Plotting 3D scattered data using CSV

Hello,

I want to plot the participants' information ( Number of people, Ages , BMI ) of my experiment into a professional 3D plot using MATLAB.

The data showing as below: ( the data is saved in CSV file names "Participants" ):

Please anyone can help me how to do that?

T= readmatrix('Participants.csv');

x=T(:,1);

y=T(:,2);

z=T(:,3);

scatter3(x,y,z)

I am confused what is the proper way to plot these information? any suggestion

[Tala]

just copy and paste the code. it will work just fine

[Mubarak Alanazi]

I mean do you have any other idea that to present this data in better way.

[Tala]

if your data is share-able, please do so, I will take a look

I am recording data for my experiment and I want to present the participants information in my journal in better way. your suggestions is highly apprecaited.

The data attached.

I would show the corrolations between variables.

T1= readtable('Participants_1.xlsx'); 

T1.Gender = categorical(T1.Gender);
T1.Gender = double(T1.Gender);
T2=table2array(T1);

imagesc(corrcoef(T2)); colorbar
xticks([1 2 3 4 5])
xticklabels({'Age','Gender','Height','Weight','BMI'})
yticks([1 2 3 4 5])
yticklabels({'Age','Gender','Height','Weight','BMI'})

I think we dont need to plot the height and weight since BMI there.

I am not an expert in your field. If you feel you need to drop the values, you can easily do so.

T1= readtable('Participants_1.xlsx');  T1 = removevars(T1, {'Height_cm_','Weight_kg_'});

T1.Gender = categorical(T1.Gender);
T1.Gender = double(T1.Gender);
T2=table2array(T1);
%%
imagesc(corrcoef(T2)); colorbar
xticks([1 2 3])
xticklabels({'Age','Gender','BMI'})
yticks([1 2 3])
yticklabels({'Age','Gender','BMI'})
