It might be better to display icons rather than a progress percentage bar just because if the estimate changes up or down over the course of the project you will find your percentages bouncing around accordingly.
If you were to stick to the progress bar theme though I would suggest just using the difference between the updated and start dates combined with the estimate to calculate how many percent you are through the project, though obviously thats a fairly standard and dull way of doing things.
If you wanted to jazz up the progress bar though you could adorn it according to the project status so for projects that have overrun, days(updated_date - created_date) > days_estimate, you could have flames coming out of the end of the bar and perhaps an image of a devil waving a pitchfork then icicles for frozen projects etcetc...

也许基于证据的调度？ ;) http://www.joelonsoftware.com/items/2007/10/ 26.html

显示图标而不是进度百分比条可能更好，因为如果估算在项目过程中向上或向下变化，您会发现百分比相应地上下波动。
如果您坚持使用进度条主题，但我建议您仅使用更新日期和开始日期之间的差异结合估计来计算您完成项目的百分比，尽管显然这是一种相当标准且乏味的做法事物。
如果您想让进度条变得活泼，您可以根据项目状态来装饰它，因此对于已经超支的项目，days(updated_date -created_date) > days_estimate，你可能会看到火焰从酒吧的尽头冒出来，也许还有一个魔鬼挥舞着干草叉的图像，然后是冰冻项目的冰柱等等……
