Hi,
this used to work a couple of months ago.
In [1]: from pylab import *
In [2]: mappable=cm.ScalarMappable(cmap=cm.jet)
In [3]: mappable.set_array(array([0,1]))
In [4]: cb=colorbar(mappable, orientation='horizontal')
---------------------------------------------------------------------------
exceptions.AttributeError Traceback (most recent
call last)
/home/huardda/Conferences/Luxembourg/src/<ipython console>
/usr/local/lib/python2.4/site-packages/matplotlib/pylab.py in
colorbar(mappable, cax, **kw)
 340 if mappable is None:
 341 mappable = gci()
--> 342 ret = gcf().colorbar(mappable, cax = cax, **kw)
 343 draw_if_interactive()
 344 return ret
/usr/local/lib/python2.4/site-packages/matplotlib/figure.py in
colorbar(self, mappable, cax, **kw)
 701 if cax is None:
 702 cax, kw = cbar.make_axes(ax, **kw)
--> 703 cb = cbar.Colorbar(cax, mappable, **kw)
 704 mappable.add_observer(cb)
 705 mappable.set_colorbar(cb, cax)
/usr/local/lib/python2.4/site-packages/matplotlib/colorbar.py in
__init__(self, ax, mappable, **kw)
 474 kw['cmap'] = mappable.cmap
 475 kw['norm'] = mappable.norm
--> 476 kw['alpha'] = mappable.get_alpha()
 477 if isinstance(mappable, ContourSet):
 478 CS = mappable
AttributeError: ScalarMappable instance has no attribute 'get_alpha'
Ciao,
David
