Teun has been working on a new version of his Gantt Chart webparts. Great work with some new features:
“I have been making some enhancements to the Gantt chart web part. There are basically 2 new features:
- Group by: if your underlying view uses groupings, the Gantt chart will show these groupings as black grouping containers. The start and end date of the grouping will automatically stretch to reflect start- and enddates of underlying items
- Other time partitionings: several people requested a week or year view. You can now choose between a MonthDay view (where the top bar shows the months and the second row the separate days), a MonthWeek view showing weeknumbers on the second row and a YearMonth view that shows years in the top row and months in the second. This will work better for longer time frames.”
