Install FusionCharts and Configure Angular

FusionCharts provides an Angular wrapper that makes it easy to integrate interactive charts into Angular applications.

Install FusionCharts and the Angular integration package using npm:

npm install fusioncharts angular-fusioncharts --save

Angular 17 and above versions use standalone components by default, so there is no app.module.ts file. Instead, FusionCharts can be configured directly inside the application component.

Open the src/app/app.component.ts file and import the required FusionCharts modules.

import { Component } from '@angular/core';
import { FusionChartsModule } from 'angular-fusioncharts';

import * as FusionCharts from 'fusioncharts';
import * as Charts from 'fusioncharts/fusioncharts.charts';
import * as FusionTheme from 'fusioncharts/themes/fusioncharts.theme.fusion';

// Register FusionCharts modules
FusionChartsModule.fcRoot(
  FusionCharts,
  Charts,
  FusionTheme
);

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [FusionChartsModule],
  templateUrl: './app.component.html',
  styleUrl: './app.component.css'
})
export class AppComponent {
}

Prepare the Chart Data

Let’s create a chart that visualizes monthly website traffic.

The following dataset shows monthly website traffic from January to June, categorized by traffic source.

Since we’re working with multiple datasets, a Stacked Column Chart is a suitable choice. The months will be displayed along the x-axis, while visitor counts from different traffic sources will be stacked on the y-axis, making it easy to compare both total traffic and source contributions across months.

FusionCharts accepts data in JSON format, so we’ll convert the table into the following structure:

// Preparing the chart data
const dataSource = {
    categories: [
    {
      category: [
        { label: "Jan" },
        { label: "Feb" },
        { label: "Mar" },
        { label: "Apr" },
        { label: "May" },
        { label: "Jun" }
      ]
    }
  ],
  dataset: [
    {
      seriesname: "Organic Search",
      data: [
        { value: "6000" },
        { value: "7000" },
        { value: "6500" },
        { value: "8000" },
        { value: "9500" },
        { value: "11000" }
      ]
    },
    {
      seriesname: "Social Media",
      data: [
        { value: "3000" },
        { value: "3500" },
        { value: "3200" },
        { value: "3800" },
        { value: "4200" },
        { value: "4500" }
      ]
    },
    {
      seriesname: "Direct Traffic",
      data: [
        { value: "3000" },
        { value: "4000" },
        { value: "3500" },
        { value: "5000" },
        { value: "5700" },
        { value: "6600" }
      ]
    }
  ]
};

The category labels represent the months, while each dataset contains visitor counts for a specific traffic source. FusionCharts uses this structured JSON format to generate the stacked column chart.

Configure the Chart

Now that the data is ready, the next step is to configure the chart. This includes defining the chart title, axis labels, theme, and other settings that help users understand the data being displayed.

const dataSource = {
  chart: {
caption: "Monthly Website Traffic by Source",
subCaption: "January - June 2026",
xAxisName: "Month",
yAxisName: "Visitors",
theme: "fusion"
},
  data: chartData
};

In this configuration:

• caption defines the main chart title.
• subCaption provides additional context about the displayed data.
• xAxisName labels the horizontal axis.
• yAxisName labels the vertical axis.
• theme applies the FusionCharts visual theme.
• categories define the labels displayed along the x-axis.
• dataset contains the individual data series that will be stacked in the chart.
• seriesname identifies each traffic source in the chart legend.
• dataSource combines the chart settings and data into a single object that FusionCharts uses to render the visualization.

Add the Chart to Your Angular Component

Next, add the chart configuration and data source to src/app/app.component.ts. FusionCharts uses the dataSource object to combine chart settings, category labels, and datasets into a single configuration that the chart component can render.

export class AppComponent {

  dataSource = {
    chart: {
      caption: "Monthly Website Traffic by Source",
      subCaption: "January - June 2026",
      xAxisName: "Month",
      yAxisName: "Visitors",
      theme: "fusion"
    },
    categories: [
      {
        category: [
          { label: "Jan" },
          { label: "Feb" },
          { label: "Mar" },
          { label: "Apr" },
          { label: "May" },
          { label: "Jun" }
        ]
      }
    ],
    dataset: [
      {
        seriesname: "Organic Search",
        data: [
          { value: "6000" },
          { value: "7000" },
          { value: "6500" },
          { value: "8000" },
          { value: "9500" },
          { value: "11000" }
        ]
      },
      {
        seriesname: "Social Media",
        data: [
          { value: "3000" },
          { value: "3500" },
          { value: "3200" },
          { value: "3800" },
          { value: "4200" },
          { value: "4500" }
        ]
      },
      {
        seriesname: "Direct Traffic",
        data: [
          { value: "3000" },
          { value: "4000" },
          { value: "3500" },
          { value: "5000" },
          { value: "5700" },
          { value: "6600" }
        ]
      }
    ]
  };
}

This configuration creates a stacked column chart that displays monthly website traffic and shows how Organic Search, Social Media, and Direct Traffic contribute to the overall visitor count each month.

Render the Chart

Finally, open src/app/app.component.html and add the FusionCharts component:

<fusioncharts
  width="50%"
  height="500"
  type="stackedcolumn3d"
  dataFormat="json"
  [dataSource]="dataSource">
</fusioncharts>

The type attribute determines which chart type FusionCharts renders. In this example, we’re using a Stacked Column 3D Chart (stackedcolumn3d) to visualize monthly website traffic by source.

A stacked column chart allows you to compare both the total monthly traffic and the contribution of individual traffic sources. Each column represents the total number of visitors for a month, while the stacked segments show how Organic Search, Social Media, and Direct Traffic contribute to that total.

FusionCharts supports more than 100 chart types, including line charts, bar charts, pie charts, area charts, scatter charts, Gantt charts, maps, gauges, and real-time charts, making it easy to choose the visualization that best fits your data and use case.

Result

Save your files and return to your browser. Angular will automatically reload the application and render the chart.

You should now see an interactive column chart displaying monthly website traffic from January through June, complete with tooltips, responsive behavior, and FusionCharts styling.

Angular Charts Best Practices

Following a few best practices can improve both the usability and performance of your Angular charts. They also help create a consistent experience across different devices and screen sizes.

Keep Visualizations Simple: Avoid overcrowding your charts with too many data points, labels, or visual elements. A clean and focused chart helps users quickly understand the information without distractions.

Use Responsive Layouts: Ensure your charts adapt seamlessly to different screen sizes and devices. Responsive charts provide a consistent user experience across desktops, tablets, and mobile phones.

Optimize Large Datasets: Large datasets can impact chart performance and readability. Consider aggregating data, limiting the displayed range, or using pagination and drill-down features to improve both speed and usability.

Use Consistent Colors: Maintain a consistent color scheme throughout your application or dashboard. Consistent colors help users recognize data categories more easily and improve overall readability.

Choose the Right Chart Type: Select a chart type that best represents your data and the story you want to tell. For example, use line charts for trends over time, bar charts for comparisons, and pie charts for showing proportions.
