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");
