Hi all -
I posted a component that allows you to 'sample' a data stream. Hope this is useful to someone!

'This example generate an articial large data stream and illustrates how to use the Sample Data Stream component to reduce the size of the data stream. This component 'samples' a large data stream to reduce the number of records. This is desirable when passing it to, for example, charting components that can only deal with a limited number of records.'
