%% Plot Grouped Data % Copyright 2015 The MathWorks, Inc. %% % Load the sample data. Create data vector |x| from the first column of % the data matrix, which contains sepal length measurements from three species % of iris flowers. Create data vector |y| from the second column of the % data matrix, which contains sepal width measurements from the same flowers. load fisheriris.mat; x = meas(:,1); y = meas(:,2); %% % Create a scatter plot and six kernel density plots to visualize the relationship % between sepal length and sepal width, grouped by species. scatterhist(x,y,'Group',species) %% % The plot shows that the relationship between sepal length and width varies % depending on the flower species.
