// Plot implements the Plotter interface, drawing labels.

	trX, trY := p.Transforms(&da)
	for i, label := range l.Labels {
		x := trX(l.XYs[i].X)
		y := trY(l.XYs[i].Y)
		if !da.Contains(plot.Pt(x, y)) {

		x += l.XOffset
		y += l.YOffset
		da.FillText(l.TextStyle, x, y, l.XAlign, l.YAlign, label)
