hi am doing a polar plot of the radiation pattern of an antenna. the polar plots represents the value of the power in dB's and the dB go from -40dB to 0dB as the angle theta changes from 0 to 2*pi rads the polar plot in python goes with positive values how can i solve this problem rough example example: power = arange(-40,0,-10) theta = arange(0, 2pi,pi/12) polar(power,theta) title.....? how can i show the step on the polar plot plot(-40, -30,-20,-10,0)
