Rotation of labels when the angle is between 90° and 270°

[PhilippeMeyer68]

Currently the labels are following the circle and become difficult to read on the left side of the dendrogram.
Is it possible to add an argument to revert them when the angle is between 90° and 270° such as in the left part of the following picture

Thank you very much,

Actually this is not difficult to do, you just have to change the lines of code 185-200 by:

    if addlabels == True:
        assert len(Z2["ivl"]) == len(label_coords), (
            f'Internal error, label numbers for Z2 ({len(Z2["ivl"])})'
            f" and for calculated labels ({len(label_coords)}) must be equal!"
        )
        for (_x, _y, _rot), label in zip(label_coords, Z2["ivl"]):
            if _rot > 90 and _rot < 270 :
                _rot = _rot + 180
                ha = "right"
            else:
                ha = "left"
            ax.text(
                _x,
                _y,
                label,
                {"va": "center"},
                rotation_mode="anchor",
                rotation=_rot,
                fontsize=fontsize,
                ha=ha,
            )
