Printing Spotfire MapChart layer information in IronPython

Basically I want to be able to print (or store) the map chart layer properties (color axis, feature by axis, etc.) from either a feature or marker layer, for all the layers in a map chart.  I'm doing something similar with bar charts, but the API for the maps is different.  Here is a snippet of the code I'm using for Bar Charts:

from Spotfire.Dxp.Application.Visuals import *

text = "Bar info:"
#loop through pages and get viz info
for p in Document.Pages:
  for v in p.Visuals:
    if str(v.TypeId) in ("TypeIdentifier:Spotfire.BarChart"):
      text += p.Title + ", " + v.Title + ", " + str(v.As[VisualContent]().XAxis.Expression) + ", " + str(v.As[VisualContent]().YAxis.Expression)
      text += ""
print text
