Customizing Chart Area Background Color in Chart.js: From CSS Basics to Plugin Implementation
This article provides an in-depth exploration of methods to customize the background color of chart areas in Chart.js. It begins by analyzing the limitations of Chart.js native API, noting the absence of direct background color configuration.
