As shown in the figure above, how to calculate the cyclomatic complexity of chart and chart2, and why chart4 equals 4 but chart2 equals 6?(both of them contain a trigger, so the cyclomatic complexity is 1 more. If no trigger, the cyclomatic complexity of chart is 3, chart2 is 5.)

Hi Chenchen,
The cyclomatic complexity in Stateflow is determined by summing the number of graphical Stateflow decisions and the number of MATLAB code decisions within the Stateflow component, and then adding one for the default path. Graphical decisions are those based on the connections drawn within a Stateflow chart, while MATLAB code decisions are based on code written in the MATLAB action language.
For more information on calculation of cyclomatic complexity in Stateflow, you can refer the following documentation:
These resources include a decision count table that shows how the metric calculates decision counts for the common Stateflow components.
