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

https://stackoverflow.com/questions/53849636/draw-a-double-box-plot-chart-2-axes-box-plot-box-plot-correlation-diagram-in

I would be happy if someone has a clever idea for the solution. Thanks in advance and best regards,

Tom

在 MATLAB Online 中打开

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:

https://uk.mathworks.com/matlabcentral/fileexchange/68006-boxplot3d-create-three-dimensional-boxplots4

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.
