Carpet plot chart

info

Charts are available with Avalonia Pro.

Carpet plots visualize how two independent variables relate to a third value by drawing a distorted grid of intersecting isolines.

When to use​

  • Engineering trade-offs: Compare two design inputs against an outcome surface.
  • Performance maps: Visualize operating regions for efficiency, pressure, or temperature.
  • Multi-variable analysis: Inspect relationships that do not fit a simple Cartesian line chart.

Code example​

XAML​

<charts:CarpetPlot Title="Performance map"
                             Height="320"
                             ItemsSource="{Binding CarpetData}"
                             AAxisPath="Speed"
                             BAxisPath="Load"
                             YAxisPath="Efficiency" />

Data model (C#)​

public record CarpetPoint(double Speed, double Load, double Efficiency);

public ObservableCollection<CarpetPoint> CarpetData { get; } = new()
{
    new(1000, 20, 62),
    new(1000, 40, 68),
    new(1500, 20, 70),
    new(1500, 40, 74)
};
