Salesforce Lightning Web Components (LWC) provide a powerful framework for building dynamic user interfaces, and when combined with the Highcharts library, you can create stunning, interactive charts to showcase your data.

In this blog post, I’ll walk you through the implementation of interactive pie charts in Salesforce LWC using Highcharts. This solution allows users to switch between multiple datasets dynamically, making it perfect for dashboards, analytics, and reporting.

Why Highcharts?

Highcharts is a popular JavaScript library for creating interactive and responsive charts. It supports a wide range of chart types, including pie, bar, line, and more. With its rich customization options and ease of use, Highcharts is an excellent choice for visualizing data in Salesforce.

Key Features of the Implementation

  • Dynamic Pie Charts: Switch between multiple datasets using a dropdown menu.
  • Interactive Slices: Click on pie slices to highlight them and view detailed information.
  • Responsive Design: Charts automatically adjust to fit the container size.
  • Customizable: Easily add or modify datasets and chart configurations.

How It Works

The implementation consists of a Lightning Web Component that:

  1. Loads the Highcharts library as a static resource.
  2. Displays a dropdown menu for dataset selection.
  3. Renders an interactive pie chart based on the selected dataset.
  4. Updates the chart dynamically when the user selects a new dataset.

Step-by-Step Implementation

1. Upload Highcharts as a Static Resource

  1. Download the Highcharts library from the official website.
  2. In Salesforce, go to Setup → Static Resources → New.
  3. Upload the Highcharts file (e.g., highcharts.js) and name it Highcharts.
  4. Save the static resource.

2. Create the Lightning Web Component

The LWC component consists of three files (stored at GitHub Repo given below):

  • JavaScript File: Loads Highcharts and handles chart initialization and updates.
  • HTML File: Defines the dropdown and chart container.
  • Meta XML File: Exposes the component for use in Lightning App Builder.

3. Add the Component to a Lightning Page

  1. Go to the Lightning App Builder in Salesforce.
  2. Create or edit a Lightning Page (App Page, Record Page, or Home Page).
  3. Drag and drop the highchartsExample (or the name you given) component onto the page.
  4. Save and activate the page.
