I'm not sure if "transpose" is the right term.
I'm trying to go from this
Date        A     B     C
1/1/2000    1.25  1.0   .75
1/8/2000    .5    1.5   1.0
1/15/2000   1.0   .75   1.25
to this
Date        Site  Value
1/1/2000    A     1.25
1/8/2000    A     .5
1/15/2000   A     1.0
1/1/2000    B     1.0
1/8/2000    B     1.5
1/15/2000   B     .75
1/1/2000    C     .75
1/8/2000    C     1.0
1/15/2000   C     1.25
using Pandas.
Any ideas?
