How to use boxchart 'GroupByColor'

Wrong use of matlab.graphics.chart.primitive.BoxChart

Name 'GroupByColor' is not a property that can be accessed by instances of class 'matlab.graphics.chart.primitive.BoxChart'.

When I use the sample proxy in the help documentation, I always get the error above.

It seems that I cannot use the syntax

boxchart(___,'GroupByColor',cgroupdata)

The ability to group by color was added in R2020b (see this release note). If you have the Statistics and Machine Learning toolbox, you can look into using boxplot instead.

load patients 
Smoker = categorical(Smoker,logical([1 0]),{'Smoker','Nonsmoker'}); 

boxplot(Systolic,Smoker) 
ylabel('Systolic Blood Pressure') 
legend

Thank you very much, your advice is very helpful, I'll try boxplot instead.
