Hey there, 

 

I am using Data query APIs to groupBy my data by priorities:

  this.piechartData = groupBy(chartData, [{field:"priority"}]);

Then I want to count the items per priority value to build the piechart. However, the aggregate="count" is not working for me. 

 

Is there

<kendo-chart>
                <kendo-chart-series>
                  <kendo-chart-series-item
                    type="donut"
                    *ngFor="let item of piechartData"
                    [data]="item.items"
                    [name]="item.value"
                    categoryField="priority"
                    aggregate="count"
                    field="taskName">
                  </kendo-chart-series-item>
                </kendo-chart-series>
                <kendo-chart-legend [visible]="false"></kendo-chart-legend>
            </kendo-chart>

a way around to do this?

I used this approach for barcharts and linecharts before and it worked.

 

Regards,

Nazareth

Hello, Nazareth,

Please check our Aggregate Pie Chart article which should guide you to the correct configuration. If it does not help you to resolve the problem, kindly provide a small runnable dojo example where I can observe the problem.
