The WPF step line chart is similar to the line chart, but it does not use the shortest distance to connect two data points using diagonal lines. Instead, the step line chart uses vertical and horizontal lines to connect data points in a series forming a step-like progression.
Rotate the step line chart to plot data vertically and view data from a different perspective.
Use multiple axes to plot different data sets that widely vary from one other.
The WPF step line chart handles empty or null data points elegantly.
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.
Data labels display information about the data points. Customize their foreground, border, and background. Use template support to customize the default appearance with a desired view. You can rotate a data label by a given angle.
