What's the proper way to display text with condensed line heights in a NSTextField?

I'm trying to understand how to properly display text with condensed line spacing in a text field. When I set paragraph style properties lineHeightMultiple, maximumLineHeight, and minimumLineHeight I can achieve the effect of condensing the lines, but one side effect is that the top line of text just gets clipped off. So I thought that I'd just be able to move the text down with NSBaselineOffsetAttributeName (using a negative value), but that doesn't seem to have any effect. I'm using a line height here of 70% of the point size, but the clipping gets far worse the more condensed it gets.

1) Is there a better way to produce a condensed font line spacing?

2) Or how would you move the text rendering downward so it doesn't get clipped.

Thanks!

    paragraphStyle.allowsDefaultTighteningForTruncation = paragraphStyle.lineBreakMode != NSLineBreakByWordWrapping && paragraphStyle.lineBreakMode != NSLineBreakByCharWrapping && paragraphStyle.lineBreakMode != NSLineBreakByClipping;

    NSAttributedString *attributedString = [[NSAttributedString alloc] initWithString:@"Hello\nThere" attributes:attributes];
    self.label.attributedStringValue = attributedString;
