在 Angular 試算表應用程式中過濾和分組資料

12月 19, 2023
資料過濾和分組使試算表使用者能夠輕鬆高效地管理和分析大型資料集。

Data filtering and grouping are key spreadsheet features that allow users to manage and analyze large datasets efficiently. Filtering enables users to hide data that does not meet certain criteria, making it easier to focus on relevant information. Grouping clusters related data together, which can then be summarized with functions such as sum, average, and count. These features are vital for working with extensive spreadsheets, enabling users to simplify their view, and gain insights from specific subsets of data.

Several Angular Spreadsheet components provide data filtering and grouping support including:

  • Jspreadsheet Pro supports navigating large datasets with ease using multi-level filtering and summarize key trends with dynamic group summaries.
  • Syncfusion Spreadsheet JavaScript (part of Syncfusion Essential Studio) allows you to gain insights and enhance understanding with nested grouping.
  • Infragistics Spreadsheet Angular (part of Infragistics Ignite UI) lets you simplify data exploration with drag-and-drop grouping and aggregate functions for instant summaries.
  • SpreadJS by MESCIUS supports crafting precise filters using advanced formulas and grouping data by multiple criteria for deeper analysis.

用資料分組增強 JavaScript 圖表

12月 19, 2023
Wijmo 2023 v2 將軸分組添加到 FlexChart 控制項，使圖表不那麼雜亂，更易於掃描。

Wijmo is a cross-platform UI JavaScript library that offers a comprehensive set of controls and tools for building rich, interactive web applications. Its components have zero dependencies and are written as lean TypeScript classes. Wijmo's key components include FlexGrid for data management, FlexChart for charting and data visualization, Input Controls for user input, and Report Viewer for creating and presenting reports.

The Wijmo 2023 v2 release brings data grouping support to FlexChart. Axis grouping helps to organize complex data by visually separating it into categories or subcategories along the axis, making it easier to identify trends, patterns, and outliers within each group. While data grouping has long been a staple of Wijmo's CollectionView, users requested similar functionality in FlexChart, which MESCIUS has now incorporated. You can bind FlexChart to a grouped CollectionView and set the 'axis.groupsOptions' property to enable grouped labels in your charts.

To see a full list of what's new in version 2023 v2, see our release notes.

Wijmo is licensed per developer. Developer Licenses are perpetual and include 1 year Subscription which provides upgrades, including bug fixes and new features. See our Wijmo licensing page for full details.
