Is it possible to plot an additionally rectangle into a Bode plot ?

I am working with digital filters and want to highlight the area in which the signal is attenuated. I am using the bodeplot() function and tried to plot a the area with the patch() function, because i want the rectangle to be transparent, but it seems like it won't work that way. If you know how I could solve that problem I would really appreciate it!

Best regards

The plot produced by the bode function will not allow any alterations.

The solution is to use the bode function with three outputs (magnitude, phase, and frequency), then plot the amplitude and phase in your own subplot call. You can then do anything with the plot you can do with any other subplot.
