[Matplotlib-users] AnchoredSizeBar Color
Hi, Is there anyway to set the color of an AnchoredSizeBar artist from the mpl_toolkits.axes_grid.anchored_artists toolkit?

[Matplotlib-users] TypeError: unsupported operand type(s) for +: 'NoneType' and 'float' on 1.2.1
After upgrading to 1.2.1 from 1.1, I'm getting an exception on the below-noted
line; any thoughts what might have changed?

Re: [Matplotlib-users] AnchoredSizeBar Color
The anchored_artists needs improvements and things are still opaque. For now you can do something like below, ``` a = AnchoredSizeBar(ax.transData, 0.1, test, loc=8, pad=0.1, borderpad=0.1, sep=2, prop=None, frameon=False) rect = a.size_bar._children[0] rect.set_ec(g) ``` `rect` is a patch instance responsible for the bar. By default its height is 0 and facecolor=none. Similarly, the text label can be accessed via `a.txt_label._text`.
