時間ベースのデータに精度を追加

6月 2, 2025
LightningChart JS v7.1は、時間ベースのチャートにナノ秒レベルの精度をもたらし、高頻度の時間データの超詳細な分析を可能に

LightningChart JS is a JavaScript/TypeScript library developed by LightningChart that is particularly well-suited for data-intensive visualizations, offering exceptionally fast rendering capabilities thanks to its use of WebGL. This makes it a strong choice for applications that require real-time data updates, such as financial platforms, engineering tools, scientific research dashboards, and industrial monitoring systems. It provides high-performance, 2D, 3D, and real-time charting controls and a comprehensive suite of visualizations including candlestick, bar, line, and various technical indicators and drawing tools. This library enables software developers to craft interactive technical analysis tools without the need for server-side setup as it runs completely on the client device.

The LightningChart JS v7.1 update enhances its Date-Time axis capabilities by introducing support for nanosecond-resolution timestamps, allowing users to zoom into microsecond and nanosecond ranges for more granular time-based data analysis—well beyond the previous millisecond limitations. To utilize this feature, timestamps should generally be supplied as BigInt64. This update positions LightningChart JS among the few web charting libraries explicitly supporting nanosecond precision, making it a strong choice for applications requiring high-resolution temporal data visualization.

LightningChart JS is licensed per developer and is available as an annual license with 1 year support. See our LightningChart JS licensing page for full details.

エクスポート機能と印刷機能により、ユーザーはプラットフォームや形式間でレポートを共有、保存、再利用する方法を完全に制御可能

Exporting and printing functionality in reporting components is a core requirement for many software applications, particularly those used in business, finance, and analytics. These capabilities enable users to transform dynamic, on-screen reports into portable or hard-copy formats suitable for distribution, archiving, or further processing. High-performance reporting tools offer flexible export and print options to accommodate various workflows, whether for regulatory compliance, client communications, or internal documentation. Support for a broad range of output formats ensures that users can interact with report content in the way that best suits their needs.

Common features include:

  • Exporting to CSV supports tabular data extraction, commonly used in data exchange and processing pipelines.
  • Exporting to DOCX allows reports to be opened and edited in Microsoft Word, preserving text formatting and layout.
  • Exporting to HTML transforms reports into web-friendly formats, suitable for browser-based viewing or embedding.
  • Exporting to Images captures reports as static visuals for use in presentations or documentation.
  • Exporting to PDF generates fixed-layout files ideal for sharing and preserving report fidelity across platforms.
  • Exporting to PDF with AcroForms enables the inclusion of interactive form fields within PDFs, supporting user input and data capture.
  • Exporting to RTF offers a more lightweight editable format that retains essential formatting for basic word processing applications.
  • Exporting to TXT simplifies reports to plain text for lightweight use cases or system integration.
  • Exporting to XLS/XLSX provides spreadsheet-compatible outputs for further analysis and manipulation in Microsoft Excel.
  • Printing capabilities allow for high-quality, configurable physical output, often with options to manage pagination, headers, footers, and printer-specific settings.

Reactグリッドコンポーネントの集約機能を使用すると、ユーザーは合計や平均などの主要なメトリクスをグリッドインターフェイス内で直接すばやく表示可能

Aggregation in grid components allows users to automatically compute and display summary values, such as totals, averages, minimums, and maximums, across rows or columns of data. This feature enhances the analytical capability of a data grid by offering quick insights directly within the interface, reducing the need to export data for external processing. It is particularly valuable in business intelligence dashboards, financial applications, and administrative tools where on-the-fly data synthesis is essential.

Several React grid controls offer aggregation including:

  • Handsontable provides built-in support for column summaries, enabling functions like sum, min, max, and average to be easily configured per column.
  • SmartClient Grid by Isomorphic Software provides advanced summary capabilities via its GridSummaryRow feature, which supports configurable summary functions at both column and group levels.
  • Jspreadsheet Pro Data Grid includes a "footers" feature that allows for dynamic aggregation calculations using built-in or custom-defined functions, directly visible beneath the dataset.
  • ZingGrid supports data aggregation through its summary cell attributes, making it easy to apply functions such as sum, count, and average without additional scripting.

JavaScript APIを使用してライブグラフデータにアクセス

Reactグラフコントロールは、動的なビジュアル表示のためのカスタムJavaScript APIと統合することで、オンデマンドで最新のデータを取得可能

JavaScript API as a data source in React JavaScript Charts refers to the use of custom JavaScript functions or services that fetch and supply data dynamically to chart components at runtime, rather than relying on static datasets. This approach enables charts to reflect real-time data changes, support asynchronous operations, and integrate with external APIs or internal services. It is particularly useful for applications that require up-to-date information, such as dashboards, monitoring tools, or analytics platforms. The key advantage is enhanced flexibility and responsiveness, allowing developers to handle complex data flows, perform live updates, and tailor chart behavior based on interactive or conditional logic.

Several React Chart Controls offer support for using JavaScript API as a data source including:

  • Highcharts Core lets you populate charts with live data through JavaScript APIs, enabling dynamic updates and real-time visualization scenarios.
  • DevExtreme Chart (part of DevExtreme Complete by DevExpress) allows you to bind chart components to JavaScript API-driven data sources.
  • LightningChart JS facilitates high-speed rendering of data streamed from JavaScript APIs, ideal for intensive, real-time analytical dashboards.
  • ZingChart supports flexible data injection via JavaScript APIs, making it easy to refresh charts dynamically based on changing external datasets.
