      I have a patch adding support for Area Charts as per: https://www.chartjs.org/docs/2.7.0/charts/area.html

      This involves adding fields, getters and setters to the Series classes in both PHP and Javascript. From Moodle code, it's a matter of invoking e.g. $series->set_fill('-1').

      An example is provided in the patch to tests/other/chartjstestpage.php.
