How to creat grouped violin plot?

Hi, how can I create a grouped violin plot like this? I have tried different violin plot function such as GitHub - bastibe/Violinplot-Matlab: Violin Plots for Matlab. But I cannot find a way to create violin plot that is grouped by their categoery. The example figure is created in Seaborn-python. But I am not very familiar with python so I can only create the figure with default setting. It will be great if somebody can help me to create it in Matlab! :)

I found this on MATLAB File Exchange: https://www.mathworks.com/matlabcentral/fileexchange/45134-violin-plot. It does pretty much what your image depicts. Hope it helps.

I know this answer might be slightly late but I recently found a good alternative on MATLAB File Exchange: https://www.mathworks.com/matlabcentral/fileexchange/136524-daviolinplot-beautiful-violin-and-raincloud-plots . This can create grouped violin plot in a nice way.

MATLAB R2024b introduces a new violinplot with a grouping option.

data = random(makedist('Weibull'),1000,8); 
xgroup = categorical(["Post 1m", "Post 6m"]);
colorGroup = categorical(["med off rest","med off walk", ...
    "med on rest", "med on walk"]);

xgroupData = repelem(xgroup,height(data),4); 
cgroupData = repmat(colorGroup,height(data),2); 
violinplot(xgroupData(:), data(:), GroupByColor=cgroupData(:))
legend(colorGroup)
