スプレッドシートのピボットテーブルでパターンを発見し、あらゆる角度からトレンドやパフォーマンスを明らかにするインタラクティブな分析が可能

A pivot table in a spreadsheet lets you quickly summarize and explore large datasets by dynamically grouping, filtering, and aggregating data. It automatically calculates totals, averages, counts, and other metrics, reducing the need for complex formulas. This makes it easier to uncover trends, patterns, and outliers, such as comparing sales by region and product, analyzing costs by department, or tracking performance over time. By turning raw data into clear, interactive summaries, pivot tables help users make faster, more informed decisions.

Several .NET Core spreadsheet controls support pivot tables including:

  • DevExpress WinForms Spreadsheet (part of DevExpress WinForms) lets you create pivot tables that summarize, filter, and analyze large datasets with insightful data exploration.
  • Document Solutions for Excel, .NET Edition by MESCIUS enables advanced pivot table creation for fast data summarization and multi-dimensional analysis.

OHLC (オープン・ハイ・ロー・クローズ)チャートを用いて、時間経過の価格変動を表示するハイパフォーマンスデータ可視化で金融アプリを充実化

OHLC charts, short for Open-High-Low-Close charts, are a type of financial chart used to represent price movements of assets over a specific time period.
