用多级数据图表展示复杂性

7月 14, 2025
通过清晰的径向布局发现交互式多级数据中的模式、比例和关系，使层次结构易于探索。

Radial charts are circular data visualizations used to represent hierarchical, proportional, or cyclical data. A key type is the sunburst chart, which displays multi-level hierarchies using concentric rings, where each ring represents a level and each segment shows a category or subcategory. This format helps users quickly grasp both structure and proportion. Sunburst charts are ideal for exploring complex data in a compact space and are commonly used for visualizing organizational charts, file systems, website structures, and product categories. Their interactive format allows users to drill into data for deeper insight without losing context.

Several JavaScript charting components provide you with radial charts, including:

  • amCharts 5: Charts lets you visualize hierarchical relationships with radial charts, including detailed, interactive sunburst charts for deep data exploration.
  • Sencha Ext JS Chart (part of Sencha Ext JS) enables elegant radial chart rendering, including sunburst charts that clearly reveal layered structures and category breakdowns.
  • FusionCharts Suite XT provides interactive radial chart options like sunburst charts, ideal for comparing multi-level data with visual precision and clarity.
  • Syncfusion JavaScript Chart part of (Syncfusion Essential Studio Enterprise) facilitates powerful radial data displays, using sunburst charts to uncover nested patterns.

将 Image Capture 功能添加到打印工作流程

JSPrintManager 8.0 现在允许客户端设备使用摄像头捕获快照，从而增强文档处理和打印的输入选项。

Neodynamic offers two JSPrintManager solutions for client-side printing and scanning in web applications. JSPrintManager for Any Web Platform allows you to integrate printing functionality into any website built with technologies like ASP.NET, PHP, or Blazor using pure JavaScript. Neodynamic also offers JSPrintManager for Blazor which enables you to seamlessly add printing capabilities to your Blazor server or WebAssembly projects with C# code. Both solutions empower you to print various data formats directly from the browser without requiring user interaction with print dialogs.

The Neodynamic JSPrintManager 8.0 releases add the ability for the Windows Client to take a video snapshot through any video device available on the client PC. This means, for example, that a camera can be used as a scanner to take a snapshot/picture. This is particularly useful in contexts where quick documentation is needed, such as capturing IDs, receipts, or physical documents, without needing a separate scanning application. It reduces reliance on traditional scanners and broadens the type of input devices that can integrate with browser-based printing operations.

To see a full list of what's new in 8.0, see our release notes for JSPrintManager for Any Web Platform and JSPrintManager for Blazor.

Neodynamic JSPrintManager is licensed per Web App and Web server and is available as a Perpetual license which includes 1 year of free updates and priority support. See our Neodynamic JSPrintManager for Any Web Platform and Neodynamic JSPrintManager for Blazor licensing pages for full details.
