You cannot change the legend to show the "sentence".
After some experimentation, I found that there is undocumented support for
changing the tooltip contents. I expect that this will be changed in the
future, as it doesn't behave the same way as custom tooltips in other
charts, but for now this should work. You need to rearrange your three
columns in this order: "Country", "Value", "Sentence", and set the "role"
property of the "Sentence" column to "tooltip". If you are using the
DataTable#addColumns method, it would be like this:
data.addColumn('string', 'Country');
data.addColumn('number', 'Value');
data.addColumn({type: 'string', label: 'Sentence', role: 'tooltip'});
or if using the arrayToDataTable method:
['Country', 'Value', {type: 'string', label: 'Sentence', role: 'tooltip'}]
