WPF Step Area Chart - Interactive Chart Component

Overview

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