遵守 WCAG 標準，並透過直觀的 JavaScript 圖表提供清晰、可訪問的資訊。

WCAG (Web Content Accessibility Guidelines) compliance in JavaScript charts ensures that visual data representations are accessible to all users, including those with disabilities. This involves implementing features such as semantic markup for assistive technologies, keyboard navigation support, high-contrast color schemes for users with visual impairments, and descriptive alternative text for charts and data points. Additionally, it may include providing data tables or summaries as textual alternatives and ensuring that interactive elements are operable without reliance on a mouse. Achieving WCAG 2.0 compliance enhances usability, meets legal accessibility standards, and promotes inclusive user experiences across web applications.

Several JavaScript chart controls offer WCAG compliance including:

  • Highcharts by Highsoft includes an accessibility module with keyboard navigation, screen reader compatibility, high-contrast themes, and support for voice input and sonification.
  • DevExtreme Chart (part of DevExtreme Complete by DevExpress) provides features like keyboard navigation, screen reader support, and high-contrast themes.
  • Kendo UI for Angular Chart (part of Kendo UI by Telerik) incorporates features such as keyboard navigation, semantic HTML output, and screen reader compatibility.
  • amCharts: Charts library includes keyboard navigation, high-contrast display modes, and text-based data alternatives to enhance accessibility.

讓使用者能夠在保留內容和樣式的同時，直接在 JavaScript Web 應用程式中將試算表匯出為 PDF 檔。

Exporting a spreadsheet to PDF from a JavaScript application is a widely used feature that allows users to generate portable, print-ready documents directly from the browser. It converts the contents of a spreadsheet, such as cell data, formulas, formatting, charts, and images into a Portable Document Format (PDF) file. This capability ensures that the data, formatting, and layout from the original spreadsheet are preserved without relying on external applications or manual intervention. It is particularly useful for generating reports, invoices, or records that need to be shared, printed, or archived in a fixed format. By enabling PDF generation directly within the web application, developers can offer users a straightforward method to archive, print, or share spreadsheet content in a consistent and professional format across devices and platforms.

Several JavaScript spreadsheet components allow you to export to PDF, including:

  • SpreadJS by MESCIUS enables users to convert complex spreadsheet content, including formulas and styling, directly to PDF within a JavaScript application.
  • Telerik Spreadsheet jQuery (part of Kendo UI) provides an integrated PDF export option that retains the structure and styling of the spreadsheet for uniform document output.
  • Jspreadsheet Pro, through the export to PDF extension, facilitates the export of spreadsheet content to PDF, ensuring the integrity of the original document.
  • Syncfusion Spreadsheet JavaScript (part of Syncfusion Essential Studio Enterprise) allows you to save spreadsheet documents as PDF files, preserving layout and style.

React 網格元件中的聚合功能允許使用者直接在網格介面中快速查看關鍵指標，如總和和平均值。

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.

在報表中整合圖表可將原始資料轉換為清晰、引人入勝的視覺物件，其可突出關鍵指標，以做出更明智的決策。

Charts in reports are graphical representations of data such as bar graphs, line charts and pie diagrams that are incorporated into business documents to illustrate key insights and trends at a glance. By converting numbers into intuitive visuals, charts improve clarity and make comparisons between categories or time periods effortless while drawing attention to critical metrics like sales growth, customer churn or budget variances. These visual tools streamline data interpretation, empower stakeholders to make faster more informed decisions, foster alignment across departments and tell a cohesive data driven story without wading through rows of figures.

Several Vue.js reporting components support charts including:

  • Stimulsoft Reports.JS allows you to embed interactive charts in web reports, supporting diverse chart types, customization, and real-time data updates.
  • ActiveReportsJS lets you design dynamic chart components with extensive data bindings, responsive layouts, and export options for high-quality report visuals.
  • DevExpress Reporting facilitates integration of charts into interactive dashboards, offering cross-platform rendering, data analytics features, and customizable styling controls.
