Chart rendering

[Greg]

I'm a bit stumped as to what I may have missed in my code. I know that data is being returned from the web service, there are no errors setting the dataSource and the dataBound event fires, and yet I see no columns on the chart. If I hard code series data then it renders OK. Can anyone spot anything that's incorrect?

This is the Json data being returned ...

{
    "d": [
        {
            "location": " Garden (AUS)",
            "amount": "4661"
        },
        {
            "location": "Suites ",
            "amount": "1768"
        },
        {
            "location": "Marriot",
            "amount": "2292"
        },
        {
            "location": "Santa Rosa",
            "amount": "1616"
        },
        {
            "location": "W",
            "amount": "275"
        }
    ]
}
