You want to write two views. One that displays the graph and the form and another that generates the graph. There are several options here: 1. You have a custom content object that stores the configuration from the HTML. During image generation, you simply use the data. 2. The HTML data is simply encoded in the image source URL and is used by the image generating view: <img src=".../graph.jpg?x-axis-max=20&..." /> Regards, Stephan -- Stephan Richter CBU Physics & Chemistry (B.S.) / Tufts Physics (Ph.D. student) Web2k - Web Software Design, Development and Training _______________________________________________ Zope3-users mailing list Zope3email@example.com http://mail.zope.org/mailman/listinfo/zope3-users
