Note: To use the data label feature, inject the DataLabel module into the services.

Positioning

Accumulation chart provides support for placing the data label either inside or outside the chart.

DataLabel rotation

Using angle property, you can rotate the data label by its given angle.

    </AccumulationChartComponent>
  }

};
ReactDOM.render(<App />, document.getElementById("charts"));

Note: By default, when the enableRotation is true, the datalabel is rotated along the slice.

Smart labels

Data labels will be arranged smartly without overlapping with each other. You can enable or disable this feature using the enableSmartLabels property.

Format

Data label for the accumulation chart can be formatted using format property. You can use the global formatting options, such as ‘n’, ‘p’, and ‘c’.

Datalabel template

Label content can be formatted by using the template option. Inside the template, you can add the placeholder text ${point.x} and ${point.y} to display corresponding data points x & y value. Using templateproperty, you can set data label template in chart.
