Bug found in the upgrade process from knowage 7.4.9 to 8.0.9
The update process found in the official documentation (https://knowage-suite.readthedocs.io/en/8.0/installation-guide/upgrade.html) has been carried out, and once done, there are fewer chart types to create than those offered in the documentation, that is to say, that during the update process several chart types have been lost.
