Anchor points and rotated text in PROC SGPLOT

The TEXT statement in PROC SGPLOT supports the ROTATE= option to rotate the specified text. It is worth knowing how the ROTATE= option interacts with the POSITION= option, which determines the anchor point at which the text is positioned. Briefly, the text is positioned FIRST, then the rotation occurs. The
