# Charts

The Eremex Controls Library for Avalonia UI includes powerful chart controls that help you visualize data as 2D charts. The chart controls' graphics rendering is optimized to display large data. The controls maintain high performance even when series contain millions of points.

## CartesianChart

[CartesianChart](cartesian-chart.md) allows you to plot a diagram on a Cartesian coordinate system.
