複数の変数間の関係を強調表示

多次元チャートは、複数の指標または軸にわたるパターンと傾向を明らかにするため、複雑なデータ分析に最適

Multi-dimensional and relationship charts allow developers to present complex data structures and inter-variable relationships in a way that’s visually intuitive and analytically powerful. These chart types are essential for exploring correlations, comparing grouped metrics, and visualizing distributions across multiple dimensions. They are commonly used in statistical dashboards, performance analysis tools, and scientific applications where simple line or bar charts aren’t sufficient to capture the full context of the data.

Common charts include:

  • Combination Charts allow developers to overlay different chart types, such as bars, lines, and areas, within a single axis system, enabling comparison across metrics with varying scales or data types.
  • Radar & Polar Charts display multivariate data in a circular format, ideal for comparing values across categories that share a common center point, such as performance metrics or skill assessments.
  • Radial Chart formats extend circular visualization into more structured layouts, such as radial bar or radial line charts, providing a compact and distinctive way to show cyclical data or category-based trends.
  • Scatter & Bubble Charts plot data along two or three axes, often using the size of bubbles to represent an additional variable, making them ideal for visualizing trends, clusters, and outliers in high-volume datasets.

JavaScriptアプリにPDF変換を埋め込み

8月 27, 2025
PDFコンポーネントをJavaScriptアプリの変換サポートと統合すると、ユーザーはPDFと他のファイル形式の間でドキュメントを変換可能

JavaScript PDF components that support format conversion play a critical role in modern web and enterprise applications, allowing developers to programmatically generate, manipulate, and transform documents within the browser or on the server. These tools simplify workflows that require format interoperability, such as generating printable reports from web content, archiving dynamic documents, or extracting data for analysis. Their ability to convert between PDF and other widely used formats ensures compatibility across systems, supports digital transformation goals, and enhances document handling efficiency.

Common conversions include:

  • HTML to PDF: Render entire web pages or fragments into paginated PDF documents while preserving layout, styles, and interactive elements.
  • PDF to Excel: Extract tabular data from PDFs, converting it into XLS or XLSX files for data analysis or re-use in spreadsheet applications.
  • PDF to Image: Convert each page of a PDF into image formats such as PNG or JPEG, useful for previews, thumbnails, or annotations.
  • RTF to PDF: Convert Rich Text Format files into PDFs to preserve text styling and document structure in a widely accepted format.
  • PDF to PowerPoint: Convert PDF content into PPT or PPTX format, enabling slide-based presentation of document content.
  • PDF to SVG: Translate PDF pages into scalable vector graphics, ideal for embedding high-quality visuals in web pages.
  • Word to PDF: Transform DOC or DOCX files into PDFs, retaining formatting, tables, and images for standardized sharing and storage.

ReactアプリでQRコードとバーコードをレンダリング

8月 27, 2025
React UIスイートは、開発者が最小限の構成で形式、サイズ、シンボル、エクスポートオプションを調整できる堅牢なバーコードツールを含む

Barcode components in React UI suites deliver a easy way to integrate machine-readable encoding directly into modern web applications. These components offer a high-level interface for rendering both one-dimensional and two-dimensional barcodes, with customizable options for type (symbology), dimensions, styling, and export formats. They enable developers to choose between vector-based (SVG) or bitmap (Canvas) rendering, and often support direct exports to PNG, PDF, or SVG formats. Such features make barcodes a flexible integration point for inventory systems, shipping labels, ticketing, and other use cases requiring reliable, visual encoding of data within React environments.

Several React UI suites offer Barcode components including:

  • KendoReact by Telerik supports a wide range of one-dimensional (1D) symbologies as well as QR codes, configurable via props for size, color, border, and text.
  • Wijmo by MESCIUS provides React wrappers for numerous barcode controls, including Code128, Codabar, Code39, Ean8, Ean13, GS1-128, QR Code and UPC variants.
  • Syncfusion Essential Studio Enterprise offers React barcode generator components that support both 1D and 2D encoding, including Codabar, QR code, DataMatrix, and UPC-A.
  • jQWidgets includes both barcode and QR Code components among its widget set, making barcode generation available in its comprehensive suite of UI elements.

LightningChart JS v8.0では、よりスマートなデフォルト、柔軟な配置、強化されたカスタマイズを備えた、完全に刷新された凡例システムを導入

LightningChart JS is a high-performance JavaScript charting library that utilizes WebGL rendering and GPU acceleration to deliver exceptional performance for a wide range of data visualization needs. It is designed to handle large datasets and complex visualizations with ease, enabling developers to create interactive and visually appealing 2D and 3D charts. Ideal for applications demanding smooth real-time data updates, such as financial platforms, engineering tools, scientific research dashboards, and industrial monitoring systems, LightningChart JS provides a comprehensive API for customization and integration into web-based projects.

The LightningChart JS v8.0 update completely reworks legend functionality, making legends a property of the chart, removing visual obstructions, and improving adaptability to available space. The API configuration is now more intuitive and capable, with built-in options supporting a wider range of use cases. Plug‑in support also enables easy extension or customization of legend behavior. By default, legends now appear automatically beneath trends, reducing developer setup time, while still allowing you to manually create multiple legends when needed. You can position legends using built-in presets or define custom placements, and control click behavior using either the provided handlers or your own. When creating series, you can also exclude specific ones from appearing in legends, giving you fine-grained control over legend content.

To see a full list of what's new in v8.0, see our release notes.

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.

RTLサポートを使用したVue.jsでレポートを立案

8月 22, 2025
右から左へのレイアウトをサポートするレポートコントロールを使用すると、Vue.js開発者はレポートアプリケーションを装備してRTL言語を簡単に処理可能

RTL support (Right-to-Left) enables the creation and viewing of reports that can accommodate languages that are read from right to left, such as Arabic, Hebrew, Persian, Urdu, and so on. In the context of report design, this involves aligning text, tables, charts, and interface elements in a way that respects the natural reading direction of said languages, so that the report is displayed correctly for the target audience. Support for RTL languages is a key capability for developers and organizations operating in multilingual environments, ensuring users working in these languages can design, view, and interpret reports accurately and comfortably within the reporting application.

Several Vue.js reporting components include RTL support, including:

  • DevExpress Reporting offers Vue.js developers comprehensive report controls that support right-to-left layout alignment for RTL language environments.
  • ActiveReportsJS by MESCIUS lets you design and preview RTL-based reports with proper text alignment, layout orientation, and interactive viewing for RTL language users.
  • Stimulsoft Reports.JS also supports Vue.js as well as having built-in RTL rendering to ensure report content aligns as required for right-to-left languages.
