%% Modify Scatter Plot Matrix After Creation
% Create a scatter plot matrix of random data.

rng default
X = randn(50,3);
[S,AX,BigAx,H,HAx] = plotmatrix(X);

% To set properties for the scatter plots, use S. To set properties for the histograms, use H. To set axes properties, use AX, BigAx, and HAx. Use dot notation to set properties.
%
% Set the color and marker type for the scatter plot in the lower left corner of the figure. Set the color for the histogram plot in the lower right corner. Use the title command to title the figure.

S(3).Color = 'g';
S(3).Marker = '*';  

H(3).EdgeColor = 'k';
H(3).FaceColor = 'g';  

title(BigAx,'A Comparison of Data Sets')
