How can I create a scatterplot matrix?

Good evening,

can anyone tell me how to do a scatterplot matrix out of these 4 variables and insert also the groups in different colors??

Here is one way:

T = readtable('Stress_Reactivity.xlsx');

figure
gscatter(T.cort_3,T.diastolic_3,T.condition)

I recommend reading the documentation for gscatter for details.

I didn't know exactly what you meant by "scatterplot matrix out of these 4 variables", so I just did two variables. I assumed the binary variable condition was how you wanted to group them.
