인터랙티브 피벗 차트로 트렌드를 시각화하세요

12월 23, 2025
JavaScript UI 제품군의 피벗 차트 컴포넌트는 복잡한 데이터 시각화를 단순화하여 유연한 분석 기능을 제공합니다.

A pivot chart is a dynamic data visualization tool that works in conjunction with a pivot table to present summarized data in a graphical format. It allows users to interactively explore and analyze large datasets by adjusting dimensions such as categories, series, and filters without modifying the underlying data. By visually representing trends, comparisons, and patterns, pivot charts help users make data-driven decisions more efficiently. They are especially useful in business intelligence and reporting scenarios where clarity and flexibility in viewing aggregated data are essential.

Several JavaScript UI suites provide you with pivot chart functionality, including:

  • DevExtreme Complete lets you integrate pivot‑style data summarization with interactive charts where grid data drives visual analytics in JavaScript apps.
  • Wijmo by MESCIUS lets you bind its OLAP and PivotChart controls so pivot‑engine summaries feed FlexChart visuals that display the selected aggregated values.
  • SmartClient by Isomorphic Software lets you visualize multi‑dimensional pivot data with its chart components, enabling dynamic pivoting and summary chart updates.
  • Syncfusion Essential Studio Enterprise allows developers to display aggregated pivot table results in interactive pivot charts with multiple types, drill‑down, and customization.

JavaScript 애플리케이션에서 직관적인 라디오 그룹 컨트롤을 사용하여, 미리 정의된 데이터 세트에서 하나의 값을 선택할 수 있는 기능을 구현하세요.

A radio group in data editing refers to a set of mutually exclusive options presented as selectable buttons, where only one option can be active at a time. It is typically used in user interfaces to enforce a single selection from a predefined set of values, which helps reduce input errors and ensures data consistency. By visually grouping related choices and clearly indicating the selected value, a radio group simplifies decision-making for users and speeds up data entry. This control is especially useful in forms and configuration settings where a user must choose one valid option from several possibilities.

Several JavaScript data editor collections provide support for radio groups, including:

  • DevExtreme Angular Data Editors (part of DevExtreme Complete by DevExpress) lets you create radio groups with custom layouts, dynamic data binding, and intuitive selection.
  • KendoReact Data Editors (part of KendoReact by Telerik) provides fully accessible radio group components with flexible styling options and easy integration into React apps.
  • Infragistics Ignite UI for Angular Data Editors (part of Infragistics Ignite UI) offers configurable radio group functionality with straight-forward data mapping.
  • Syncfusion JavaScript Data Editors (part of Syncfusion Essential Studio Enterprise) includes customizable radio group controls for smooth interaction across major web frameworks.

SpreadJS 19는 새로운 서버 애드온을 통해 공동 작업을 지원합니다. 여러 사용자가 하나의 스프레드시트를 동시에 편집할 수 있습니다.

SpreadJS is a JavaScript spreadsheet and data visualization component built to deliver Excel-compatible functionality within web applications. It provides a flexible, high-performance interface for displaying and manipulating tabular data, supporting advanced features such as formulas, pivot tables, charts, conditional formatting, and data binding. SpreadJS integrates smoothly with popular frameworks like React, Angular, and Vue, and includes robust import and export capabilities for Microsoft Excel files. It is commonly used in enterprise applications where users need a responsive, interactive spreadsheet experience directly in the browser.

The SpreadJS 19.0.0 update introduces a new Collaboration Server Add‑on that enables real‑time, multi‑user editing of the same spreadsheet within web applications by integrating the collaboration framework and server infrastructure directly into SpreadJS. This add‑on lets developers build functionality where multiple clients see and apply changes instantly to workbook data with consistent state across users, supports conflict‑free concurrent edits using Operational Transformation logic, and includes features such as live user presence and permission controls.

To see a full list of what's new in 19.0.0, see our release notes.

SpreadJS is licensed per developer and includes 1 Year Maintenance (major and minor version releases and unlimited support phone calls). SpreadJS requires an Annual or Perpetual Deployment License. The optional Add-ons are available at an additional cost, and require a SpreadJS license. See our SpreadJS licensing page for full details.

간결한 불릿 차트(bullet chart)로 예산, 예측, 실제 값을 비교하여 변동 사항을 즉시 발견하고, 목표 달성을 위한 진행 상황을 명확히 추적하세요.

Bullet charts are goal-oriented visualizations that compare actual performance against targets and benchmarks such as budget and forecast values in a single, easy-to-read view. They offer a clear alternative to gauges and meters by showing progress toward goals while making variances and shortfalls immediately obvious. By presenting multiple reference points together, bullet charts help stakeholders interpret performance quickly and consistently across metrics. Common use cases include financial reporting, sales and margin tracking, KPI dashboards, operational scorecards, and executive summaries where fast, reliable comparisons support better decision-making.

Several JavaScript chart controls offer bullet chart support including:

  • Highcharts Core by Highsoft lets you build bullet charts comparing performance against targets with interactive tooltips, responsive layouts, and customization.
  • KendoReact Charts (part of KendoReact by Telerik) allows you to render bullet charts, emphasizing KPIs, qualitative ranges, and accessibility-friendly components.
  • amCharts 5: Charts facilitates modern bullet charts with animated transitions, flexible axes, precise benchmarks, and theming for data-driven dashboards applications.
  • Syncfusion JavaScript Charts (part of Syncfusion Essential Studio Enterprise) lets you create bullet charts showcasing targets, ranges, and actuals.

사용자가 보는 부분만 렌더링하여 속도를 극대화하고, 메모리 사용량을 줄이며, 어떤 규모에서도 그리드 조작을 원활하게 유지하세요.

Virtual scroll support in a grid component is a rendering strategy that displays only the rows and columns currently visible in the viewport while dynamically loading and unloading data as the user scrolls. It minimizes DOM size and memory usage by avoiding the creation of off-screen elements, which improves rendering speed, reduces layout thrashing, and maintains smooth interaction even with very large datasets. This approach enables grids to handle millions of records efficiently without requiring pagination, lowers CPU and GPU load, and delivers consistent performance across a wide range of devices.

Several React grid controls offer virtual scroll capability including:

  • DevExtreme React Data Grid (part of DevExtreme Complete by DevExpress) lets you render only visible records offering excellent performance for displaying thousands of data rows.
  • KendoReact Data Grid (part of KendoReact by Telerik) allows you to virtualize grid content for rapid scrolling and reduced DOM overhead with large datasets.
  • Wijmo React DataGrid (FlexGrid) (part of Wijmo by MESCIUS) facilitates virtual scrolling that loads data on demand, minimizing rendering work and preserving fluid navigation.
  • Infragistics Ignite UI for React Data Grid (part of Infragistics Ignite UI) enables row and column virtualization to significantly boost performance for large datasets.
