In Chart.js, there are a few different ways to accomplish this.

Animations can be easily added in charts created using Chart.js library. To add animation in a chart animations object is passed to the options object of Chart.
We know that Chart.js uses colors as its background to plot charts. Do you know that we can also use an image as a background for these datasets?
To add a title on the top of the chart, the below code can be used. Chart.js uses the subtitle object to define your subtitle text and style them.
By default, Chart.js maintains the aspect ratio with the width and height of the chart. If you want to assign a fixed height to a chart you can set maintainAspectRatio property to false.
If you want to assign a fixed width to the bars of the bar chart created using the Chart.js library. You can use barThickness property of datasets.
In Chart.js, the y-axis shows the scale values based on that the chart is plotted. If you have a requirement to hide these scale values labels, then you can use this code snippet.
By default, chart.js display all the label texts on both axis(x-axis and y-axis). You can hide them by using the below code.

You can assign minimum and maximum values to the y-axis in Chart.js. We can do that by assigning a value to the max property to the y-axis.
To hide data points tooltips that are enabled by default, you can use the below code in your Chart.js code.
If you want to show data values labels on Chart.js, then you can use the chartjs-plugin-datalabels. This will display values on the chart on top or bottom of the chart area.
