Using `sorted_y` could lead to incorrect data interpretation

[tayaza]

Hi there. Just realised a situation where using sorted_y could show misleading information as shown below.

Figure 1 (sorted_x='d', sorted_y=None)

Figure 2 (sorted_x='d', sorted_y='d')

Figure 1 is correct, Figure 2 is not. While, sorted_y correctly orders the horizontal bars and names, the order of the intersection dots and vertical bars is not changed. This shows Email with the intersection sets of Address, which is misleading.

Are sorted_x and sorted_y mutually exclusive? If so, can we implement a mechanism to prevent using them together?

Thanks for creating this!
