Plot Circle with XY Graph

Open Model

This example plots a circle in Simulink using an XY Graph block.

The ex_xygraph_block_circle model computes a circle of radius 4, centered at the origin of x-y plane.

The plotted functions are:

$x = 4 \cos (\theta)$

$y = 4 \sin (\theta)$

When you simulate the model, a figure window appears showing the plotted circle.
