Re: Display a series of 2D curves in a 3D display

Hi Mark,

Put your data in a FlatField with MathType:

  ((x, y) -> (z, errorlow, errorhi))

Then make ScalarMaps: x-> XAxis, y -> YAxis, z -> ZAxis,
errorlow -> Shape, errorhi -> Shape. Pass VisADLineArray[]
arrays to the setShapes() methods of the two ShapeControls
for appropriate top and bottom error bar half-shapes,
along with appropriate Linear1DSets to their setShapeSet()
methods (assume errorlow and errorhi values are 0.0 for no
errors, that is relative to z values). Note Test47.java in
visad/examples will give you an example of using Shape.

Good luck,
Bill
