ReactでグラフをSVGにエクスポート

1月 10, 2024
SVG形式にグラフをエクスポートする機能をアプリケーションに提供することで、ユーザーに柔軟性を提供

Exporting charts to SVG (Scalable Vector Graphics) format is vital for maintaining high-quality visuals in digital formats. SVGs are resolution-independent, meaning they retain their quality at any size, which is crucial for presentations or reports that might be viewed on different devices. This feature allows users to share their charts outside the chart creation tool while ensuring visual fidelity and sharpness.

Several React chart controls offer support for exporting to SVG including:

  • Highcharts Core is a lightweight, pure JavaScript library for interactive charts with extensive SVG export options.
  • KendoReact Chart provides declarative React charts with data-driven API and built-in SVG export for seamless integration in any React project.
  • Syncfusion JavaScript Chart is a feature-rich chart library with an intuitive API and flexible SVG export support for interactive visualizations and customizability.
  • FusionCharts Suite XT is a comprehensive charting platform with powerful SVG export tools and pre-built templates for rapid development and easy integration.

RESTful APIを使用したJavaScriptグリッドへのライブデータの取り込み

1月 9, 2024
グリッドをRESTful APIに接続してデータを取得し、アプリケーションのパフォーマンス、拡張性、保守性、使いやすさを向上させます。

A RESTful API is a standardized interface that facilitates interaction between your application and remote data sources. Built on the principles of Representational State Transfer (REST), it leverages familiar HTTP verbs like GET, POST, PUT, and DELETE to perform CRUD operations (Create, Read, Update, Delete) on resources. This elegant and widely adopted approach ensures predictable communication, simplifies data access and manipulation, and empowers your applications to be dynamic, scalable, and efficient. In essence, RESTful APIs act as secure intermediaries, orchestrating a seamless flow of information between your application and the data it needs.

Several JavaScript grid controls support RESTful as a data source, such as:

  • Syncfusion Grid control for JavaScript (part of Syncfusion Essential Studio Enterprise) is a feature-rich datagrid that supports seamless RESTful data binding.
  • Ignite UI Angular Grid (part of Infragistics Ignite UI) is an Angular-native grid, that can deal with unlimited rows and columns of data, with support for REST API data sources.
  • Sencha Ext JS Grid (part of Sencha Ext JS) is a customizable grid capable of processing large data sets, with support for local or remote data sources through RESTful methods.
  • SmartClient Grid (part of SmartClient by Isomorphic Software) is an enterprise-grade grid featuring robust REST integration, supporting custom filtering logic and real-time updates.
  • ZingGrid is a JavaScript library for building customizable data tables, which also offers REST data binding capabilities, for smooth scrolling and fast rendering with massive datasets.

グリッドデータをスクロールする際のコンテキストの維持

1月 4, 2024
列ヘッダをグリッドの上部に固定することで、大規模なデータセットで作業する際のユーザーエクスペリエンスを向上

Fixed headers are a user interface element found in grids, particularly those managing large datasets. They comprise the top section of the grid, typically encompassing the row containing column labels and potentially additional rows with key information. Unlike the scrollable body of the grid, these headers remain anchored to the viewport, acting as a persistent reference point while users navigate through the data, thus improving user experience.

Several React grids support fixed headers including:

  • KendoReact Data Grid (part of KendoReact by Telerik) includes fixed headers that stay visible as you scroll, offering seamless navigation through massive datasets.
  • Wijmo FlexGrid (part of Wijmo by MESCIUS) allows you to lock headers in place for easy column reference, even with horizontal scrolling.
  • Syncfusion Grid control for JavaScript (part of Syncfusion Essential Studio) includes pinned headers that offer consistent context amidst complex data exploration.
  • Handsontable provides you with the ability to freeze rows or columns to keep key data points always in view.
