Additional Information

Displaying many draglines during interactive commands can impair the performance of Layout XL. To mitigate these effects, use the maxDragFig environment variable to limit the number of figures that can be in a dragset.

To set maxDragFig interactively so that it takes effect in the current session, type the following in the CIW, where win is the window to which the limit applies.

win~>maxDragFig = 1000

To set a default value for maxDragFig, which will be used in all future Layout XL sessions, put the following line in your .cdsenv file.

graphic maxDragFig int 1000 nil
