Managing the Oracle BI Presentation Services Charting Settings

You can change certain Oracle BI Presentation Services charting settings from their internal default settings by adding entries to the Oracle BI Presentation Services configuration file (instanceconfig.xml):

• Specifying the Location of Temporary Storage for Chart Cache in Oracle BI Presentation Services
• Specifying the Interactive Behavior of Charts in Oracle BI Presentation Services
• Specifying the URL for Chart Navigation in Oracle BI Presentation Services

You need to create the elements <Chart> and </Chart> after the <ServerInstance> element, and place your entries between the <Chart> and </Chart> elements.

For information about working in the Oracle BI Presentation Services configuration file (instanceconfig.xml), read Making Oracle BI Presentation Services Configuration Changes.

Specifying the Location of Temporary Storage for Chart Cache in Oracle BI Presentation Services

You can override the internal default entry for the location used by Oracle BI Presentation Services as temporary storage for chart cache. The internal default is dirletter:\SADATADIR\Temp\nQWCharts, where dirletter is the drive where the Oracle BI Presentation Services software is installed and SADATADIR is the data directory.

The location should be a fully-qualified path name, such as d:\OracleBIChartCache. The folder or directory structure must exist before you start the service for Oracle BI Presentation Services again.

The following entry is an example:

<Charts>
   <CacheDirectory>/usr/local/OracleBI/Data/temp/chartcache</CacheDirectory>
</Charts>

Specifying the Interactive Behavior of Charts in Oracle BI Presentation Services

You can override the default interactive behavior of Oracle BI Presentation Services charts. Valid entries are Drill, Navigate and None. The default is Drill. This means that charts are created drillable by default.

If you specify Navigate, charts navigate to the URL described in Specifying the URL for Chart Navigation in Oracle BI Presentation Services. If you specify None, charts are not interactive; for example, clicking on a chart or chart region does nothing.

The following entry is an example:

<Charts>
   <DefaultInteraction>Navigate</DefaultInteraction>
</Charts>

Specifying the URL for Chart Navigation in Oracle BI Presentation Services

If you specify Navigate as the interactive behavior of charts (described in Specifying the Interactive Behavior of Charts in Oracle BI Presentation Services), you can override the default URL to which charts navigate. The internal default URL is http://www.oracle.com/.

If the interactive behavior is not Navigate, this entry is ignored.

The following entry is an example:

<Charts>
   <DefaultNavigationPath>http://www.intranet.com/</DefaultNavigationPath>
</Charts>
