Plotting plug-in available?

[brcain]

Hello,

What is usually done to add plotting capability to Qt? My data is stored in a database; so I'm using the MySQL plug-in. Is there something similar to Crystal Reports (that's open-source) that can be used to build queries and generate plots -- albeit leveraging Qt?

Are there user-contributed plotting plug-ins for Qt that can be added to an application?

Thanks,
Ben

There is no plugin, but there's a library - Qwt.
