Q1:In oceanography it's customary to have a "reversed" axis for depth.
For example, a 2D plot of some measured value (like salinity) ert to
depth, the origin of the Y axis is at the top of the axis and
represents the surface of the ocean. Depth increases down the axis
rather than up from the cartesian origin. Is there any way to tell
VisAD to draw a reversed axis?
Q2: I have succeeded in producing 3D scatter plots where the plot
symbol is colored by another measured variable. Is there a way in VisAD
to connect the plotted points with a line segment? If so, can the line
segment also be colored by the color variable?
