Setting Font Weight in Chart Js

Customizing font weight in Chart.js is a straightforward process that can be done using the “font” property in the configuration options of your chart. You can specify the font weight using the CSS font-weight property, which accepts values such as “normal”, “bold”, “bolder”, “lighter”, or numeric values ranging from 100 to 900.

For example, to set the font weight of the title of your chart to bold, you can use the following code snippet:

options: title: display: true, text: 'Chart Title', font: weight: 'bold'

In addition to customizing the font weight of the title of your chart, you can also customize the font weight of data labels, axis labels, and tooltips in Chart.js. By setting the font weight for these elements, you can create a cohesive and visually appealing design for your chart.

For example, to set the font weight of the data labels in your chart to a numeric value of 600, you can use the following code snippet:

options: scales: y: ticks: font: weight: 600
