Display column keys of stacked bar chart vertically in jFreeCharts

问题

I am developing a javaEE application using jfreecharts. I successfully displayed my data using a stackedBarChart but the column keys (Y-axis labels) are not fully displayed because they are too large. how can I display them vertically? thanks for your suggestions

You can use setCategoryLabelPositions() like they show here.

CategoryPlot plot = (CategoryPlot) chart.getPlot();
CategoryAxis domainAxis = plot.getDomainAxis();
domainAxis.setCategoryLabelPositions(CategoryLabelPositions.UP_90));
