Hi Ben,
Your query seems to be based on a different input ("GRCMAPLE-1" is not
included in the example XML document), and…> CREATE DB bullion-2 /home/bpracht/java/basex-10.4/ …by running this command, you are creating a database with all XML documents found in the given filesystem path (that’s why your database is not empty). The attached query might give you a clue on how data can be prepared to get price/timestamp data displayed in the Plot visualization. After having run the query, you need to open the generated "test" database and enable the Plot visualization.
