Exporte gráficos para PDF em jQuery

Abril 28, 2026
Ative a visualização de dados com recursos de exportação de PDF em jQuery, permitindo que os usuários distribuam gráficos como arquivos PDF diretamente do navegador facilmente.

Exporting charts to PDF involves generating a static, portable document version of a chart that preserves its visual structure and data representation. This capability is valuable for reporting, compliance, and sharing insights in a consistent format that does not depend on a live application or browser environment. It allows teams to distribute visual data in a widely accepted file format, ensures layout stability across devices, and supports archival or print-ready use cases without requiring additional tooling.

Several jQuery chart components allow you to export to PDF, including:

  • DevExtreme jQuery Chart (part of DevExtreme Complete by DevExpress) lets you export charts to PDF with customizable layouts, preserving fidelity, annotations, and data clarity.
  • Kendo UI jQuery Charts (part of Kendo UI by Telerik) provides built-in chart export to PDF through its drawing API for direct browser-based document generation.
  • FusionCharts Suite XT includes native PDF export capabilities for charts, supporting both client-side generation and server-side services for flexible deployment.
  • jQWidgets Chart (part of jQWidgets) offers a dedicated saveAsPDF method within its API, enabling the direct export of chart content to PDF with optional server-side handling.

Exiba hierarquias como listas recuadas

Abril 24, 2026
O OrgChart JS oferece um layout de lista em árvore que apresenta dados hierárquicos em uma estrutura alinhada verticalmente, facilitando a leitura das informações aninhadas.

OrgChart JS by BALKAN App is a JavaScript library designed for creating flexible, interactive and customizable organizational charts for presenting structural data. This visual tool helps managers illustrate the roles and hierarchy of an organization, supporting a variety of features, including grouping, assistant nodes, expand/collapse, a built-in search field, and multi-format exports for example to PDF, PNG, SVG or CSV. Compatible with all modern browsers, it supports thousands of nodes without any impact on performance, and offers extensive customization, giving users a versatile and efficient tool for visualizing hierarchical data structures in web applications.

OrgChart JS includes the Tree List Layout, offering a space-efficient and readable way to represent hierarchical data by combining a tree structure with a linear list, enabling developers to display deeply nested hierarchies without the horizontal sprawl of traditional node-link diagrams. It allows nodes to be expanded and collapsed within a vertically aligned list, improving navigation and scalability while maintaining parent-child relationships, and supporting extensive nesting without compromising usability. This makes it particularly useful in scenarios with limited screen space or large datasets, where reducing visual complexity while preserving the full hierarchy is essential, such as administrative dashboards and data management interfaces.

OrgChart JS is licensed based on usage, offering single website, unlimited websites or SaaS, and OEM licenses. It is available as a perpetual license with 1 year maintenance and technical support. See our OrgChart JS licensing page for full details.

Use o ActiveReportsJS para criar relatórios mestres ricos em detalhes que exibem claramente dados relacionados e hierárquicos.

ActiveReportsJS is a powerful, lightweight reporting tool designed to integrate advanced reporting capabilities into any JavaScript application. ActiveReportsJS enables developers to create, view, export, and print richly formatted reports entirely on the client side - with zero server dependencies.

In this blog post, MESCIUS Product Consultant Victor Stahlman demonstrates how to build nested data regions in ActiveReportsJS to create master-detail reports that display related data, such as customers and their orders, within a structured layout. He walks your through configuring datasets, nesting controls like Lists and Tables, and applying filters to correctly link and present hierarchical data relationships in your reports. Key topics include:

  • Growth vs. Static Data Regions
  • Understanding the Master-Detail Concept
  • Choosing the Report Type
  • Building the Report Structure

By implementing nested data regions in ActiveReportsJS, you can transform flat datasets into structured, master-detail reports that are easier to read and analyze.

Read the complete blog to get started building scalable, dynamic JavaScript reports that deliver more meaningful insights to your users.

Construa formulários precisos com validação JSON Schema

Abril 24, 2026
O Optimajet FormEngine permite validação e autopreenchimento em tempo real do IDE, ajudando você a detectar problemas antecipadamente e melhorar o desenvolvimento de formulários.

Optimajet FormEngine is a drag-and-drop React form builder that lets teams create, manage, and render complex web forms without writing frontend code. It allows developers and business users to visually design forms, store them as JSON, and render them at runtime. As a React JS library, it easily integrates into existing applications while giving developers full control over form logic, structure, and data flow, making it well suited for complex data collection.

Optimajet FormEngine enables JSON Schema validation for forms, allowing developers to validate form JSON directly within their IDE, identify structural issues, incorrect data types, and unsupported configurations early in the development process, and enforce a consistent, well-defined structure across all forms. By providing real-time feedback, inline error highlighting, and autocomplete suggestions, it improves accuracy and reduces the need for repeated testing cycles, helping developers work more efficiently while minimizing runtime errors and ensuring more reliable form implementations.

Optimajet FormEngine is licensed based on usage type (internal commercial use, public web/SaaS, or OEM embedding), number of domains for the visual editor, and access to additional ready-made components. Licenses are perpetual and include 6 months or 1 year of updates and support. See our Optimajet FormEngine licensing page for full details.

Aprimore visualizações de dados Vue.js incorporando anotações dinâmicas que destacam os principais insights e apoiam análises interativas.

Annotation support in a Vue.js chart component refers to the capability to overlay additional contextual elements, such as labels, markers, lines, or regions, directly onto a chart to highlight specific data points, thresholds, or events. This feature enables developers to enrich visualizations with meaningful insights without altering the underlying dataset, making it easier to communicate key information such as trends, anomalies, or business rules within the UI.

Several Vue.js chart components support chart annotations, including:

  • Wijmo Vue Chart (FlexChart) (part of Wijmo by MESCIUS) lets you add configurable chart annotations that highlight data points, thresholds, and ranges.
  • DevExtreme Vue Chart (part of DevExtreme Complete by DevExpress) allows you to incorporate annotation layers into charts, supporting labels, shapes, and guides.
  • Highcharts Core by Highsoft facilitates advanced chart annotations with flexible positioning, rich styling, and event handling.
  • Kendo UI Vue Charts (part of Kendo UI Vue Charts by Telerik) enables annotation features within charts that visually emphasize key data elements.
