horizontal text alignment relative to the x-coordinate. Possible values: 0 or "left" - left-aligned (text starts at x), 0.5 or "middle" (default) - text is centered on x, 1 or "right" - right-aligned (text ends at x). There are two special alignments: "inward" (aligns text towards the plot center) and "outward" (away from the plot center).
