In the future, I think it would be great if the Gantt chart supported date/time or would handle the calculations in 2 different ways (or modes if you like). He described the use of his chart in a 1919 book, Organizing for Work.13 Figure 12.2 shows a Gantt chart for the fictional park maintenance. The end date is assumed to be (12 am) but that's not displayed so the user may assume actual day which ends on (23:59:59 PM).Īt the minimum the Gantt chart should allow me to override the duration.

#Ganttproject use hours software#
GanttProject is my favorite software because it generates a PERT chart. You might say, why I don't add +1 day to end date,- yes that will fix the duration calculation but now the displayed end date in tooltip will be interpreted wrong by the user (the bar lengths do render correctly). Use these project management software with Gantt chart to easily create, schedule. This is weird because the documentation says otherwise (from docs: If start/end/duration all present - Check that duration is consistent with start/end times. The basic rules is: If a task requires 3 man-days and a person who is doing this task is 50 available then the task must become 6 days long. In effort-driven scheduling a length of a task depends on the amount of required work (in man-days or man-hours) and availability of resources. I specified in my json start/end dates and duration but the gantt chart ignores my duration and simply subtracts the dates and returns 0 days for the duration. GoogleCodeExporter commented on Jun 28, 2015. Obviously, this causes the task's visual bar not to render.Īs a workaround, I decided to calculate the duration myself, ie. If you want to push for some features, I might help to donate and ask the dev team to develop 'your' feature with priority (if possible). This is a free product, build by people in their free time.

A day still has 24 hours and this task has a duration of 1 days. To all who complain why things do not advance. The problem is that when a task begins, for ex: on Sep 21 and ends on Sep 21, the gantt chart calculates this to have a duration of 0 days which in the context of scheduling is incorrect. It doesnt try to be an instant messaging platform or a content management system or an intranet portal it simply provides an intuitive, attractive interface for tracking tasks, dependencies. The tool does one thing well: project management.

We're using Google Gantt chart in our project management software to display scheduled tasks. GanttPRO provided the full spectrum of features without feeling overwhelming or being too expensive.
