Highcharts Grid 通过智能行虚拟化提供海量数据的流畅、高性能渲染。

Highcharts Grid is a feature-rich data grid component developed by Highsoft, designed for use within Highcharts Dashboards or as a standalone component. Grid Lite is a free, lightweight version ideal for developers seeking a performant and accessible data grid with a basic feature set. Grid Pro is a commercial, feature-rich version built for complex applications that demand advanced data manipulation and interactivity. It includes all the capabilities of Grid Lite, along with a highly customizable and interactive interface that supports inline editing, column sorting, and event handling, enabling developers to build responsive data visualization applications.

Highcharts Grid delivers high performance when handling large datasets by employing row virtualization, a technique that renders only the rows currently visible within the viewport. This significantly reduces memory consumption and ensures fluid, responsive scrolling, even when working with thousands of records.

Highcharts Grid Pro requires a license for Highcharts Dashboards, licensed per developer as an Annual or Perpetual License with Internal, Saas, SaaS+ and OEM distribution options. The annual license includes support and all product updates for 1 year and must be renewed to continue to use the software. The perpetual license includes an "Advantage Subscription" for 1 to 5 years which provides support and updates for that period. If you do not renew Advantage then you may continue to use the software at the last release available during the active Advantage period. See our Highcharts Dashboards licensing page for full details.

以节省空间的方式可视化数据

径向图提供了一种引人注目的方式来显示比较或周期数据，将标准表示形式转换为引人入胜的圆形视觉对象。

Radial charts provide an intuitive way to visualize hierarchical and categorical data. They display bars on a polar coordinate system instead of a cartesian system, which uses an x-y grid for positioning data. These charts represent values in a circular layout, making it ideal for comparing proportions and relationships between data points. Circular bar charts, a variation of the traditional bar chart, arrange data in a radial format for displaying comparisons between categories. They are particularly useful for visualizing periodic or cyclical data, such as time-based metrics. Sunburst charts break down hierarchical structures into concentric rings. The center of the chart typically represents the root category, while outer rings depict subcategories. These are used for visualizing part-to-whole relationships within a dataset.

Several React chart controls offer radial charts including:

  • DevExtreme Chart (part of DevExtreme Complete by DevExpress) enables developers to render concentric segments with gradient fills, animation effects, and interactive tooltips.
  • Highcharts Core by Highsoft enables the creation of radial bar charts facilitating the display of data in a circular layout with bars extending outward from the center.
  • Wijmo FlexChart and FinancialChart (part of Wijmo by MESCIUS) offers radial bar chart support enabling developers to build compact, circular metric displays.
  • Ignite UI for React Chart (part of Infragistics Ignite UI) includes a radial bar chart type within its polar chart suite, optimized for performance and rendering quality.

Stimulsoft Reports.JS 2025.2.1 允许开发人员跨多个条形码符号对大型结构化数据进行编码，而不会牺牲布局或清晰度。

Stimulsoft Reports.JS provides a robust reporting toolkit designed specifically for JavaScript applications. This library leverages a client-side architecture, offering a pure JavaScript report engine for efficient report rendering directly within web browsers. The solution includes a user-friendly report designer for building reports with various data sources and visualizations, along with a report viewer for seamless integration and display within your JavaScript applications. This eliminates the need for server-side dependencies or browser plugins, simplifying the development process for embedding powerful reporting functionalities into your web projects.

The Stimulsoft Reports.JS 2025.2.1 update introduces support for the Macro PDF417 barcode, allowing developers to handle larger data payloads within reports. Unlike the standard PDF417 barcode, which is limited in data capacity, the Macro PDF417 format enables the encoding of large data files by splitting them into multiple linked symbols. This enhancement is particularly useful when working with high-volume or multi-page reports, providing a reliable solution for encoding structured data without compromising layout or readability.

To see a full list of what's new in 2025.2.1, see our release notes.

Stimulsoft Reports.JS is licensed per developer and is available as a Perpetual license with 1 year support and maintenance. See our Stimulsoft Reports.JS licensing page for full details.
