I want to make the Gantt chart like above, and each resource can edit his/her time spent under his/her task day by day. I knew in JIRA resource can enter estimated hr, remaining hr, time spent , but the time spent is not by single day. What I want to know is for each task or each resource, how many hrs he spent on each task with calendar view, and if every day this resource is work over time or not. It's for capacity planning purpose. So is JIRA can do this or with some add-in?
