function dcprDataPlot3(DS, plotTitle, displayAnnotation)
% dcprDataPlot: Plot of 3D data for data clustering or pattern recognition
%	Usage: dcprDataPlot3(DS, plotTitle, inputName, pointLabel)
%		DS: data to be displayed
%			DS.input: input part
%			DS.output: output part (this part could be missing for DC)
%			DS.dataName: data name (or description)
%			DS.inputName: data input name
%			DS.annotation: data annotation for each data point
