% plotProfile: plot plate reader analysis data on a given x-axis.
%
%   plate = cell array returned by importPlate2 or subsequent processing
%   xvalues = values to use on x-axis for each data point
%   fieldname = the name of the field (string) in <plate> to plot, e.g.
% 'CFP_ratio_mean', if the field is an array (e.g. 'CFP_ratio') then the
% mean value over the timecourse will be plotted.
%   idxs = list of indexes of the wells (1...96) to plot ([] means plot all)
% linespec = plot options (see also PLOT).
