Scaling JFreeChart Boxplots with Multiple Categories
In JFreeChart, when displaying boxplots for a dataset with numerous categories and series, it can be challenging to achieve proper scaling without causing distortion in other chart elements.
Problem:
By default, setting the preferred size of the ChartPanel scales both the boxplots and the associated legend, labels, and annotations. This can result in either small boxplots or stretched non-boxplot elements.
Solution:
To prevent unwanted scaling of non-boxplot elements, focus on scaling only the Plot itself, without affecting the entire Chart.
Steps:
Set Preferred Size of ChartPanel, Not Chart:
Set the preferred size of the ChartPanel container, rather than the chart itself. Doing this ensures that only the Plot gets scaled proportionally.
Customize Plot:
Configure the Plot's dimensions, margins, and other properties to achieve the desired size and layout of the boxplots.
Alternative Approach:
Data Pagination:
Instead of scaling the entire dataset, consider implementing a data pagination mechanism. This involves breaking down the dataset into manageable chunks and displaying only a portion of it at a time. A scrollbar can be used to navigate between portions of the dataset.
