The dashboard style file _default_dashboard_styles.xml contains a list of type-specific style templates (styletemplate XML elements) that determine the appearance of process groups, processes, and measure queries in your Performance Dashboard user interface. The style templates specified in this file can be assigned to particular interface items in Dashboard Builder.
Specific display properties can be defined independently for each dashboard by creating a _styles.xml file with the same base name as your dashboard definition file.
Procedure
The default configuration file _default_dashboard_styles.xml is located in the templates\config\default\performancedashboards subdirectory of your Performance Dashboard installation directory.
If you do not want to use dashboard-specific style templates and the dashboard style file <dashboard name>_styles.xml does not exist in the client directory webapp\WEB-INF\config\<client name>\performancedashboards on your Web application server, the default style templates from the file _default_dashboard_styles.xml in the client directory will be used. If this file does not exist, either, the file _default_dashboard_styles.xml in the directory <PPM installation directory>\server\bin\agentLocalRepo\.unpacked\ppm-web-run-prod-<version>-runnable.zip\ppm\PerformanceDashboard\templates\config\default\performancedashboards is used.
