using the node data values as heights.
int. Selects which direction (X or Y) the ribbons should run in.
int. Which node data component to map to ribbon height.
int. Which node data component to map to ribbon color.
float. This scale factor is applied to the data values to convert them into heights above the mesh.
float. This offset is added to the heights to offset the ribbons from the surface of the field.
Mesh+Node_Data. Contains the generated ribbons.
