WPF Area Chart - Create Customizable Area Charts

Overview

The WPF Area Chart is like a line chart that represents time-dependent data and shows the trend at equal intervals, but it fills the area created by the line. This type of chart can be configured with a numerical, category, date-time, or logarithmic axis for the graph. It supports zooming, scrolling, tooltip, trackball, and selection.

WPF Area Chart with Multiple Axes

Multiple axes

Use multiple axes to plot different data sets along two or more axes having different data points and values.

WPF Area Chart with Data Marker

Area chart markers

The WPF Area Chart data points are visualized as marks with built-in symbols such as cross, square, plus, inverted triangles, hexagon, ellipses, vertical lines, horizontal lines, diamonds, triangles, and pentagons.

WPF Area Chart with Data Labels

Data labels

Data labels display information about data points. Labels’ foreground, border, and background can be customized. The template support allows customizing the default label appearance with a desired view. You can rotate a data label by a specified angle.

Code example

                    XBindingPath="Month"

            </chart:AreaSeries>
        </chart:SfChart>
    </StackPanel>
</Window>
public class Model
{
    public string Month { get; set; }

    public double Target { get; set; }

    public Model(string xValue, double yValue)
    {
        Month = xValue;
        Target = yValue;
    }
}

public class ViewModel
{
    public ObservableCollection<Model> Data { get; set; }

    public ViewModel()
    {
        Data = new ObservableCollection<Model>()
        {
            new Model("Jan", 50),
            new Model("Feb", 70),
            new Model("Mar", 65),
            new Model("Apr", 57),
            new Model("May", 48), 
        };
    }
