WPF Step Line Chart - Show the Trend for Segments

Overview

The WPF Step Line Chart (a.k.a WPF Stepped Chart or WPF Stepped Line Chart) is similar to the line chart, but it does not use the shortest distance to connect two data points using straight lines. Instead, the step line chart uses vertical and horizontal lines to connect data points in a series forming a step-like progression.

Key features

WPF Vertical Step Line Chart

Vertical chart

Rotate the step line chart to plot data vertically and view data from a different perspective.

WPF 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 Step Line Chart showing Empty Point aka Null Point

Empty or null point chart

The WPF Step Line Chart handles empty or null data points elegantly.

WPF Step Line Chart with Data Markers

Step line chart markers

The WPF Step Line Chart data points are visualized as markers with built-in symbols such as a cross, square, plus, inverted triangle, hexagon, ellipse, vertical line, horizontal line, diamond, triangle, and pentagon.

WPF Step Line Chart with Data Labels

Data labels

Data labels display information about the data points. It provides the support for customizing the foreground, border, and background in addition to template support to customize the default appearance with the desired view. You can rotate a data label by its given angle.

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

    public ViewModel()

        Data = new ObservableCollection<Model>()
        {
            new Model("Jan", 50),
            new Model("Feb", 70),
