How to implement a StackedHorizontalBarChart with dates on t

[Nik Clare]

I have a requirement for a combination gantt/stackedhorizontalbar chart, what I mean is a gantt chart where the series are stacked, not on separate lines (essentially just a StackedHorizontalBarChart with dates on the x-axis instead of numbers).

Is there an easy way to do this?

I tried a quick hack changing the StackedHorizontalBarChart so it had a HorizontalDateAxis instead of a HorizontalNumberAxis and changing the DefaultIntervalCategoryDataset to use dates instead of numbers (as the GanttSeriesCollection) but this produced bizarre results, not at all what I wanted.

All suggestions greatly appreciated.

HI

I solved this by making XYPlot with TimeSeries and BarRenderer, i somehow emulated the stacks by adding up the series values and plotting the bars over each other

hope this helps

Thanks for the feedback Sebastian.

In the end I solved this by using the GanttSeriesCollection as normal and making a couple of minor changes to the HorizontalIntervalBarRenderer so it renders all the bars at the same height.

This works perfectly.
