Customizing Charts

Some Oracle Billing Insight reports use Data Visualization Tools (DVT) for charts. You can customize the format of DVT charts, specifying size, fonts, color, and so on for each chart type. The properties for each report are stored in individual property files. The properties in each file apply to all report charts of that type.

You can also create additional property files with alternate formats to associate with particular reports. You can associate only one property file with a chart type at any time, however. For details about which reports can be presented as charts, see Self-Service Application Guide for Oracle Billing Insight. For details on which properties are configurable for each type of chart available, see Configurable Chart Properties.

To customize the DVT charts

1. To customize the formatting properties for a particular DVT chart, edit the property file associated with the particular chart type. The following chart property files are in EDX_HOME/config/chart directory:

   DVT Chart Type	Property File
   Vertical bar chart	vertical_bar_chart.properties
   Horizontal bar chart	horiz_bar_chart.properties
   Vertical stack bar chart	vertical_stack_bar_chart.properties
   Horizontal stack bar chart	horiz_stack_bar_chart.properties
   Pie chart	pie_chart.properties
   Line chart	line_chart.properties
2. You can create an alternate property file for a chart type and associate it with the chart type (replacing the default property file for the chart). Edit the chart section of XML in the EDX_HOME/config/rpt/filename.xml file. In the file name, filename is the name of the report. Replace the name of the properties file with the new one in the style statement as shown in the following table. Specify only one property file for each chart type at a time.

   DVT Chart Type	Chart Type as Indicated in the Report XML	Corresponding XML Style Statement Where You Specify the Chart Property File Name
   Vertical bar chart	type="BAR_VERT_CLUST"	style="config/chart/vertical_bar_chart.properties"
   Horizontal bar chart	type="BAR_HORIZ_CLUST"	style="config/chart/horiz_bar_chart.properties"
   Vertical stack bar chart	type="BAR_VERT_STACK"	style="config/chart/vertical_stack_bar_chart.properties"
   Horizontal stack bar chart	type="BAR_HORIZ_STACK"	style="config/chart/horiz_stack_bar_chart.properties"
   Pie chart	type="PIE"	style="config/chart/pie_chart.properties"
   Line chart	type="LINE"	style="config/chart/line_chart.properties"
