I am not sure what you might have to use to snag this kind of data from websites. I do know that many sites get their weather information from Weather.com
, but I am unsure about the API for which to gather this data. Weather Underground
is another site which you can use, but again I'm not sure how you can grab that data.
As for the consumption I believe the best alternative would still be to manage a DataSet object which you can take tables from and apply them as the datasource of the RadChart.
