O SurveyJS v2.2.0 adiciona os tipos de perguntas Slider e Range Slider para coletar valores únicos ou intervalos de valores com entrada interativa baseada em arrastar.

SurveyJS is a family of extensible JavaScript libraries designed to help developers build robust form management systems fully integrated into their web applications. These libraries work seamlessly with any backend system and are fully compatible with modern JavaScript frameworks, including React, Angular, and Vue.

The SurveyJS 2.2.0 update introduces new Slider and Range Slider question types that enable developers to implement more interactive and precise input mechanisms within surveys. These components support a wide range of configuration options, including customizable minimum and maximum values, step sizes, labeled scales, and tooltip formatting. The Range Slider further enhances flexibility by allowing respondents to select and drag a value range using dual thumbs, with optional constraints on range length. Both question types can be seamlessly bound to text input fields, offering a more responsive and accessible data collection experience in custom survey workflows.

Visualize padrões de dados complexos em 3D

Analise relacionamentos complexos entre várias propriedades de dados com um gráfico de superfície, que permite uma visão mais profunda por meio de plotagem 3D.

A surface chart is a powerful data visualization tool used to represent three-dimensional data, where the relationships between three numerical variables are plotted across a surface. By mapping values on the X, Y, and Z axes, and optionally applying dynamic color gradients to introduce a fourth variable, surface charts reveal patterns and correlations not easily detected in 2D charts. This makes them particularly valuable in fields such as engineering, scientific research, and finance. The ability to interpret multiple data dimensions simultaneously enables clearer insights and supports more informed, data-driven decisions.

Several JavaScript chart controls offer Surface Charts including:

  • jChartFX Plus lets you create rich, interactive surface charts that visualize three-dimensional data relationships with customizable styling and dynamic behavior.
  • AnyChart JS allows you to render detailed surface charts with gradient coloring, revealing multidimensional data insights for web-based analytics applications.
  • LightningChart JS Trader facilitates ultra-fast rendering of high-performance surface charts, ideal for complex financial modeling and real-time data exploration.
  • TeeChart JS enables advanced surface chart plotting with full 3D rotation, color mapping, and interactive tools for scientific and engineering analysis.

Destaque instantaneamente os padrões de dados da grade

Use a formatação condicional para enfatizar automaticamente as principais métricas, ajudando a revelar tendências e anomalias em seus dados.

Conditional formatting in a grid refers to the dynamic application of visual styles—such as colors, icons, or font changes—to cells based on the values they contain or rules defined by the developer. This feature enables developers to visually differentiate data patterns, identify anomalies, or highlight critical values directly within a data grid without additional processing or user interaction. By presenting real-time visual cues tied to data content, conditional formatting enhances readability, supports quick analysis, and improves user decision-making, particularly in data-heavy applications where clarity and immediacy are essential.

Several Angular grid controls offer conditional formatting, including:

  • Wijmo FlexGrid (part of Wijmo by MESCIUS) enables rule-based styling for grid cells, providing real-time visual feedback that improves data interpretation.
  • Handsontable by Handsoncode allows you to define custom cell styling conditions, enabling immediate visual cues based on cell content or validation rules.
  • Ignite UI Angular Grid (part of Infragistics Ignite UI) facilitates the automatic formatting of cells, enhancing the visibility of key data.
  • Syncfusion Grid control for JavaScript (part of Syncfusion Essential Studio Enterprise) lets you apply dynamic conditional formatting rules to visually highlight data trends.
