How to Create Freehand Input Signals in the Signal Editor in Simulink

Freehand signal data is data you add graphically. With the Signal Editor, you can create and edit freehand signal data using a mouse or touchscreen. You can draw your own signal lines or points, use MATLAB® expressions to enter data, move signal lines or points across the canvas, take an image of the lines of the canvas, and add the data to the Signal Editor.
