marginal plot (边际图)

Creates (scatter, contour, regression, etc.) main plot with upper and right marginal distributions (histogram, boxplot, violin, rug, etc.).

marginalPlot: Visualization of grouped data with main plot and marginal plots

Creates (scatter, contour, regression, etc.) main plot with upper (X-axis)

and right (Y-axis) marginal distributions (histogram, boxplot, violin, rug, etc.).

A total of 99 combinations are currently available.

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();

Demo 2 : Change colors and labels

% 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.ClassName = {'AAAAA','BBBBB','CCCCC'};
MP.CData = [122,117,119; 255,163, 25; 135,146, 73; 126, 15,  4;  30, 93,134]./255;
MP.draw();

MP.axM.XLabel.String = 'Thank U very much for your five-star review !!!';
MP.axM.YLabel.String = 'Rate me please.';
MP.axU.YLabel.String = 'Marginal plot';
MP.axR.XLabel.String = 'Made by slandarer';
