The Mux block has a new parameter, Display option , that affects the block icon. Simulink 3.0 allows you to choose a circular or rectangular shape for a sum block, whichever is appropriate for your environment. To change a sum block's shape, open its parameters dialog and select the desired shape from the Icon Shape drop-down list. Select the Apply or Ok button to apply the change. Simulink 3.0 also allows you to manipulate the position of sum block input ports by inserting spacers between ports.
All axes share the same time base, but have independent y -scales.
To set the number of axes, select the Properties button on the Scope's toolbar. New data structure gets written to the workspace when logging data. Zoom handles multiaxes. So, if you zoom one axes, the x -limits of all other axes are modified to match. Axes can be given titles.
