Another question I was recently asked was whether it is possible to remove the progress line from a Gantt chart. Sometimes when you are working on commercial projects that are fixed price, the project manager may wish to track progress in the schedule, but not necessarily share this information with the client, as it may give away their position and profit.
To remove the progress bar from your Gantt, choose Format > Bar Styles
Select the progress line and choose Cut Row.
The project will still retain the actuals, but no longer display the associated progress in the chart.
If you find that you need both a view with the progress line and a view without, repeat the above but on a separate Gantt view.
