MATLAB: Do Simulink Scope blocks have the ability to display the numerical value of a signal next to plots in Simulink 7.9 (R2012a)

simulink

I have been working with a Simulink model that takes some time to simulate, so I look at the plot on a Scope block to analyze my output as the model runs.

I would like to also look at the numerical value of a signal as the simulation is running. Is there an option in the Simulink Scope block to display the numerical value of a signal next to plot as a model runs?

The ability to view the numerical value of a Simulink signal in a Scope is not available in Simulink 7.9 (R2012a).

The workarounds are as follow:

1. Use a Display block in the model to look at the numerical value of a signal outside the Scope block while the simulation is running.

2. If using Simulink 7.9 (R2012a) or later, you can also right-click on a signal and show the port value as follows:

Simulink 7.9 (R2012a): Right-click the signal and select "Show Port Value".

Simulink 8.0 (R2012b): Right-click the signal and select "Show Value label of selected port".

MATLAB: Is there a glitch in Scope window in Simulink 8.4 (R2014b) and Simulink 8.5 (R2015a)

Double-clicking a Scope block for which the window is already open while the simulation is running causes the glitch for a discrete signal. The glitch appears due to a bug with the Scope block in Simulink 8.4 (R2014b) and Simulink 8.5 (R2015a).

There are two workarounds to address this issue:

1) You can switch to the new Time Scope introduced in Simulink 8.5 (R2015a) by clicking the "Try Time Scope" toolbar button on the Scope window.

2) In Simulink 8.4 (R2014b), you can check the "Limit data points to last" option and set the value to a sufficiently large number. You can also do this on the command line using the following commands:

% Select the Scope block
>> limit = 200000; % A sufficiently large value
>> set_param(gcb,'LimitDataPoints','on');
>> set_param(gcb,'MaxDataPoints',limit);
% Update the model to see the changes

MATLAB: Am I receiving an error in the Spectrum Scope block after updating the model from an earlier version to Simulink 6.1 (R14SP1)

There is a bug in Simulink 6.1 (R14SP1) in the way SLUPDATE updates Spectrum Scope blocks. To work around this issue, right-click on the Spectrum Scope block in the updated model, choose Link Options/Restore Link and then click 'Use Library Block'. This will change the spectrum block to the updated version while retaining all of the old settings.
