Show items between start and end dates

Thank you for your response! I have gone ahead and create the measure, but now I'm just a bit confused on where I'm applying it and what field I'm using as my date filter. So, you said to place the measure on the visual which I'm assuming you mean in the filter pane? If that's correct, do I need to set it to equal 1 in the filter pane? As for the filter drop down, which field am I using? A date field from the date table? If you had screenshots of how you'd apply this, that would be great.  You don't have to use it on a Gantt chart obviously but seeing it would be a bit easier to see where you're coming from.  I appreciate your response though!
