Overview
WPF Smith Chart is a data visualization control for high-frequency circuit applications to visualize the complex functions. It has two sets of circles to plot the parameters of transmission lines.
Rendering mode
Visualize both the impendence and admittance of transmission lines using the WPF Smith Chart control.

Impedance transmission
An impedance Smith chart is composed of two families of circles such as normalized resistance circles and normalized reactance curves.

Admittance transmission
An admittance Smith chart is composed of two families of circles such as normalized conductance circles and normalized susceptance curves.
Axis
A Smith chart has horizontal and radial axes. The appearance of both axes can be customized, such as their labels and major and minor grid lines.

Horizontal axis
The horizontal axis is used for plotting resistance values of transmission lines.

Radial axis
The radial axis is used for plotting reactance values of transmission lines.

Axis customization
Customize the appearance of an axis line using dash style and axis line color properties.
Series
Plot any number of line series to represent data. Also, use different color models and customizable options.

Line series
Customize a line’s stroke and width by using the interior and stroke width properties of line series.

Marker
Add marker shapes to a series to indicate each data point.
Data labels
Easily annotate data points with labels to improve the readability of data.

Data label
Data labels provide additional information about the data points. By default, the data labels are displayed at the top of the data point.

Smart data label
The data labels are smartly arranged to avoid intersection when there are large amounts of data.
Legends
Legends provide additional information that is helpful in identifying individual series in a Smith chart. They can be docked to the left, right, top, or bottom positions around the plot area. By clicking a legend item, we can toggle series visibly.

Tooltip
A tooltip displays a pop-up with additional information when the mouse is hovered over a data point.
