Is there a free graphical library that supports Gantt charts with units of hours or even minutes? I've tried a few. JFreeChart was among the most promising but scaling down seems to reduce the maximum timescale represented to just a few days.

JFreeChart should be able to go deeper that days. SimpleTimePeriod can represent time down to the millisecond. Might just need to adjust the time display of the axis from the plot.

  • Yes. There's just a limit of how many units can be displayed in one go unless mistaken. That might not actually be an issue though as I could add some timescale buttons like in stock charts to change the timescale at runtime. – James P. Jun 11 '11 at 14:39

The nebula solution may solve your problem, you have access to the code so you will be able to change something if you need.

  • Good find. It apparently supports an hours and minutes view. This is for SWT so I hope it can be integrated into our Swing application. – James P. Jun 10 '11 at 08:49
