amCharts: Help with WPF MVVM Data Binding?

Looking a bit of help with Data Binding here and amCharts, through MVVM. At the minute I have:

An ObservableCollection, named AskCollection

This is a collection of SymbolObjectModels

Each Model contains a:

public double Size { get; set; }
public double BidAsk { get; set; }
public string QuoteID { get; set; }

Currently I'm attempting to bind the data in the XAML as follows, with no luck:

<xaml>
    <am:LineChart Grid.ColumnSpan="2" SeriesSource="{Binding AskCollection}" IDMemberPath="{Binding QuoteID}" Background="DimGray">
                <am:LineChart.Graphs>
                    <am:LineChartGraph DataItemsSource="{Binding AskCollection}" ValueMemberPath="{Binding BidAsk}" SeriesIDMemberPath="{Binding QuoteID}">
                    </am:LineChartGraph>
                </am:LineChart.Graphs>
    </am:LineChart>
</xaml>

Unfortunately, there is no Line Chart appearing :( I also tried with a List opposed to an ObservableCollection, still no joy.

Can anyone see what I'm doing wrong?

Much appreciated, Cheers.

IDMemberPath, ValueMemberPath, etc. are supposed to be property names, not bindings. Ie. IDMemberPath="QuoteID", etc.
