Labeling the group

[Gifer]

I have a horizontal bar chart that is grouped by x-category. I would like to show the labels for the group and not for each bar repeating the label twice. See the attach for reference.

Thank you

Hello Gifer,

 I would suggest you to try using HorizontalStackedBarSeriesDefinition.
Creating two series mapping and StackGroupName to set a label. 
Here is a code snippet:

SeriesMapping seriesMapping = new SeriesMapping();

seriesMapping.ItemMappings.Add(new ItemMapping("AmountExport", DataPointMember.YValue));
seriesMapping.ItemMappings.Add(new ItemMapping("CategoryOfFruit", DataPointMember.XCategory));

seriesMapping.SeriesDefinition = new HorizontalStackedBarSeriesDefinition()
    {
        StackGroupName = "Export"
    };
RC1.SeriesMappings.Add(seriesMapping);

seriesMapping = new SeriesMapping();
seriesMapping.ItemMappings.Add(new ItemMapping("AmountImport", DataPointMember.YValue));
seriesMapping.ItemMappings.Add(new ItemMapping("CategoryOfFruit", DataPointMember.XCategory));

seriesMapping.SeriesDefinition = new HorizontalStackedBarSeriesDefinition()
{
    StackGroupName = "Import"
};
RC1.SeriesMappings.Add(seriesMapping);

This creates a similar effect to the one you are looking. Unfortunately the label is on the left side of the grouping. I have attached an image of the result.

Thank you. However I really need to show the group labels on the left side of the chart

Hello Gifer,

At present, we do not support this case. 

I would suggest that you enable labels only on one of the series and hide for the other. This will not work very well if the data point for the series with a label has much smaller value compared to the one without label.
