Polar plot with 'xfig_polarplot_new'
% Plot coordinate transformation
variable min = 0,
max = 180,
dir = 1,
org = 45;
variable ang = [min:max:#100];
variable rad = 0.5+0.5*sin(ang*PI/180);
variable xf = xfig_polarplot_new(; min=min, max=max, origin=org, dir=dir, grid );
xf.plot( rad*cos( dir*(ang+org)*PI/180 ),
rad*sin( dir*(ang+org)*PI/180 ) ; color="red" );
xf.render("/tmp/test.pdf");
