Unfortunately, jpgraph is not maintained in composer. So the version that is installed "out of the box" with PhpSpreadsheet is a very old one, and results in the problem you are reporting. If you download the current version of jpgraph (4.4), and substitute that version in the vendor library, the sample scripts run correctly, without error or warnings messages. On my system, I discarded everything below vendor/jpgraph/jpgraph/lib/jpgraph (directory docs, directory src, and file VERSION), replacing them with docs, src, and VERSION from the current jpgraph image.

We can now use mitoteam/jpgraph, which is maintained in Composer, in place of jpgraph/jpgraph. Closing this issue.
