~/matplotlib/lib/matplotlib>diff markers.py_broken markers.py 190c190 < path = Path(verts) --- > path = Path(self._marker) PS - I tried to log into https://github.com/matplotlib/matplotlib/issues using my mailing list password to create a bug report, but it would not accept it, so you get it this way. DOCUMENTATION NOTES 1) in the table for marker vertices it states http://matplotlib.sourceforge.net/api/artist_api.html#matplotlib.lines.Line2D.set_marker verts a list of (x, y) pairs in range (0, 1) it really should be just normalized or abs(1), (0,0) being center, and hence the (x,y) values should be in the range (-1,+1). Would be good to add an example x=np.linspace(0,1,10)**2 plot(x,c='r',marker=((-1.,-1),(1.,-1),(1.,1.),(-1,1.),(-1,-1)),ms=10) 2) the source also support to just provide a path as a marker, which (a) is cool, and (b) seemed natural as internal many things are done a paths, and even complies paths are generated from the $...$ syntax math. In any case, this should be added to the documentation for allowed markers path a matplotlib.path.Path object import matplotlib.path as path x = np.linspace(0,1,10)**2 p = path.Path(((-1.,-1),(1.,-1),(1.,1.),(-1,1.),(-1,-1))) plot(x,c='r',marker=p,ms=10) or a cool example that you may want tot add to the library... import matplotlib.path as path # define codes P = path.Path Pm = P.MOVETO Pl = P.LINETO Pc = P.CLOSEPOLY c = [Pm] + [Pl]*3 + [Pc] cx=c*2 # define basic path r=np.array(((-1.,-1),(1.,-1),(1.,1.),(-1,1.),(-1,-1))) # we add second closed path of half size but reverse parity rh=0.5*r[::-1] rx = np.vstack((r,rh)) p = path.Path(rx,codes=cx) x = np.linspace(0,1,10)**2 plot(x,c='r',marker=p,ms=10) PS - I guess I need to figure out how to do such updates w/o requesting action from the lest eventually. Just to emphasize (2a): COOL!!! Wishlist: Can we add a "transform" parameter to overwrite self._transform? I suppose this would have to go many places. "set_marker_transform" Maybe add to MarkerStyle from transforms import Transform def self.set_transform(self, transform = IdentityTransform()): assert isinstance(x, Transform) self._transfrom = transfrom() Maybe less fancy, and better for starters, to add an angle "set_marker_rotation(angle)" using Affine2D().rotate_deg(angle) -Alexander ------------------------------------------------------------------------------ Learn Windows Azure Live!
