pub fn hidden_legend_constraints( self, constraints: (Constraint, Constraint) ) -> Chart<'a>

Set the constraints used to determine whether the legend should be shown or not.

Examples
let constraints = (
    Constraint::Ratio(1, 3),
    Constraint::Ratio(1, 4)
);
// Hide the legend when either its width is greater than 33% of the total widget width
// or if its height is greater than 25% of the total widget height.
let _chart: Chart = Chart::new(vec![])
    .hidden_legend_constraints(constraints);
