Oracle had this excellent graph utility in the earlier releases of Jdeveloper. It was Bi-graph, which user can use to represent the data in graphical forms.

This has been replaced in JDeveloper 11g by DVT component. However, the new Faces DVT component forces user to use Faces components, which may not be a requirement always. Neverthless, both the components (old BI graph and latest DVT components) are closely tied to the Datacontrols. What if user has Hibernate at the server side and want to use these components. The writeup, descibes one of the different ways, to show the data using BI Graph.

The IDE used was Oracle Jdeveloper

Idea is to create an oracle.dss.thin.beans.graph.ThinGraph object in the background, set the data from any datasource (dummy data in this example), export the graph as image, and show in the JSP

Idea creates a Graph object. The visual properties required by Graph will be provided by an xml file. Jdeveloper provides a wizard to edit the xml. This however can be edited without Jdeveloper, if user is aware of the elements required:

        } catch (Exception e) {

The example also shows how to change the graph at runtime

One running the JSP, user should be able to see the desired graph as shown below:

The jars used in the application came with Oracle BI beans, 1012, which can be dowbloaded from
The jars used were:
jewt.jar (it came from Jdev)

PS: With the new DVT components, user may need to use instead of ThinGraph and may have to set all the properties directly to the UIGraph instance instead of using the xml.
