Plot one or several convergence traces.

Parameters:

results: `OptimizeResult`, iterable of `OptimizeResult`, or a 2-tuple

of a label and a OptimizeResult or an iterable of OptimizeResult. The result(s) for which to plot the convergence trace. - if an OptimizeResult, draw the corresponding single trace - if an iterable of OptimizeResult, draw all traces in the same

plot as well as the average convergence trace

• if a tuple, the label names the trace(s) and the behavior is as specified above.

true_minimumfloat, optional

The true minimum value of the function, if known.

yscaleNone or string, optional
