Store data logged by Scope signal viewer        For new models,
use the Dataset logging format. If you use the Dataset format
for signal logging, then Simulink® does not log the signals
configured to be logged in the Signal Viewer. Explicitly mark
the signal for signal logging by using the Signal Properties
dialog box. To access the Signal Properties dialog box, right-
click a signal and from the context menu, select Properties.
Simulink software creates instances of this class to log data
displayed on Scope viewers (see Visualize Results). In
particular, if you have enabled data logging for a model,
Simulink software creates an instance of this class for each
scope viewer enabled for logging in the model and assigns it to
a property of the model's Simulink.ModelDataLogs object. The
instance created for each viewer has a Name property whose value
is the name specified on the History pane of the viewer's
parameter dialog box (see Scope for more information). The
instance also has an axes property for each of t
