Scaling Boxplots in JFreeChart for Large Category Datasets

Problem Overview:

When displaying boxplots for a CategoryDataset with numerous categories and series in JFreeChart, a challenge arises in effectively scaling the chart elements. Setting the preferred size of the chart panel may scale the legend, labels, and annotations inappropriately. Thus, the objective is to scale only the boxplots while preserving the size of other elements.

Solution:

The recommended solution is to configure the preferred size of the ChartPanel, rather than the chart itself. This allows the chart to be drawn within a specific area, leaving the other elements unaltered.

Additional Considerations:

• Using a scroll pane to accommodate extensive charts is not advisable. Instead, consider implementing a custom implementation of BoxAndWhiskerCategoryDataset that provides pagination functionality.
• A more practical approach involves paging a portion of the dataset and adding a scrollbar to the frame to control the first displayed index.
