The information in this graph is not indicating specific information that was found for you. It is a general breakdown of the type of information the data brokers publish.
Some site publish data points like legal/court records MAY be available. This doesn't mean that they necessarily have this information, but if you pay your hard earned money to purchase a report from these sites, that information (if it exists) will be on the report.
If you read the fine print, you will often find a legal record could be anything from a bankruptcy to a traffic ticket you may have had in the past.
