The Top C# and VB.NET Chart Controls

Since 2002, WinForms (Window Forms) has provided a powerful yet simple way to build Windows applications. When combined with chart controls via C# and VB.NET, developers have drastically transformed how they present data in these apps. From financial reporting to statistical analysis to real-time dashboard monitoring, obtaining visual insights has never been easier.

While most are designed with the end user in mind, not all chart control products are created equal. Some may cost more or provide a better range of learning resources by the developer, while others can offer broader functions like data interactivity or robust chart customization. Luckily, we're here to cut through the noise!

Below, we’ll review the top WinForms C# and VB.NET chart controls of 2024.

Essential Attributes of WinForms C# and VB.NET Chart Controls

Integrating complex charts into Windows applications isn't easy — at least not without the right WinForms chart controls. Whether you're producing stock market analytics, tracking enterprise key performance indicators (KPIs), visualizing healthcare data, or running a massive data simulation, these tools are invaluable for providing visual insights.

So, we wanted to see just how well each product could support these business use cases and overall developer objectives. Some key attributes we evaluated are as follows:

• Chart types and customization: Do the chart controls allow you to view data on a broad range of chart types and customize those charts with different color palettes, axes, display symbols, tick marks, legends, etc.?
• Interactivity and analysis capabilities: For enhanced insights, how well do the chart controls let you interact with data through scrolling, zooming, and drill-down functions, plus analyze through conditional formatting, axis grouping, error bars, etc.?
• Specialty industry use cases: Do the chart controls offer special features for specific industries? For example, financial chart types can provide analysts with indicators and overlay two different financial securities (stocks or funds) on the same chart.
• Developer experiences and resources: For each chart control, does the provider offer resources, such as samples, product documentation, tutorials, and chart templates, to enhance the developer experience? If so, how well do these help new users onboard and learn the features?
