pub fn chart_notes(
rows: &RowsRead,
clipped: Option<&Clipped>,
middot: &str,
) -> Vec<String>Expand description
What a chart says under the plot about its input, one line each: that it is a
sample, with the seed that draws it again, and how many values a range left out.
Empty when it shows every row and every value. middot joins the seed on.
