Example of Stacked Bar Chart using Remote Data

I want to map different 'Series' on 'Stacked Bar Chart' at run time utilizing remote JSON file.

My JSON file include following attribute Project ID, Year, Month and Expense. No. of projects is decided at run time.

[{"ProjectID":1,"Year":2011,"Month":11,"Expense":202.02},{"ProjectID":1,"Year":2011,"Month":12,"Expense":266.91},{"ProjectID":1,"Year":2012,"Month":1,"Expense":274.91},{"ProjectID":1,"Year":2012,"Month":2,"Expense":287.3},{"ProjectID":1,"Year":2012,"Month":3,"Expense":279.47},{"ProjectID":5,"Year":2011,"Month":11,"Expense":261.16},{"ProjectID":5,"Year":2011,"Month":12,"Expense":258.13},{"ProjectID":5,"Year":2012,"Month":1,"Expense":315.84},{"ProjectID":5,"Year":2012,"Month":2,"Expense":344.66},{"ProjectID":5,"Year":2012,"Month":3,"Expense":346.18}]

I have seen the example on the Demo Page in which 'Series' is mapped to the field names.

series:
[{
field: "nuclear",
name: "Nuclear"
}, {
field: "hydro",
name: "Hydro"
}, {
field: "wind",
name: "Wind"
}],

Is it possible to bind 'Series' by specifying fields along with values like

series:
[{
field: "ProjectID=1",
name: "My First Project"
}, {
field: "ProjectID=5",
name: "My Fifth Project"
}, {
field: "ProjectID=8",
name: "Most Eighth Project"
}],

Thanks!
