>I am looking for recommendations for a good component that I can use in both a webservice and a desktop app that creates graph graphics on the fly, probably in JPG format. These graphics will be integrated into documents, which the web service or desktop app will return. I do not need any web or winform control functionality to display the graphs in a control.

>The data that these graphs illustrate will be calculated on the fly, not by doing database queries.
>
>I need control over the resolution, dimensions, format, and appearance of the graph graphics.
>
>I would prefer a flat fee license that is per developer or per station, not per webserver or per desktop installation.

>Thanks for any suggestions.
