The rendered chart can be printed directly from the browser by calling the public method print. ID of the chart div element must be passed as argument to that method.

index.ts
index.html
import { Chart, ColumnSeries, Category, Legend } from '@syncfusion/ej2-charts';
Chart.Inject(ColumnSeries, Category, Legend);
import { Button } from '@syncfusion/ej2-buttons';
import { EmitType } from '@syncfusion/ej2-base';

let chart: Chart = new Chart({
        //Initializing Primary X Axis
        primaryXAxis: {
            title: 'Manager',
            valueType: 'Category',
            majorGridLines: { width: 0 }

        },

            title: 'Sales',
            minimum: 0,
            maximum: 20000,
            majorGridLines: { width: 0 }
        },

Export

The rendered chart can be exported to JPEG, PNG, SVG, PDF, XLSX, or CSV format using the export method in chart. The input parameters for this method are type for format and fileName for result.

The optional parameters for this method are,

orientation - either portrait or landscape mode during PDF export,
controls - pass collections of controls for multiple export,
width - width of chart export, and
height - height of chart export.

        fontSize: 15
    };

    const footer = {
        content: 'Chart Footer',
        fontSize: 15,

Multiple chart export

You can export the multiple charts in single page by passing the multiple chart objects in the export method of chart. To export multiple charts in a single page, follow the given steps:

Initially, render more than one chart to export, and then add button to export the multiple charts. In button click, call the export method in charts, and then pass the multiple chart objects in the export method.

Exporting chart using base64 string

The chart can be exported as an image in the form of a base64 string by utilizing HTML canvas. This process involves rendering the chart onto a canvas element and then converting the canvas content to a base64 string.

index.ts
index.html
import { Chart, ColumnSeries, Category, Legend, Tooltip } from '@syncfusion/ej2-charts';

Chart.Inject(ColumnSeries, Category, Legend, Tooltip);

        primaryXAxis: {
            valueType: 'Category',
            majorGridLines: { width: 0 },
            majorTickLines: { width: 0 },
            minorTickLines: { width: 0 }
        },

        //Initializing Primary Y Axis
        primaryYAxis:
        {
