[Matplotlib-users] AttributeError: 'BarContainer' object has no attribute 'autoscale_None'

[Nils W. <ni...@go...>]

Hi all,

I tried to add a colorbar to a bar plot

coolwarm = cm =  plt.get_cmap('coolwarm')
values = range(100)
cNorm  = colors.Normalize(vmin=0, vmax=values[-1])
scalarMap = cmx.ScalarMappable(norm=cNorm, cmap=coolwarm)
colours = []
for value in values:
    colorVal = scalarMap.to_rgba(value)
    colours.append(colorVal)

fig = plt.figure()
ax  = fig.add_subplot(111,projection='3d')
hist,bin_edges = np.histogram(efratio,bins=100,range=(0.,1.),density=False)
width = 0.7*(bin_edges[1]-bin_edges[0])
center = (bin_edges[:-1]+bin_edges[1:])/2
heatmap = ax.bar(center, hist, zs=z, zdir='y', align = 'center', width =
width,color=colours)
plt.colorbar(heatmap)





    mappable.autoscale_None() # Ensure mappable.norm.vmin, vmax
AttributeError: 'BarContainer' object has no attribute 'autoscale_None'

How can I fix the problem ?
