Numeric Axis

You can use numeric axis to represent numeric values of data in chart. By default, the valueType of an axis is Double.

index.tsx
import * as React from "react";
import * as ReactDOM from "react-dom";
import { AxisModel, ChartComponent, SeriesCollectionDirective, AxesDirective, AxisDirective, SeriesDirective, Inject,
ColumnSeries, Legend, Category, Tooltip, DataLabel, Zoom, Crosshair, AreaSeries, Selection}
from'@syncfusion/ej2-react-charts';
import { numericData } from 'datasource.ts';

class App extends React.Component<{}, {}> {

  public primaryxAxis: AxisModel = { valueType: 'Double', title: 'Overs' };
  public primaryyAxis: AxisModel = { title: 'Runs' };

  render() {
    return <ChartComponent id='charts' primaryXAxis={this.primaryxAxis}
      primaryYAxis={this.primaryyAxis}
      title='England - Run Rate'>
      <Inject services={[ColumnSeries, Legend, Tooltip, DataLabel, AreaSeries, Category]} />
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={numericData} xName='x' yName='y' name='England' type='Area'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>
  }

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

Range

Range for an axis, will be calculated automatically based on the provided data, you can also customize the range of the axis using minimum, maximum and interval property of the axis.

    return <ChartComponent id='charts'
      primaryXAxis={this.primaryxAxis}

        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>
  }

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

Range Padding

Padding can be applied to the minimum and maximum extremes of the axis range by using the rangePadding property. Numeric axis supports following types of padding.

  • None
  • Round
  • Additional
  • Normal
  • Auto

Numeric - None

When the rangePadding is set to None, minimum and maximum of an axis is based on the data.

        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>
  }

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

Numeric - Round

When the rangePadding is set to Round, minimum and maximum will be rounded to the nearest possible value divisible by interval. For example, when the minimum is 3.5 and the interval is 1, then the minimum will be rounded to 3.

Numeric - Additional

When the rangePadding is set to Additional, interval of an axis will be padded to the minimum and maximum of the axis.

Numeric - Auto

When the rangePadding is set to Auto,horizontal numeric axis takes None as padding calculation, while the vertical numeric axis takes Normal as padding calculation.

The following table describes the result of applying some commonly used label formats on numeric values.

Label Value Label Format property value Result Description
1000 n1 1000.0 The Number is rounded to 1 decimal place
1000 n2 1000.00 The Number is rounded to 2 decimal place
1000 n3 1000.000 The Number is rounded to 3 decimal place
0.01 p1 1.0% The Number is converted to percentage with 1 decimal place
0.01 p2 1.00% The Number is converted to percentage with 2 decimal place
0.01 p3 1.000% The Number is converted to percentage with 3 decimal place
1000 c1 $1000.0 The Currency symbol is appended to number and number is rounded to 1 decimal place
1000 c2 $1000.00 The Currency symbol is appended to number and number is rounded to 2 decimal place
