Bode Plot (`db` argument not working)

Created by: aromerorodriguez

Dear Duncan,

I have been trying to use the BodePlot function with the option to show the magnitude of the filter in normal units, i.e.: db=False. The version of gwpy that I'm using is 2.0.2

hp = filter_design.highpass(12, resample_rate, fstop=6, gpass=2, gstop=30,type='fir')
plot = BodePlot(hp, sample_rate=4096,db=False)
plt.xlim(20,1000)
plot.show()

However, I am getting the following error.

AttributeError: 'Line2D' object has no property 'db'

Thank you and best regards, Alba Romero.
