The ‘sfroot’ function is used to retrieve the Stateflow root object, which provides access to the complete hierarchy of all open Stateflow models in the MATLAB environment. Using the ‘find’ method, specific charts or elements within these models can be programmatically located and manipulated.
To access a chart object from a model, following syntax can be used:
ch = find(sfroot, '-isa', 'Stateflow.Chart', '-and', 'Path',model_path)
Here, ‘model_path’ should be replaced with the actual path to the chart within the model.
Once the chart object has been obtained, its properties—such as font style and background colour—can be modified through direct property assignments. For example, to adjust the font style used in state labels:
ch.StateFont.Name = 'Courier New';
ch.StateFont.Size = 14;
ch.StateFont.Weight = 'BOLD';
Additional properties, such as ‘ChartColor’, ‘StateColor’, and ‘TransitionLabelColor’, can also be set to customize the appearance of specific chart elements.
