I don't see any elegant way to do that. The easiest way I can think of is to use a derived line2d class. Something like below will work. Others may have better ideas. import matplotlib.lines class Line2DNoInterpolation(matplotlib.lines.Line2D): def recache(self): matplotlib.lines.Line2D.recache(self) self._transformed_path.get_transformed_path_and_affine = \ self._transformed_path.get_transformed_points_and_affine ax = subplot(111, projection="polar") r = np.arange(0, 1.0, 0.1) theta = 2*np.pi*r p2 = Line2DNoInterpolation(theta, r, color='r', lw=1) ax.add_line(p2) JJ On Thu, Jan 29, 2009 at 12:20 AM, jamesf0 <jamesf0@...> wrote: > > Hi, > > Im having some trouble with this "seemingly" simple task of plotting > straight lines/fitted curves on a polar plot. > > I am trying to create a plot that resembles the layout of the chart seen > below: > > http://www.nabble.com/file/p21721073/brisbane.png > > > > So far I have only been able to plot data like so: > > http://www.nabble.com/file/p21721073/AzvAlt.png > > > The blue line should be similar to the bottom line of the first example > plot.
