How can I use Matlab command line to [open/close/export as *.fig] signal viewer interfaces in Simulink (2021b?)

In my Simulink model, I have many Floating Scopes within various subsystems. From the Command Line in Matlab, I would like to:

• Open '/FloatingScope'
• Scale X & Y Axis Limits
• Print to Figure
• Save Figure as *.jpeg
• Save Figure as *.fig
• Close Figure
• Close '/FloatingScope'

Is this possible? I would love achieve this in this manner, otherwise I need to recreate my Floating Scopes entirely with logsout signals, which would be extremely tedious, as there are dozens of Floating Scopes within our model.

Hi Cory,

I understand that you want to [open/close/export as *.fig] signal viewer interfaces in Simulink using Command Line in MATLAB.

To implement this, kindly refer to the following steps:

1. Open the Floating Scope:

open_system('/FloatingScope')

2. Scale the X and Y-axis limits:

% Define your desired limits

xLimit = [xMin, xMax];

yLimit = [yMin, yMax];

% Set X and Y axis limits

set_param('/FloatingScope/ScopeName', 'XMin', num2str(xLimit(1)));

set_param('/FloatingScope/ScopeName', 'XMax', num2str(xLimit(2)));

set_param('/FloatingScope/ScopeName', 'YMin', num2str(yLimit(1)));

set_param('/FloatingScope/ScopeName', 'YMax', num2str(yLimit(2));

3. Print to a figure:

print('/FloatingScope/ScopeName', '-sFigure', '-dpng', 'output.png');

4. Save as *.jpeg:

saveas(gcf, 'output.jpeg', 'jpeg');

5. Save as *.fig:

saveas(gcf, 'output.fig', 'fig');

6. Close the figure:

close gcf

7. Close the Floating Scope:

close_system('/FloatingScope')

I hope this answer helps you.
