From HammerDB v4.7 the ribbon effect transaction counter has been deprecated. However if preferred it can be manually enabled through the setting tc_graph_ribbon in generic.xml as shown. Note that this should be at installation as at first startup the setting will be made in the SQLite storage and subsequent changes to the xml file will not be detected. For later changes to the xml to be detected you can delete the generic.db file in the SQLite storage area and then the settings in generic.xml will be applied for future use. It is not planned to have a setting to enable/disable the ribbon effect during use and may be fully deprecated in a future release.
