The documentation of the Mendix ChartJS widget mentions the possibility of using a 'Onclick' microflow which "passes the dataview context object along" The term 'dataview context' does not make sense to me. What type of input paramter do I have to supply in my microflow? Is it a SingleSerieDataset, a MultiSeriesDataset or something completely else?
Is your ChartJS widget inside of a dataview? If so, the microflow would expect the dataview's entity as a parameter.
