I'm looking for a "simple" solution for a Gantt chart. We have issues in a project we have and I'd like to create a custom filed that has the year in it and based on that value and a start/end date (and if I'm lucky also use an estimated start/end) it shows each issue in the chart as an item. If I could use both actual and estimated I'd have 2 lines for each item (see pic for my bad example)
Jan Feb Mar Apr May....etc

I've played around with a couple of them but they seem overly complex and I couldn't get them to break apart by year or a setting in the issue.
Any suggestions on what might fit the bill?
