% Demo 1 : Basic usage

% Generate three Gaussian-distributed datasets
Data1 = mvnrnd([ 2, 3], [1, 0;0, 2], 300);
Data2 = mvnrnd([ 6, 7], [1, 0;0, 2], 300);
Data3 = mvnrnd([14, 9], [1, 0;0, 1], 300);
DataSet  = {Data1, Data2, Data3};

% Create marginal plot object and draw
MP = marginalPlot(DataSet, 'MainType',6, 'UpperType',5, 'RightType',10);
MP.draw();
