Hi, I am using the StatisticalBarChart with StatisticalBarRenderer. In the DefaultStatisticalCategoryDataset, to add data, you have to call dataset.add(double mean, double standardDeviation, Comparable rowKey, Comparable columnKey). And the rowKey is display as legend at the bottom of the chart. If I have only one "RowKey", I do not want to display the legend. How can I remove it? Thanks, em
