Hi guys,

I need to create a polar graphic with negative values with polarplot command. I already tried a lot of thing to this work, but that the program shows is the standart visualization. In this case, I need that radius values have be between -1 and 2.5. My syntax is bellow:

clear,clf
azimutal=0:%pi/90:2*%pi;
torqueA=[

a.data_bounds=[0*%pi/180,-1.0;360*%pi/180,2.5];
polarplot (azimutal,torqueA,style=-3);

I appreciate any solution. Have a nice day!
