Figure 23-23Effects of Scaling on Label Direction

Labels begin at the current pen location and thus are drawn parallel to the directional line, not necessarily on it. Also, negative parameters have the same effect on direction as described for the DI command.

At least one parameter must not be zero. The ratio of the parameters to each other is more important than the actual numbers. The table below lists three common label angles produced by using ones and zeros.

Table 23-19

DR Command	Label Direction
DR 1,0	horizontal
DR 0,1	vertical
DR 1,1 or DI 0.7,0.7	diagonal from P1 to P2
(any parameters equal to each other)

The relative size and sign of the two parameters determine the amount of rotation. If you imagine the current pen location to be the origin of a coordinate system for the label, you can see that the signs of the parameters determine in which quadrant the label is in.
