I want to show whithin my Java application wheather a person is free or blocked on a particular date. I made an example of my intention in Power Point:

example chart

My first intuition was to use JFreeChart. Therefore I created some tasks and put them together in one taskseries for each Person.

With this data i created a Gantt chart. But in a Gantt chart every task is placed into a new Line and the axis a far away from my intention.

is it possible to create a chart like my example chart with JFreeChart? What would be the best way to do this?

Many thanks in advance

Yes, this is possible.

See this example.

  • hm, it looks like he is using task.setPercentComplete(0..1) to draw a small bar into a big bar. But my intention is to put equal sized bars in one row next to eachother (see my example chart) or I'm not getting it? thanks in advance! – menace_one Jan 10 '14 at 15:48
  • The percent complete bar is just an added feature. You can leave it out and then you still have the bars in one row next to eachother. – Hans Beemsterboer Jan 10 '14 at 15:54
  • explaining: you create a "main" task from the very start date to the very end date and name it "Person". then you create sub tasks which are the real tasks. – menace_one Jan 10 '14 at 16:18
