By Configuring Scales Options (Using beginAtZero)

Approach 2: By Custom Tick Callback

In this approach, we Utilize the scale arrangement’s beginAtZero: genuine boundary. Regardless of what your information range is, this clear change ensures that the y-hub generally begins at 0.

Syntax:

 options: {
                scales: {
                    y: {
                        beginAtZero: true
                    }
                }
            }

Example: This example shows the implementation of the above-explained approach.
