Summarize Large Datasets with Pivot Tables

December 4, 2025
Discover patterns with pivot tables in spreadsheets, enabling interactive analysis that reveals trends and performance from every angle.

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.
  • EPPlus by EPPlus Software allows you to build powerful pivot tables programmatically, enabling flexible data grouping, aggregation, and customizable reporting in Excel files.
  • IronXL for .NET by Iron Software facilitates generating pivot tables in code, helping you transform raw spreadsheet data into clear summaries, comparisons and insights.

Display Stock Data with OHLC Charts in .NET

December 2, 2025
Enrich financial apps with high performance data visualization using OHLC (Open-High-Low-Close) charts to display price movements over time.

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. Each point on the chart summarizes a single period's opening, highest, lowest, and closing prices, typically displayed using vertical bars with ticks to indicate opening and closing values. This format offers a clear and compact way to visualize volatility and market trends within a given timeframe. For developers and analysts working with financial data, OHLC charts are especially valuable for identifying price patterns, monitoring market behavior, and making informed decisions based on historical performance.

Several .NET chart components offer OHLC charts, including:

  • DevExpress ASP.NET Core Charts (part of DevExpress ASP.NET and Blazor) lets you render OHLC charts with tooltips and responsive design for real-time financial analysis.
  • ComponentOne WinForms Charts (part of ComponentOne Studio WinForms by MESCIUS) allows you to plot OHLC data for precise visualization of market trends in desktop apps.
