Function generate_ratio_custom_comparison_plot 

pub fn generate_ratio_custom_comparison_plot(
    results: &[AnalysisResults],
    comparison_index: usize,
    group_indices: Range<usize>,
    output_path: &Path,
    include_estimate_column: bool,
) -> Result<(), Box<dyn Error>>

Generates a line plot for the various columns from a custom comparison.

Arguments

• results - A slice of AnalysisResults, one for each analyzed file.
• comparison_index - The index of the custom comparison to plot in the custom_comparisons array.
• group_indices - The range of indices for the groups to compare.
• output_path - The path where the plot file will be written.
• include_estimate_column - Whether to include the estimate ratio column.

Returns

• Result<(), Box<dyn std::error::Error>> - Ok if successful, otherwise a boxed std::error::Error.
