gantt chart like stacked horizontal

[Francesco Mascarello]

Hi!

I’m reading the complete documentation of JFreeChart, it is new for me.

I like to create a Gantt chart with the bar in the horizontal position ( like the horizontal stacked bar chart), or a horizontal stacked bar chart with the timeline in the horizontal axis.

Any idea?

Thanks,
Francesco Mascarello.

Hi Francesco,

There is a program called GanttDemo.java in the com.jrefinery.chart.demo package. Give that a try...

Hi Dave,
I've tried a lot with GanttDemo without result.
I don' t know how to change the code for display the series in the same line, now the series are displayed under the previous one.
With a lot of series is necessary to reduce the number of categories.


Any other idea?
Thanks,
Francesco Mascarello.



P.s.:

I' ve try the StackedHorizontalBarChart, but is not the good solution because I need to create also some empty bar; the code is:


public static JFreeChart createStackedHorizontalBarChart ....
....

DateAxis rangeAxis = new HorizontalDateAxis(rangeAxisLabel);
//ValueAxis rangeAxis = new HorizontalNumberAxis(rangeAxisLabel);

(In the data is necessary to put the long value of the Date() )
