As a workaround for a current versions, one may add an invisible item. For example, handles, labels = ax.get_legend_handles_labels()
if len(handles) == 1:
from matplotlib.patches import Circle
handles.append(Circle((0,0), 1, visible=False))
labels.append("")
plt.legend(handles, labels,
bbox_to_anchor=(0., 1.02, 1., 0.102), loc=3, mode='expand',
numpoints=1, ncol=2, borderaxespad=0.) |

Thanks @leejjoon this looks 👍 Is it easy to add/update a test for this? |

Bump. I'm happy to merge this, but it'd be even better if we had a test to ensure we don't digress in the future. Thanks @leejjoon |

Basically, the legend "expand" mode fails when there is one item to show.
The PR fixes this problem.
