Velocizza l'inserimento dei dati e riduci gli errori

Giugno 3, 2025
Il completamento automatico fornisce agli utenti una guida all'input in tempo reale per ridurre gli errori e migliorare l'efficienza.

Autocomplete is a feature that dynamically suggests valid inputs as the user types, based on the current context or previously entered values. It enhances productivity by reducing the amount of typing needed and helps prevent errors or invalid entries by guiding users towards acceptable inputs. Ultimately, it enhances the overall user experience by making interfaces more intuitive and efficient for both technical and non-technical users.

Several Angular data editor collections include autocomplete features, such as:

  • DevExtreme Complete Data Editors (part of DevExtreme Complete) lets you enhance text input with real-time suggestions, supporting custom templates and several data sources.
  • Kendo UI for Angular Data Editors (part of Kendo UI) allows you to provide users with dynamic suggestions, supporting multiple selections and customizable templates.
  • Wijmo Input and Editors (part of Wijmo by MESCIUS) lets you implement autocomplete with filtered suggestions based on user input.
  • jQWidgets Data Editors (part of jQWidgets) enables autocomplete in input fields, displaying a dropdown of matching items to assist users in making accurate selections.

Aggiungi precisione ai dati basati sul tempo

Giugno 2, 2025
LightningChart JS v7.1 offre una precisione a livello di nanosecondi ai grafici basati sul tempo, consentendo un'analisi estremamente dettagliata di dati temporali ad alta frequenza.

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.

To see a full list of what's new in v7.1, 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.

Le funzionalità di esportazione e stampa offrono agli utenti il pieno controllo sul modo in cui i report vengono condivisi, archiviati e riutilizzati su piattaforme e formati diversi.

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.

Garantisci l'accessibilità e la chiarezza dei dati per tutti gli utenti

Giugno 2, 2025
Rispetta gli standard WCAG e fornisci informazioni chiare e accessibili attraverso grafici JavaScript intuitivi.

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.

Genera PDF dai dati dei foglio di calcolo

Maggio 30, 2025
Consenti agli utenti di esportare fogli di calcolo in file PDF direttamente all'interno di un'applicazione Web JavaScript, mantenendo il contenuto e lo stile originali.

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.
