I'm a new user of the package and wanted to check transfer function outputs 
between my circuit simulator and some other control simulation package. It 
appears that outputs from bode_plot (sympy.physics.control.control_plots) 
are in rad/s for frequency, which is the natural unit for control analysis. 
The graph produced by bode_plot  has its frequency axis shown in Hz, but 
analysis and comparison to other programs suggest that it should be 
labelled rad/s.

Is this an error, or is there some switch somewhere in the package that 
sets units for outputs to Hz and degrees, rather than radians and rad/s?

I have a work around by handling graphing, just would like to use the built 
in functions where possible. Also would like the make use of the initial 
and final exponent, in the units of the graphing output.
