     DATA DX/0.1,1.0/
     DATA X/0.,10./
     CALL TDLIMS('X',2,X)
This will set the plot to range from 0 to 10 along the X axis.
     CALL TDLIMS('XMIN',1,0.0)
     CALL TDLIMS('XMAX',1,10.0)
This will set the plot to range from 0 to 10 along the X axis
     CALL TDLIMS('X',2,X,DX)
Sets the plot to range from -0.1 to 11.0
