Vaadin charts: one color per category in column chart

Flow
1

Hello,
Here’s my problem:
I’d like to get a column chart with one different color per category bar.
This chart is binded to a list container, so I want also to keep the binding working.

Here’s the code:

[code]
Configuration conf = chart.getConfiguration();
conf.setChart(new ChartModel(conf, ChartType.COLUMN));
conf.getxAxis().setType(AxisType.CATEGORY);

// Binding
ContainerDataSeries series = new ContainerDataSeries(getItems());
series.setXPropertyId("categoryDescription");
series.setYPropertyId("total");
conf.setSeries(series);

chart.drawChart(conf)

[/code]Thank you for your help,
David Clesse
