In Chart.js, the easing option controls the easing function used for animations, which affects how the animation progresses over time.
The easing functions define the pace of the animation, creating effects like bouncing, elastic movements, or smooth transitions.
Here are the different easing options available in Chart.js:
link1. Linear
'linear': The animation progresses at a constant speed from start to finish.
Example: A linear motion with no acceleration or deceleration.
link2. Ease-In
'easeInQuad': The animation starts slowly and accelerates as it progresses.
'easeInCubic': Similar to easeInQuad, but with a more pronounced acceleration.
'easeInQuart': Even stronger acceleration than cubic.
'easeInQuint': The strongest acceleration among the ease-in options.
link3. Ease-Out
'easeOutQuad': The animation starts fast and decelerates towards the end.
'easeOutCubic': Similar to easeOutQuad, but with a more pronounced deceleration.
'easeOutQuart': Even stronger deceleration than cubic.
'easeOutQuint': The strongest deceleration among the ease-out options.
link4. Ease-In-Out
'easeInOutQuad': The animation starts slow, accelerates, and then decelerates towards the end.
'easeInOutCubic': A more pronounced version of easeInOutQuad.
'easeInOutQuart': Stronger acceleration and deceleration than cubic.
'easeInOutQuint': The strongest acceleration and deceleration among ease-in-out options.
link5. Bounce
'easeOutBounce': The animation moves quickly at first, then bounces at the end.
'easeInBounce': The animation starts with a bounce and then accelerates.
'easeInOutBounce': Combines both easeInBounce and easeOutBounce, creating a bounce at both the start and the end.
link6. Elastic
'easeOutElastic': The animation overshoots a bit and then snaps back into place, like an elastic band.
'easeInElastic': The animation starts by snapping into place, then overshoots.
'easeInOutElastic': A combination of easeInElastic and easeOutElastic.
link7. Back
'easeOutBack': The animation moves slightly past its endpoint and then returns to finish.
'easeInBack': The animation begins by moving slightly back before progressing forward.
'easeInOutBack': A combination of easeInBack and easeOutBack, with slight overshoot at the start and end.
linkExplanation:
HTML Setup: The dropdown and canvas are included in the HTML. The canvas element will be used to render the chart.
JavaScript:
Initial Setup: Initializes the Chart.js chart with the selected easing function from the dropdown.
Event Listener: Adds an event listener to the dropdown that updates the chart's easing function whenever the user selects a different option. It then calls myChart.update() to apply the new easing function and re-render the chart.
With this setup, the chart will dynamically update its animation easing function based on the user’s selection from the dropdown.
