Consume temperature data and display in RadChart

[Han]

Hi,

I'd like to accomplish the following:
1. Consume temperature data from a reliable source (using web service or whatever method is better?)
2. Display the data in RadChart
I'm new at this so I don't know what's the best way to do this. Any website/tutorial/samples from you would be greatly appreciated.

Thanks,
Han

Hi Zhe,

Generally, almost any example can be considered plotting a temperature. This particular one shows RadChart in a scenario involving temperatures. In addition, you may check this example for details about plotting data against DateTime values. I would also suggest checking our online help  for RadChart.

Kind regards,

Hi,
Thank you for your suggestions. However, the temperature example you referred to is not what I was looking for. In the example the temperature data were generated by the Random function. I was looking for real, historical temperature data. Do you have any suggestion for that?

What I find the easiest to do is to get the data from a query and fill a DataTable with it. From there you can either manually add series to your chart, or just let the databinding do its work. If you follow the suggestions and guidelines in the demos which Ves provided with your historical database it should be able to be applied, just taking the place of the Random data.

Hi Han,

You can either use Carl's solution, or create a chart series and fill the newly coming data points in.

All the best,

Sorry about the confusion. Let me clarify. I want to know where to get historical temperature data and what's the best way to consume it? (ie. Google, Yahoo, Weather.com, etc)?

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.
