Plot Signal Data Logged to Workspace
To visualize non-real-time simulated data or real-time application data, use the MATLAB® plotting functions.
After running your real-time application and logging data to the MATLAB workspace, you can plot the data.
This procedure uses the model
sldrtex_model. To open this model, in
the MATLAB Command Window, type:
It assumes that you saved your data to the variable
The steps in this procedure assume that you have already loaded that model and have completed the steps in Set Scope Parameters for Logging to Workspace and Set Run in Kernel Mode Properties for Logging to Workspace.
In the Simulink® Editor, on the Desktop Real-Time tab, click Run in Real Time.
When the real-time application runs, it creates the
ScopeDatavariable that you configured in Set Run in Kernel Mode Properties for Logging to Workspace.
To show the structure of the variable
ScopeData, in the MATLAB Command Window, type:
ScopeData = struct with fields: time: [2001×1 double] signals: [1×1 struct] blockName: 'sldrtex_model/Scope'
To list the contents of the structure
ans = struct with fields: values: [2001×1 double] dimensions: 1 label: '' title: '' plotStyle: 0
To plot the first
The MATLAB environment plots the first
ScopeDatais not automatically saved to your hard disk. To save the variable
The MATLAB environment saves the scope data to the file
