成图如下:
a图为例子,纵坐标是1-12月,横坐标是不同的因子。如左下第一格表示的就是x1与AO因子在十二月的相关性。
(a/b/c是x1因子,d/e/f是x2因子)
首先要计算出每个相关系数(可以在SPSS中完成),然后将它们按矩阵型输入到excel中,如下:
接着在matlab中读入数据,直接画图:
Matlab
corr = readtable('AONAODA.xls','Sheet','Sheet2');
A1 = table2array(corr(1:12,2:4));
A2 = table2array(corr(1:12,7:9));
A3 = table2array(corr(1:12,12:14));
A4 = table2array(corr(15:26,2:4));
A5 = table2array(corr(15:26,7:9));
A6 = table2array(corr(15:26,12:14));

sub1 = subplot(2,3,1);
imagesc(A2);

yticklabels({'Jan','Mar','May','Jul','Sep','Nov'});
pos=set(sub1,'Position', [0.06 0.58 0.22 0.38]); %设置位置
txt = {'(a) 1984-2000'};

set(h,'YTick',-1:1:1,'fontsize',9);%设置colorbar单位
pos3=set(h,'Position', [0.92 0.1 0.022 0.85]); %设置colorbar位置
上面的代码大部分都是重复的,只要弄懂第一个子图怎么画,后面的改变量就行。
(CMap是我下的颜色库,也可以用matlab自带的)
另外,多子图的colorbar的设置需要在最后单独写几行代码,可根据自己需求更改。
祝大家画出好看的图。
