Enum NaKey 

pub enum NaKey {
    Auto,
    Always,
    Never,
}

ScaleFillBinned::na_key (sipemu/ggplot-rs#269): whether the legend’s “no data” key is shown.

Variants

Auto

Today’s behaviour (unchanged default): the key appears only when at least one trained value was Value::Na.

Always

Always show the key, with its count ("no data (0)" when nothing is missing) — a plot rendered once per animation frame needs a legend that doesn’t grow or shrink as the missing count changes from frame to frame.

Never

Never show the key, even with Value::Na trained — the caller draws its own “no data” explanation elsewhere.
