WinUI Step Line Chart - Show the Trend for Segments

Overview

The WinUI Step Line Chart (a.k.a WinUI Stepped Chart or WinUI 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.
