Hi,

To plot the excel data using "From Workspace" and "Scope" blocks, please refer to the following steps:

• Assuming the Excel data is structured with one column for time and another for signal values, you can use the following script to read the data from Excel file:

% Load data from the Excel sheet
data = readtable('exampledata.xlsx');

% Extract time and signal data
time = data.Time;      
signal = data.Signal;   

% Create a data structure
simulationData = struct('time', time, 'signals', struct('values', signal, 'dimensions', 1));

% Save this structure to the workspace 
assignin('base', 'simulationData', simulationData);

• Open Simulink and drag the 'From Workspace' block.
• Double-click on the block and set the Variable name to simulationData.
• Drag a 'Scope' block and connect its input to the 'From Workspace' block to plot the data.
• Press Run in Simulink to start the simulation and click on the 'Scope' block to view the plot.

I hope this helps you to plot the data!
