Estimated completion time: 5 minutes
In Chapter 6, "Creating a Graph for the Web Report", you added a graph to a JSP-based Web report. This chapter reviews the source code added for the graph.
Open the Web Source view for the report you created in Chapter 6, "Creating a Graph for the Web Report" called emprevb_<your initials>.jsp
.
The rw:graph
tag brackets the graph information and links the graph to the data source. It also identifies the categories and the data fields.
<rw:graph>
JSP tag.
The code within the rw:graph
tag is XML.
<rw:graph id="graph" src="G_EMPLOYEE_ID" series="EMPLOYEE_ID" dataValues="SALARY">
The series tag defines the source for the values along the X-axis, and the dataValues tag defines the source for the data along the Y-axis. You defined these parameters in the Graph Wizard in Chapter 6.
<SeriesItems>
tag below the rw:graph tag:
<SeriesItems> <Series id="0" color="#cc66cc"/> </SeriesItems>
This tag represents the modification to the Row 1 color we made in the Graph Wizard in Chapter 6. If you chose a different color, you will see a different value for the color tag.
#cc66cc
is applied to the first bar along the x-axis:
<Title>
tag, located here:
</SeriesItems> <Title visible="true" text="Employees by Salary"/>
This tag adds the graph title to your Web report, shown here:
The XML that produces the graph is closed before the </rw:graph>
JSP tag is closed.
Congratulations! You have finished reviewing the source code for your new graph. For more information on creating Web reports, adding report blocks and data, and creating graphs, see the Reports Builder online help.
