Hey all,
I would like to create a two-dimensional boxplot. So far I only managed to create 1D Boxplots with fixed x-value using boxchart. The result should be something like the below image:
On stackoverflow I found a solution for R and Python (matlplotlib), unfortunately I didn't find anything for Matlab.
R-solution
Python (matplotlib) solution
I would be happy if someone has a clever idea for the solution. Thanks in advance and best regards,
Tom

x = rand(1,30);
y = rand(1,30);
tiledlayout(1,2)
nexttile
scatter(x,y,'filled','r');
nexttile
boxchart(median(y)*ones(size(x)),x)
hold on
boxchart(median(x)*ones(size(y)),y,"Orientation","horizontal")

Have a look at this code:
It describes how to do 3D boxplots, if you only have one grouping, it would go down to 2D

Dear Constantino,
Thank you for your quick reply, unfortunately this does not work for the desired plot as I would like to display the information in x-direction as well.
