Hi Xinman,
I'm in the UK and can only answer briefly. Study these
Sections of the VisAD Developers Guide:
3.1.14 Application Example: Synthesizing MathTypes
3.2.14 Application Example: Synthesizing Fields
and also visad/examples/Test03.java.
You need to Construct a FunctionType:
(RealType.Time -> temperature)
and use DateTime to help construct a Linear1DSet for your
dates/times (which appear to be evenly spaced - if they
weren't you'd construct a Gridded1DDoubleSet instead of
the Linear1DSet).
Then construct a FlatField from these, and call setSamples()
to put your temperature values in it.
Then construct a DisplayImplJ3D (or DisplayImplJ2D), link
it to your FlatField (as in Test03.java or any other
example), and construct ScalarMaps:
ScalarMap(RealType.Time, Display.XAxis)
ScalarMap(temperature, Display.YAxis)
and addMap() these to the DisplayImplJ*D. Study the guide
and the examples, and hopefully it will become clear.
Cheers,
Bill
