+An iterable object with labels can be passed to `Axes.plot()`
+-------------------------------------------------------------
+
+If multidimensional data is used for plotting, labels can be specified in
+a vectorized way with an iterable object of size corresponding to the
+data array shape (exactly 5 labels are expected when plotting 5 lines).
+It works with `Axes.plot()` as well as with it's wrapper `plt.plot()`.
+
+.. plot::
+
+    from matplotlib import pyplot as plt
+
+    x = [1, 2, 5]
+
+    y = [[2, 4, 3],
+        [4, 7, 1],
+        [3, 9, 2]]
+
+    plt.plot(x, y, label=['one', 'two', 'three'])
+    plt.legend()
