Parameters:

XPOS = _REAL (Read and Write)

The X coordinate of the text. []

YPOS = _REAL (Read and Write)

The Y coordinate of the text. []

ANGLE = _REAL (Read and Write)

The angle relative to the horizontal at which the text string is to be plotted. []

JUSTIFICATION = _REAL (Read and Write)

The justification about the specified point (in the range 0.0 to 1.0). Here, 0.0 means left justify the text relative to the data point, 1.0 means right justify the text relative to the data point, 0.5 means centre the string on the data point, other values will give intermediate justifications.
