Scattersmith

Overview

The scattersmith insight type is used to create scatter plots on a Smith chart, commonly used in electrical engineering to represent complex impedance and reflection coefficients. It allows plotting data in terms of real and imaginary components, making it ideal for analyzing electrical circuits.

You can customize marker size, color, and lines to connect points, similar to scatter plots, but specifically tailored for Smith charts.

Common Uses

• Impedance and Reflection Coefficients: Visualizing electrical properties in transmission lines.
• Complex Data Visualization: Representing data points in terms of complex numbers.
• Electrical Engineering Analysis: Useful for RF and microwave engineering applications.
