A very simple plugin to allow a logged in user to record their weight (Kg or St) on given dates. This data is then shown in a graph (chart.js) and table.  Place the tag [weightlosstracker] on a given page and the user is presented with a form to enter a date, weight (Kg or St) and notes for that entry. When the person saves their entry the data table and graph is refreshed.  If data is entered for an existing date, then the previous entry is simply updated. The graph is shown when there are two or more entries.
