How to display Chart diagram in a report, using report generator?

Hi,

I have a problem with the visualization of Chart diagram and related properties in my model.

I using this code line (in a matlab script) to search all the subsystem object (including chart):

allsubsysObj = modelObj.find('-isa','Simulink.SubSystem','-or','-isa','Simulink.ModelReference','-depth',1);

The script find the number of element that i'm expected (2 chart and 2 subsytem) but when i tried to put the diagram figure i obtained the inner content of the subsytem and the chart.

auxpara = CenterDiagram(Diagram(allsubsysObj(1)),R);

Cap = Text(strcat("Figure ",num2str(ChCounter),".",num2str(FigCounter),": ",allsubsysObj(1).Name," subsystem"));

Cap.Style = [{FontSize(Str.CapFontSize)},{Color(Str.CapColor)},{Bold(true)},{HAlign(Str.CapAlign)}];

FigCounter = FigCounter + 1;

subsec.add(auxpara);

subsec.add(Cap);

subsec.add(LineBreak());

How i can insert only the top level diagram of the chart?

Hi Tommaso,

To visualize only the top-level diagram of a chart in Simulink, you may refer to the below steps:

1. Use the "get_param" function to retrieve the handle of the chart or subsystem you want to visualize.
2. Set the "ShowPortLabels" parameter to 'none' to hide the inner contents.
3. Use the "Simulink.BlockDiagram.createSubsystem" function to capture the diagram as an image.
4. Insert the captured image into your report.

The following is a sample example to demonstrate the same:

% Get the handle of the chart or subsystem
% Replace 'model_name/Chart' with the actual path to your chart or subsystem
chartHandle = get_param('model_name/Chart', 'Handle');

% Set to show no port labels, which hides inner contents for visualization
set_param(chartHandle, 'ShowPortLabels', 'none');

% Capture the diagram as an image
Simulink.BlockDiagram.createSubsystem(chartHandle);

% Now you can use the captured image in your report

You may refer to the following MathWorks documentation links to have a better understanding of the same:

Hi,

using your example (for my scenario):

---------------------------------------------------------

% Finding all SubSystems at level 1

allsubsysObj = modelObj.find('-isa','Simulink.SubSystem','-or','-isa','Simulink.ModelReference','-depth',1);

SubsysNum = numel(allsubsysObj);

% for SecCounter = 1 : BlockNum.

for SecCounter = 1 : SubsysNum

% Getting the specific handle

subsysObj = allsubsysObj(SecCounter);

subsysObj_Chart = subsysObj;

% Get the handle of the chart or subsystem

% Replace 'model_name/Chart' with the actual path to your chart or subsystem

chartHandle = get_param(subsysObj_Chart.Name, 'Handle');

% Set to show no port labels, which hides inner contents for visualization

set_param(chartHandle, 'ShowPortLabels', 'none');

% Capture the diagram as an image

Simulink.BlockDiagram.createSubsystem(chartHandle);

% Now you can use the captured image in your report

--------------------------------------------------------------------------------

I found this error:

Hi,

Ensure that the model is loaded before trying to access its components. Use the "load_system" function if necessary. Additionally, when using "get_param" to retrieve the handle, ensure that the full path to the chart or subsystem is correct. It should be the path within the Simulink model, not just the name.

OK,it works.

But unfortunately this operation change my original model putting a subsystem.

I wish to display only the top level figure of the chart.
