Visualize Hierarchies with Dendrogram Charts

January 22, 2026
Highcharts 12.5 adds dendrogram support, enabling clear visualization of hierarchical structures and similarity relationships across complex data.

Highcharts is a JavaScript charting framework that allows web developers and data analysts to generate dynamic, visually appealing charts and graphs for websites and web applications. It can display a variety of chart types, including line, spline, area, column, bar, pie, scatter, and many more. Highcharts is well-known for its ease of use, rich documentation, and ability to handle huge datasets efficiently. Features include responsive design, accessibility support, and cross-browser compatibility. Its customization capabilities allow users to create bespoke data visualizations that increase engagement and provide insightful data presentations.

The Highcharts 12.5 update introduces dendrogram support, allowing developers to visualize hierarchical relationships and similarity levels directly within their charts using treegraph-based diagrams. This enhancement makes it easier to represent the output of hierarchical clustering algorithms, taxonomies, and other structured datasets in a clear and interpretable way. By mapping similarity or progression along an axis and using branch height to indicate relationships, developers can present complex hierarchical data more effectively.

To see a full list of what's new in 12.5, see our release notes.

Highcharts Core is licensed on an annual or perpetual basis, OEM licenses, and Advantage Renewals. It is licensed per Developer and has several license options including Internal, SaaS, SaaS+, and Self Hosted. See our Highcharts Core licensing page for full details.

Add Keyboard Navigation to Charts in .NET

January 19, 2026
Enhance chart accessibility in .NET applications by enabling keyboard navigation for smoother data exploration and improved user experience.

Charts with keyboard navigation support are designed to improve accessibility and usability by allowing users to explore chart data using only the keyboard. This feature is especially valuable for users who rely on assistive technologies or prefer keyboard interaction over a mouse. It typically includes capabilities like navigating between data points, series, or chart elements using arrow keys, accessing tooltips or data labels, and sometimes triggering events like selection or focus changes, all through the keyboard.

Several .NET chart components support keyboard navigation, including:

  • DevExpress ASP.NET MVC Chart (part of DevExpress ASP.NET and Blazor) supports accessibility features, allowing keyboard interaction across UI components.
  • Telerik UI for ASP.NET Core Charts (part of Telerik UI for ASP.NET Core) includes support for arrow key movement between data points and ARIA integration.
  • jQWidgets Chart (part of jQWidgets) is part of a framework that emphasizes WAI-ARIA compliance and keyboard interaction across its widgets.
  • Syncfusion .NET MAUI Charts (part of Syncfusion Essential Studio Enterprise) is built on a platform supporting keyboard input, extendable to visual components in custom apps.

Discover Insights with Interactive Chart Zooming

January 16, 2026
Examine critical data points more closely, reducing visual complexity and enabling accurate trend analysis across even the most complex datasets.

Chart zooming allows users to interactively adjust the visible range of a chart to focus on specific data points, time periods, or value ranges for closer analysis. By enabling users to zoom in and out dynamically, it reduces visual clutter, improves clarity, and helps uncover trends, anomalies, or patterns that may be difficult to identify at a full-scale view. This interactive capability supports faster, more informed decision-making by allowing movement between high-level overviews and detailed insights without reloading data. Common use cases include analyzing financial performance over specific timeframes, investigating spikes or drops in operational metrics, reviewing detailed sensor or monitoring data, and highlighting key data segments during presentations or stakeholder reviews.

Several JavaScript chart controls support zooming including:

  • Highcharts Core lets you interactively zoom charts to explore dense datasets, isolate time ranges, and analyze trends with responsive controls.
  • KendoReact Charts (part of KendoReact by Telerik) allows you to zoom precisely, helping applications deliver clearer insights through focused data exploration.
  • AnyChart JS facilitates intuitive chart zooming, enabling users to examine detailed data segments while maintaining performance, flexibility, and visual clarity.
  • LightningChart JS lets you perform high-performance chart zooming for large-scale datasets, supporting real-time analysis with precision and responsiveness demands.

Compare Values Clearly with Range Charts

January 9, 2026
Gain financial insights with range area charts that visualize value bands between two data points, revealing price ranges, projections, and trends.

Range charts visualize financial data based on fixed price movements rather than time intervals, grouping activity into consistent ranges to highlight meaningful price action. By filtering out minor fluctuations and market noise, they make trends, volatility, support, and resistance levels easier to identify, especially in fast-moving or irregular markets. Common use cases include technical analysis for trading platforms, monitoring price volatility in equities or cryptocurrencies, and analyzing high-frequency financial data where understanding true market behavior is more important than tracking time-based changes.

Several React charting components provide you with range charts, including:

  • DevExtreme React Chart (part of DevExtreme Complete by Devexpress) lets you build financial range charts that emphasize price movement and support precise trend analysis.
  • amCharts 5: Charts facilitates creating interactive range charts that filter minor fluctuations and clearly expose underlying price trends effectively visually.
  • AnyChart JS lets you implement flexible range charts for financial dashboards, improving volatility analysis, pattern recognition, and decision-making accuracy speed.
  • Infragistics Ignite UI for React Chart (part of Infragistics Ignite UI) allows you to visualize range charts for volatile markets, revealing momentum and insights.
