Range Column Chart in Angular Charts

3 Feb 202624 minutes to read

Range Column

To render a range column series in your chart, you need to follow a few steps to configure it correctly. Here’s a concise guide on how to do this:

  1. Set the series type: Define the series type as RangeColumn in your chart configuration. This indicates that the data should be represented as a range column chart, which is ideal for visualizing data that has both minimum and maximum values for each category. This is especially useful for visualizing data ranges, such as temperature fluctuations over time, stock prices, or any other data with upper and lower bounds.

  2. Inject the RangeColumnSeries module: Use the @NgModule.providers method to inject the RangeColumnSeriesService module into your chart. This step is essential, as it ensures that the necessary functionalities for rendering range column series are available in your chart.

  3. Provide high and low values: The RangeColumn series requires two y-values for each data point, you need to specify both the high and low values. The high value represents the maximum range, while the low value represents the minimum range for each data point. These values define the upper and lower boundaries of the column for each point on the chart.

Binding data with series

You can bind data to the chart using the dataSource property within the series configuration. This allows you to connect a JSON dataset or remote data to your chart. To display the data correctly, map the fields from the data to the chart series xName, high, and low properties.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule } from '@syncfusion/ej2-angular-charts'

    ChartAnnotationService, RangeColumnSeriesService, StackingColumnSeriesService,LegendService, TooltipService

    template: `<ejs-chart id="chart-container" [primaryXAxis]='primaryXAxis'[primaryYAxis]='primaryYAxis' [title]='title'>

            <e-series [dataSource]='data2' type='RangeColumn' xName='x' low='low' high='high'></e-series>
        </e-series-collection>
    </ejs-chart>`
})

export class AppComponent implements OnInit {
    public primaryXAxis?: Object;

        };
        this.title = 'Maximum and minimum Temperature';
    }
}

Series customization

The following properties can be used to customize the range column series.

Fill

The fill property determines the color applied to the series.

import { BrowserModule } from '@angular/platform-browser'
import { ChartModule } from '@syncfusion/ej2-angular-charts'
import { CategoryService, DateTimeService, ScrollBarService, ColumnSeriesService, LineSeriesService, 
    ChartAnnotationService, RangeColumnSeriesService, StackingColumnSeriesService,LegendService, TooltipService
 } from '@syncfusion/ej2-angular-charts'



import { Component, OnInit } from '@angular/core';
import { data1 } from './datasource';
import { data2 } from './datasource';
@Component({
imports: [
         ChartModule
    ],

providers: [ CategoryService, DateTimeService, ScrollBarService, LineSeriesService, ColumnSeriesService, 
        ChartAnnotationService, RangeColumnSeriesService, StackingColumnSeriesService, LegendService, TooltipService,],
standalone: true,
    selector: 'app-container',
    template: `<ejs-chart id="chart-container" [primaryXAxis]='primaryXAxis' [title]='title'>
        <e-series-collection>
            <e-series [dataSource]='data1' type='RangeColumn' xName='x' low='low' high='high' fill='red' ></e-series>
            <e-series [dataSource]='data2' type='RangeColumn' xName='x' low='low' high='high' fill='yellow' ></e-series>
        </e-series-collection>
    </ejs-chart>`
})

export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public border?: Object;
    public title?: string;
    public data1?: Object[];
    public data2?: Object[];
    ngOnInit(): void {
        this.data1 = data1;
        this.data2 = data2;
        this.primaryXAxis = {
            title: 'month',
            valueType: 'Category'
        };
        this.title = 'Maximum and minimum Temperature';
    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
export let data1: Object[] = [
        { x: 'Jan', low: 0.7, high: 6.1 }, { x: 'Feb', low: 1.3, high: 6.3 }, { x: 'Mar', low: 1.9, high: 8.5 },
        { x: 'Apr', low: 3.1, high: 10.8 }, { x: 'May', low: 5.7, high: 14.40 }, { x: 'Jun', low: 8.4, high: 16.90 },
        { x: 'Jul', low: 10.6, high: 19.20 }, { x: 'Aug', low: 10.5, high: 18.9 }, { x: 'Sep', low: 8.5, high: 16.1 },
        { x: 'Oct', low: 6.0, high: 12.5 }, { x: 'Nov', low: 1.5, high: 6.9 }, { x: 'Dec', low: 5.1, high: 12.1 }
];
export let data2: Object[] = [
        { x: 'Jan', low: 1.7, high: 7.1 }, { x: 'Feb', low: 1.9, high: 7.7 }, { x: 'Mar', low: 1.2, high: 7.5 },
        { x: 'Apr', low: 2.5, high: 9.8 }, { x: 'May', low: 4.7, high: 11.4 }, { x: 'Jun', low: 6.4, high: 14.4 },
        { x: 'Jul', low: 9.6, high: 17.2 }, { x: 'Aug', low: 10.7, high: 17.9 }, { x: 'Sep', low: 7.5, high: 15.1 },
        { x: 'Oct', low: 3.0, high: 10.5 }, { x: 'Nov', low: 1.2, high: 7.9 }, { x: 'Dec', low: 4.1, high: 9.1 }
];

The fill property can be used to apply a gradient color to the range column series. By configuring this property with gradient values, you can create a visually appealing effect in which the color transitions smoothly from one shade to another.

Use the mode property to control handling of empty points. Available modes: Gap, Drop, Zero, Average. The default mode is Gap.

Corner radius

The cornerRadius property in the chart series is used to customize the corner radius for range column series. This allows you to create range columns with rounded corners, giving your chart a more polished appearance. You can customize each corner of the range columns using the topLeft, topRight, bottomLeft, and bottomRight properties.

Events

Series render

The seriesRender event enables modification of series properties (for example, data, fill, or name) immediately before rendering. Use this event to adjust series appearance or to dynamically swap data sources.

Point render

The pointRender event provides a hook to customize each data point (for example, marker shape, border, or fill) before it is drawn. Use this to apply per-point styling rules or conditional formatting.
