After you run a simulation with BERTool, the resulting data set in the data viewer has an active menu in the Confidence Level column. The default value is off, so that the simulation data in the BER Figure window does not show confidence intervals.
To show confidence intervals in the BER Figure window, set Confidence Level to a numerical value: 90%, 95%, or 99%.

The plot in the BER Figure window responds immediately to your choice. A sample plot is below.

For an example that plots confidence intervals for a Simulink simulation, see Example: Using a Simulink Model with BERTool.
To find confidence intervals for levels not listed in the Confidence Level menu, use the berconfint function.
