look at the Axis handle, the labels of a polar plot are additional
children  of "Text" . Try this example :


clf
t = 0:0.01:2*%pi;
polarplot(t, -1 + sin(t));
A=gca()  // get the axis handle
A.children//  look at all its children
//The labels are those of "Text" type
id=find(A.children.type="Text" )// get their id
//then modify the properties of the handles
A.children(id).visible="off" // no labels
A.children(id).visible="on" // all labels
A.children(id).text="mylabel" // change labels
for k=id
    A.children(k).text=string(k);
end
