使用heatmap展示，可以通过2D图形，更加形象的展示市场的整体概况，或者投资组合的表现，如果方块的面积能与权重匹配那就更理想了！

data = randn(3,4)/10;
name = {’www’
‘Aris’
‘zheng’
‘.com’
‘Email’
‘ariszheng’
‘@’
‘gmail’
‘.com’
‘Power’
‘by’
‘Ariszheng’}
figure;
%mat, xlab, ylab, textmat
heatmap(data, [], [], name, ‘Colormap’, ‘money’, ‘Colorbar’, true);
title(’Portfolio HeatMap’)
