[Matplotlib-users] markeredgecolor

[Sascha S. <sc...@te...>]

Hi,

I already posted this some days ago to the list but I'm still hoping for =
answers...

I don't like the blackedge of the marker symbols very much. Therefore I c=
hanged the markeredgewidth to zero. But this isn't the appropriate soluti=
on because it makes the markers + and x vanish. Is there a possibilty for=
 the markeredge to inherit its color from the marker symbol?

Thanks a lot,
Sascha

I'm not sure of your scenario, but you can specify that the marker edge and face 
colour are the same when calling the axes.plot() function, e.g.

   defaultMarkerColor = 'b'
   ax.plot(sx, sy, linestyle='None', markersize=defaultMarkerSize, marker='v', 
zorder='1', markerfacecolor=defaultMarkerColor, markeredgecolor=defaultMarkerColor)

Note also that a line has a function set_markeredgecolor() where you can set the 
  edge colour.

That helped!
Thank you!

I often don't know which attributes can be used as kwargs...

Any Artist method that starts with 'set_' can be set with a kwarg.
Eg, if set_markeredgecolor is a method, you can do
markeredgecolor=something as a kwarg.

Read through the classdocs at
http://matplotlib.sourceforge.net/classdocs.html for the object of
interest, eg for lines (Line2D), see
http://matplotlib.sourceforge.net/matplotlib.lines.html

Also, you can call set(object) on any object and it will return the
current properties and their values (see also example/set_and_get.py)

BTW, the set and get introspection functionality was recently moved out of 
the pylab interface and now resides in matplotlib.artist so API
developers can use it as well
