Fixing the Highcharts Menu Button Issue in React: How to Properly Toggle Fullscreen Mode

When working with Highcharts in a React application, developers sometimes encounter frustrating bugs. One particularly annoying issue arises when the menu button fails to update from "View Full Screen" to "Exit Full Screen" when entering fullscreen mode. Instead, developers find that the button still displays "View in Full Screen," even though clicking it correctly exits the fullscreen mode.

In this guide, we'll explore the problem in deeper detail and guide you through the steps required to solve it effectively.

Understanding the Problem

The problem manifests when the chart is rendered in fullscreen mode. The typical expectation is for the menu button to reflect the current state, which means it should correctly indicate whether you are in fullscreen mode or not. Below is a summary of the preferences:

Expected Behavior: The menu should change the text to "Exit Full Screen" when in fullscreen mode.

Actual Behavior: The menu still states "View in Full Screen," creating confusion for users.

Solution Breakdown

Step 1: Identifying the Code

Initially, let’s take a look at the relevant codes within the useEffect hook that handles chart loading and updates.

The code sets the chart options upon loading, but it initializes and assigns an event within the useEffect, which can lead to issues in state management.

Step 2: Remove the Load Event from useEffect

To fix the issue at hand, it’s recommended to remove the load event from the useEffect hook. This should be defined within the chart configuration itself and passed as a parameter to the options function.

Here's the revised code structure for the chart options:

Step 3: Adjust Hook for State Management

Next, in the useEffect hook, we need to define our load function and appropriately manage the state:

This approach ensures that the correct load function is called, solving the problem of the menu button not updating properly.

Conclusion

By following these steps—removing the load event from the useEffect hook and correctly integrating it into the chart options—you can fix the issue of the Highcharts menu button in a React project. This not only makes your application more user-friendly but also enhances user experience by providing clarity on the current state of the chart within the interface.
