Visualizza enormi set di dati senza ritardi

Giugno 3, 2025
NOV Chart for .NET 2025.1 aggiunge le serie Fast Bar, Fast Line e Fast Point accelerate da GPU per eseguire il rendering di milioni di punti dati in tempo reale.

NOV Chart for .NET by Nevron is a comprehensive .NET charting component suite designed for cross-platform application development. It offers an array of 2D and 3D chart types, along with smart data labeling, an advanced chart axes model, numerous interactivity features and GPU-accelerated real-time rendering based on OpenGL. This library allows developers to seamlessly integrate rich, dynamic and interactive business, scientific, financial and presentation data visualizations into their .NET applications for more effective communication.

The NOV Chart for .NET 2025.1 update introduces Fast Bar, Fast Line, and Fast Point series that leverage GPU acceleration to deliver real-time visualization of extremely large datasets, enabling developers to render millions of data points with minimal latency in both 2D and 3D contexts and apply per-point color information for detailed analysis. By offloading heavy rendering tasks to the GPU, these new series reduce CPU overhead and free resources for other application logic, making them particularly valuable in scientific, engineering, and medical scenarios where high-throughput data streams must be displayed without delay.

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.

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.

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.
  • amCharts 5: Charts library includes keyboard navigation, high-contrast display modes, and text-based data alternatives to enhance accessibility.

Accedi ai dati dei grafici in tempo reale tramite le API JavaScript

Maggio 22, 2025
I controlli grafici React possono recuperare dati aggiornati su richiesta, integrandosi con API JavaScript personalizzate per visualizzazioni visive dinamiche.

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.

Correggi il posizionamento delle descrizioni comando dei grafici senza codice personalizzato

Maggio 15, 2025
Highcharts 12.2 introduce un modo dichiarativo per controllare il posizionamento delle descrizioni comando, eliminando la necessità di regolazioni manuali di JavaScript.

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.

The Highcharts v12.2.0 release introduces a new Tooltip Positioning capability that lets you control tooltip placement directly through configuration, without writing any custom JavaScript. With the new tooltip.fixed and tooltip.position options, you can easily set fixed positions for tooltips and define exactly where they should appear on the chart. This enhancement simplifies layout management, reduces implementation time, and ensures a cleaner, more consistent user experience across your data visualizations.
