Angle is a numeric-expression that specifies the amount of rotation for all subsequently drawn lines. The rotation is done about the logical pen position when PIVOT is executed. Positive values rotate counter-clockwise. Non-zero values of PIVOT cause the physical and logical pen positions to be different. Logical pen movement is unaffected. LABELs and AXES statements are unaffected.
The current trigonometric mode (RAD or DEG) determines the units for angle. The default mode is RAD.
