Before Change

        if self.attr_size is None:
            size_data = np.full((self.n_points,), self.point_width,
                                dtype=float)
        elif self.attr_size == "Stress":
            size_data = scale(stress(self.master.embedding, self.master.effective_matrix))
            size_data = self.MinShapeSize + size_data * self.point_width
        else:
            size_data = \
                self.MinShapeSize + \
                self.scaled_data.get_column_view(self.attr_size)[0][self.valid_data] * \
                self.point_width
        nans = np.isnan(size_data)
        if np.any(nans):
            size_data[nans] = self.MinShapeSize - 2
            self.master.Information.missing_size(self.attr_size)

After Change

        Handle "Stress" size option.
        Everything else is passed to Scatterplot"s compute_sizes

        if self.attr_size != "Stress":
            return super().compute_sizes()

        def scale(a):
            dmin, dmax = np.nanmin(a), np.nanmax(a)
            if dmax - dmin > 0:
                return (a - dmin) / (dmax - dmin)
