Stacked bar chart

No data attached, and the picture doesn't allow us to see what values are being used for the orange bars. My guess is that the orange bars currently represent the desired end date rather than the difference between the gray bar's date and the desired end date.

My bad, here it is.

So for example one grey bar shows end date of 7/29, and the current forecast of 8/31 so I'd only want that orange bar to show a small sliver and ending on 8/31. Then from there if the actual release date is 9/13 for example, then another sliver of a bar on the same row showing the actual release date.

Assuming that picture is the complete data set being used by the chart, I do not see a difference column calculating the differences between dates. You will need to calculate a difference column for the orange bars.
