8 May 20239 minutes to read
By using the annotation, you can show any element in desired view.
To show the total value in data points, follow the given steps:
Step 1:
Define annotation for each x point in chart, now change the annotation value in chart by using the annotationRender event. In this event, assign the stacked value of the last series to the annotation to show the total value of the
stacking series.
import { ChartAnnotation, Chart, StackingColumnSeries, Category, DataLabel, Tooltip, ILoadedEventArgs,IAnnotationRenderEventArgs, Points } from '@syncfusion/ej2-charts';
Chart.Inject(StackingColumnSeries, ChartAnnotation, DataLabel, Category, Tooltip);
import { EmitType } from '@syncfusion/ej2-base';
let i: number = 0;
let chart: Chart = new Chart({
//Initializing Primary X and Y Axis
primaryXAxis: {
valueType: 'Category', interval: 1
},
// Initialize the chart series
series: [
