データサマリーでレポート分析を強化

3月 10, 2025

Reactアプリケーションでレポートを生成するときに要約と集計を組み込むことにより、読者がデータを解釈および分析するのを支援

The ability to summarize and aggregate information in a report provides a means of condensing extensive data sets to form part of a concise and meaningful overview of the report's contents. This feature highlights key insights, eliminating the need for readers to sift through raw data. Aggregation processes the data mathematically through calculations such as totals, averages, percentages, means, or medians to identify patterns and trends. By highlighting and summarizing the report's findings in this way, this feature consolidates complex information in a way that aides the reader in identifying patterns and interpreting the data.

The following React reporting components support summaries and aggregates:

DevExpress Reporting gives users the ability to efficiently summarize and aggregate data to draw attention to key insights when generating reports in React applications.
ActiveReportsJS by MESCIUS includes React reporting tools that can equip web applications with data aggregation and summarization features for precise data analysis.
Stimulsoft Reports.JS also works with React and lets you create structured reports with advanced summary functions and aggregation tools for data-driven insights.

チャートでロケール対応フォーマットを実装

3月 10, 2025

Highcharts v12では、地域の日付と数値の書式設定を有効にするためにlang.localeが追加され、未定義の場合はブラウザの言語がデフォルトになります。

Highcharts is a JavaScript charting framework that allows web developers and data analysts to generate dynamic, visually appealing charts and graphs for websites and web applications. It can display a variety of chart types, including line, spline, area, column, bar, pie, scatter, and many more. Highcharts is well-known for its ease of use, rich documentation, and ability to handle huge datasets efficiently. Features include responsive design, accessibility support, and cross-browser compatibility. Its customization capabilities allow users to create bespoke data visualizations that increase engagement and provide insightful data presentations.

Highcharts v12 introduces the lang.locale option, enabling locale-aware formatting for dates and numbers in charts. This option allows you to define the locale for all charts on a page or set it individually per chart. If no locale is specified, the chart automatically defaults to the page’s or browser’s language settings. Utilizing the browser’s Intl object, lang.locale ensures that dates and numbers are formatted correctly, not only replacing elements like month and weekday names but also structuring entire date expressions according to the selected locale. For instance, American English (en-US) formats a date as January 1, 2025, while British English (en-GB) displays it as 1 January 2025.

To see a full list of what's new in v12, see our release notes.

Highcharts Core is licensed on an annual or perpetual basis, OEM licenses, and Advantage Renewals. It is licensed per Developer and has several license options including Internal, SaaS, SaaS+, and Self Hosted. See our Highcharts Core licensing page for full details.

テクニカル指標で予測を改善

3月 3, 2025

財務分析を強化し、トレンドの特定、モメンタムの測定、ボラティリティの分析、取引タイミングの最適化を行う高度な指標を提供

Indicators in a financial chart are mathematical formulas applied to market data, such as price and volume, to generate insights into trends, momentum, volatility, and trade opportunities. Indicators are visualized as lines, histograms, or overlays on the chart, providing dynamic analysis rather than static points. Moving averages track price trends with smooth lines, while oscillators like RSI appear as separate graphs to measure momentum. These tools help traders analyze patterns, confirm price movements, and support decision-making. For software developers, integrating indicators enhances data visualization, enables algorithmic trading strategies, and improves user experience by delivering clear, actionable insights.

Several Angular charting components provide support for indicators within financial charts, including:

Highcharts Stock by Highsoft lets you visualize financial indicators with dynamic charts, including trendlines, moving averages, and technical overlays.
Ignite UI for Angular Chart (part of Infragistics Ignite UI) enables real-time market analysis with built-in financial indicators, enhancing data-driven insights and decision-making.
Syncfusion JavaScript Chart (part of Syncfusion Essential Studio Enterprise) supports financial indicators for interactive analysis of trends, momentum, and volatility.

2月 28, 2025

グリッドコンポーネントを簡単に構成して、チェックボックスやドロップダウンなどの特殊なセルタイプを使用して、データをより直感的に表示して編集できます。

Cell types in Grid components are specialized configurations that define how data is displayed, edited, and interacted with within a grid or table structure. They allow developers to tailor the presentation and functionality of each cell to better match the type of data it contains. By specifying cell types such as text, numeric, date/time, and more, Grid components can provide intuitive controls and formatting automatically, streamlining data entry and reducing errors.

Common features include:

Button cells let users trigger actions directly within the grid, such as saving or deleting.
Checkbox cells provide aan intuitive way to select multiple items or toggle options.
Date/Time cells feature calendar pickers or time selectors to minimize entry errors.
Dropdown/List cells restrict user input to predefined options, ensuring data consistency.
Hyperlink cells enable navigation to resources or external links without leaving the grid.
Image cells support thumbnail previews, enhancing visual representation of content.
Numeric cells enforce number-only input, often with built-in validation.
Text/String cells are versatile for general data, supporting long or multiline input.
