Bar Chart in EJ2 TypeScript control
20 Sep 202424 minutes to read
Bar
To render a bar 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:
-
Set the series type: Define the series
type
asBar
in your chart configuration. This indicates that the data should be represented as a bar chart, which makes it easy to compare values across categories. -
Inject the BarSeries module: Use the
Chart.Inject(BarSeries)
method to inject theBarSeries
module into your chart. This step is essential, as it ensures that the necessary functionalities for rendering bar series are available in your chart.
import { Chart, BarSeries, Category } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(BarSeries, Category);
let chart: Chart = new Chart({
primaryXAxis: {
minimum: 2005,
maximum: 2012,
interval: 1,
title: 'Year'
},
primaryYAxis: {
minimum: 3,
maximum: 12,
interval: 1,
title: 'Percentage',
labelFormat: '{value}%'
},
series:[{
dataSource: chartData,
xName: 'x', yName: 'y',
// Series type as bar series
type: 'Bar'
}],
title: 'Unemployment rate (%)'
}, '#element');

{ x: 2009, y: 10.7 },
{ x: 2010, y: 10.8},
{ x: 2011, y: 9.8 }
];
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
and yName
properties.
import { Chart, BarSeries, Category } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(BarSeries, Category);
let chart: Chart = new Chart({
primaryXAxis: {
minimum: 2005,
maximum: 2012,
interval: 1,
title: 'Year'
},
primaryYAxis: {
minimum: 3,
maximum: 12,
interval: 1,
title: 'Percentage',
labelFormat: '{value}%'
},
series:[{
dataSource: chartData,
xName: 'x', yName: 'y',
// Series type as bar series
type: 'Bar'
}],
title: 'Unemployment rate (%)'
}, '#element');

Series customization
The following properties can be used to customize the bar
series.
Fill
The fill property determines the color applied to the series.
import { Chart, BarSeries, Category } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(BarSeries, Category);
let chart: Chart = new Chart({
primaryXAxis: {
minimum: 2005,
maximum: 2012,
interval: 1,
title: 'Year'
},
primaryYAxis: {
minimum: 3,
maximum: 12,
interval: 1,
title: 'Percentage',
labelFormat: '{value}%'
},
series:[{
dataSource: chartData,
xName: 'x', yName: 'y',
// Series type as bar series
type: 'Bar',
fill: 'blue'
}],
title: 'Unemployment rate (%)'
}, '#element');

{ x: 2009, y: 10.7 },
{ x: 2010, y: 10.8},
{ x: 2011, y: 9.8 }
];
The fill property can be used to apply a gradient color to the bar 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.
import { Chart, BarSeries, Category } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(BarSeries, Category);
let chart: Chart = new Chart({
primaryXAxis: {
minimum: 2005,
maximum: 2012,
interval: 1,
title: 'Year'
},
primaryYAxis: {
minimum: 3,
maximum: 12,
interval: 1,
title: 'Percentage',
labelFormat: '{value}%'
},
series:[{
dataSource: chartData,
xName: 'x', yName: 'y',
// Series type as bar series
type: 'Bar',
fill: 'url(#gradient)'
}],
title: 'Unemployment rate (%)'
}, '#element');

{ x: 2011, y: 9.8 }
];
Opacity
The opacity property specifies the transparency level of the fill. Adjusting this property allows you to control how opaque or transparent the fill color of the series appears.
import { Chart, BarSeries, Category } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(BarSeries, Category);

// Series type as bar series
type: 'Bar',
opacity: 0.5

];
Dash array
The dashArray property determines the pattern of dashes and gaps in the series.
import { Chart, BarSeries, Category } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(BarSeries, Category);

Bar space and width
Bar space
Use the columnSpacing
property in the series to adjust the space between bars.
import { Chart, BarSeries, Category } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(BarSeries, Category);
let chart: Chart = new Chart({

Bar width
Use the columnWidth
property in the series to adjust the width of the bars.
import { Chart, BarSeries, Category } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(BarSeries, Category);
let chart: Chart = new Chart({

Bar width in pixel
Use the columnWidthInPixel
property in the series to define the exact width of the bars in pixels. This property ensures that each bar maintains the specified width, providing a uniform appearance throughout the chart.
import { Chart, BarSeries, Category } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(BarSeries, Category);
let chart: Chart = new Chart({
primaryXAxis: {
minimum: 2004,

title: 'Year'
},
primaryYAxis: {

Grouped bar
Use the groupName
property to group the data points in bar type charts. Data points with the same group name will be grouped together in the chart, making it easy to compare different sets of data.
import { Chart, BarSeries, Category } from '@syncfusion/ej2-charts';
import { data1, data2, data3, data4 } from './datasource.ts';
Chart.Inject(BarSeries, Category);
let chart: Chart = new Chart({
primaryXAxis: {
valueType: 'Category'
},
series: [
{
type: 'Bar', xName: 'x', yName: 'y', groupName: 'USA', columnWidth: 0.7,
dataSource: data1, columnSpacing: 0.1,
},
{
type: 'Bar', xName: 'x', yName: 'y', groupName: 'USA', columnWidth: 0.5,
dataSource: data2, columnSpacing: 0.1,
},
{
type: 'Bar', xName: 'x', yName: 'y', groupName: 'UK', columnWidth: 0.7,
dataSource: data3, columnSpacing: 0.1,
},
{
type: 'Bar', xName: 'x', yName: 'y', groupName: 'UK', columnWidth: 0.5,
dataSource: data4, columnSpacing: 0.1,
}
]
}, '#element');

Cylindrical bar chart
To render a cylindrical bar chart, set the columnFacet
property to Cylinder
in the chart series. This property transforms the regular bars into cylindrical shapes, enhancing the visual representation of the data.
import { Chart, BarSeries, Category } from '@syncfusion/ej2-charts';
import { cylindricalData } from './datasource.ts';
Chart.Inject(BarSeries, Category);
let chart: Chart = new Chart({
primaryXAxis: {
minimum: 2005,
maximum: 2012,
interval: 1,
title: 'Year'
},
primaryYAxis: {
minimum: 3,
maximum: 12,
interval: 1,
title: 'Percentage',
labelFormat: '{value}%'
},
series: [{
dataSource: cylindricalData,
xName: 'x', yName: 'y',
// Series type as bar series with cylinder shape
type: 'Bar', columnFacet: 'Cylinder'
}],
title: 'Unemployment rate in percentage'
}, '#element');

Empty points
Data points with null
or undefined
values are considered empty. Empty data points are ignored and not plotted on the chart.
Mode
Use the mode
property to define how empty or missing data points are handled in the series. The default mode for empty points is Gap
.

Events
Series render
The seriesRender
event allows you to customize series properties, such as data, fill, and name, before they are rendered on the chart.
import { Chart, BarSeries, Category, ISeriesRenderEventArgs } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(BarSeries, Category);
let chart: Chart = new Chart({
primaryXAxis: {
minimum: 2005,
maximum: 2012,
interval: 1,
title: 'Year'
},
primaryYAxis: {
minimum: 3,
maximum: 12,
interval: 1,
title: 'Percentage',
labelFormat: '{value}%'
},
series:[{
dataSource: chartData,
xName: 'x', yName: 'y',
// Series type as bar series
type: 'Bar'
}],
title: 'Unemployment rate (%)',
seriesRender: (args: ISeriesRenderEventArgs) => {
args.fill = '#ff6347';
}
}, '#element');
export let chartData: Object[] = [
{ x: 2006, y: 7.8 },
{ x: 2007, y: 7.2 },
{ x: 2008, y: 6.8 },
{ x: 2009, y: 10.7 },
{ x: 2010, y: 10.8},
{ x: 2011, y: 9.8 }
];
Point render
The pointRender
event allows you to customize each data point before it is rendered on the chart.
import { Chart, BarSeries, Category, IPointRenderEventArgs } from '@syncfusion/ej2-charts';
import { chartData } from './datasource.ts';
Chart.Inject(BarSeries, Category);
let chart: Chart = new Chart({
primaryXAxis: {
minimum: 2005,
maximum: 2012,
interval: 1,
title: 'Year'
},
primaryYAxis: {
minimum: 3,
maximum: 12,
interval: 1,
title: 'Percentage',
labelFormat: '{value}%'
},
series:[{
dataSource: chartData,
xName: 'x', yName: 'y',
// Series type as bar series
type: 'Bar'
}],
title: 'Unemployment rate (%)',
pointRender: (args: IPointRenderEventArgs) => {
if (args.point.y < 7.5) {
args.fill = '#ff6347';
}
else {
args.fill = '#009cb8';
}
}
}, '#element');
