function plotMetric(Metric,xyRec,iOptRec,p,i,method)
%PLOTMETRIC Plots the criterion with the newly added receiver and the
%already chosen receivers.
%   Plot the metric/criterion of a SED algortihm for every iteration.
%   Inputs:
%    * Metric - criterion values for every receiver
%    * xyRec - xy coordinates of receivers
%    * iOptRec - chosen optimal receivers
%    * p - configuration of subplots
%    * i - iteration number
%    * method - method string for displaying in the title

% Plot the receivers on a map
