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)

Ran in:
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')
