GrabLineRendererJ3D (McIDAS-V 1.9 Developer Documentation)

java.lang.Object
- visad.DataRenderer
- - visad.java3d.RendererJ3D
  - - visad.java3d.DirectManipulationRendererJ3D
    - - edu.wisc.ssec.mcidasv.data.hydra.GrabLineRendererJ3D

All Implemented Interfaces:

java.lang.Cloneable
```
public class GrabLineRendererJ3D
extends visad.java3d.DirectManipulationRendererJ3D
```
Grab and drag lines parallel to a coordinate axis. For simple 2D graphs, not yet generalized for 3D displays. For a vertical line, map Real to Display.XAxis, and assign ConstantMap for Display.YAxis. Vice-a-versa for a horizontal line.
