[Problem with order of series]

Hi, 

I am new using jChartFX and I have a problem showing a set of series.

I have 4 series (Yield, Density, Cost, kWH Per Ton) and I create them in that order, when I apply the Gantt gallery to the whole chart, the series appear inverted (kWH Per Ton, Cost, Density, Yield).

If I apply the Gantt gallery to each series, they are shown in the correct order.

I don't know if this is a problem with my configuration or something else.

In the next link you can see an example:

To try one or another approach you just need to comment chart1.setGallery(cfx.Gallery.Gantt); or series1.setGallery(cfx.Gallery.Gantt); (for each series)

 Does anyone know how can I correct this?

Thanks,

 Alberto
