Pie Chart Series

[Richard]

Good afternoon,

I have created a pie chart based on a ViewModel that contains:
int OperatorId,
string OperatorName,
int OperatorTotal

The chart series is created with a click event as:

            .Series(series => series
                    .Pie(model => model.OperatorTotal, model => model.OperatorName)
                    .ColorField("Color")
                    .Padding(0)
            )
            .Events(events => events.SeriesClick("onPieChartClick"))

I can access e.series.name and e.category in the click event which gives me the OperatorName, but I really need the OperatorId.

Is there a way that I can group the pie chart by Id but display the name, or pass the Id in the click event?

Many thanks

Richard

Hello Richard,

Thank you for the comprehensive explanation of the scenario at hand. 

The SeriesClick event also exposes a dataItem property which holds the series' Model item. To access it use the e.dataItem syntax.

function onPieChartClick(e){
     console.log(e.dataItem);
}

I hope this information is useful. Please let me know, if further questions on the topic arise. Thank you.
