CanvasJS Charts

CanvasJS Charts is a JavaScript charting library that allows developers to add responsive, interactive data visualisations to web and hybrid applications. Presenting data clearly is essential for dashboards, analytics portals and reporting tools, but many charting libraries become sluggish when handling large datasets or require considerable effort to achieve a polished appearance. CanvasJS addresses this by rendering charts on the HTML5 Canvas element, an approach that delivers high performance even with hundreds of thousands of data points, and by exposing a simple, well-documented API. Its core approach is to combine speed with ease of use, so developers can produce attractive charts with a few lines of configuration while retaining control over styling, behaviour and events. The library works across modern desktop and mobile browsers and supports touch interaction for users on phones and tablets. This balance of performance and simplicity makes it suitable for everything from simple web pages to data-intensive analytical dashboards.

More than thirty chart types are supported, including line, area, column, bar, pie, doughnut, scatter, bubble, candlestick, OHLC, range, waterfall, funnel and pyramid charts, and a separate StockChart component serves financial and time-series applications with navigators and range selectors. Features include zooming and panning, animation, tooltips, crosshairs, dynamic and live-updating data, multiple axes, themes, annotations and export of charts as images. Integrations and samples are available for frameworks and platforms such as React, Angular, Vue, jQuery, ASP.NET MVC, PHP, JSP and Python-based stacks, and data can be loaded from JSON, CSV and XML sources. As a client-side library, CanvasJS is included directly in web projects and does not depend on external servers. It is used by software developers, SaaS companies, enterprises building internal dashboards, and educational institutions. Pricing starts from around USD 399 for a commercial licence, a free trial is available, and a free version can be used for non-commercial purposes.
