Would it be possible to define some more verbose commentary for parameters? The default is provided, but alternative parameters are not (so one has to guess about potential alternatives!) This should be possible, if only for parameters with a defined set of allowed values.
E.g., for the 'datalabels' parameter, I have figured out that "percent" and "label" and "value" are valid values for this parameter, from finding examples & guessing... but I have no idea if they are the only ones.
