  1. Thanks. I have made the modification to my gantt charts… Great improvement.

  2. As always, sage advice from the master! 🙂

  3. Very cool

  4. Tony,
    Good article! Do you know of a way to do vertical bars on Gant?

  5. Rob… you can display and re-format vertical lines in the same ‘Gridlines’ dialog box. Try the various ‘column’ items in the left ‘Line to change’ list.

  6. Isn’t that the pot calling the kettle black, Dale?
