Scatter Plot in C#
Create scatter plots in C# with AddScatter — marker shapes, borders, and regression overlays. Self-contained SVG from .NET, no JavaScript required.
Scatter Chart
ChartType.Scatter — dots only, no connecting line.
When to use a scatter plot
Reach for it when
- Looking for correlation, clusters, or outliers between two measures.
- Distributions with many points, where individual markers show density that a line would hide.
- Paired with AddLinearRegression when you want to state the trend as well as show it.
Use something else when
- Few points. With six markers there is no distribution to see; a table or column chart says more.
- Heavy overplotting without reduced opacity or smaller markers — a solid blob encodes nothing.
- A third dimension crammed in by colour alone; use a bubble chart and encode it as size.
Scatter Plot in C#
Lifted verbatim from the chart types reference, so it compiles against the shipped API. See the API reference for every overload and the exact data types each series method accepts.
