How to create a scatter plot with multiple Y values for each X?

I'm trying to create a scatter plot with 3 values of Y for each X. X is a group value for each person. e.g. X=10 means there are 10 people, and for each person I want to plot 3 values. I attached an image of an example that I'm trying to basically the same exact thing.

I made a vector for X and I have a matrix with all of the values of the 3 features that I want to plot for each person, but not sure how to group it like the picture.

If I understand you want to repeat single values of Y for each X

for instance, if you have x=[1,2,3,4,5,6,7,8,9,10] then you want 3 values for each X then your Y matrix will be 30 elements.

I reccomend repeating values of x three times, e.g:

X=[1,1,1,2,2,2,3,3,3,...]

Y=[5,7,9,3,2,1,4,5,6....] here 5,7 and 9 share the same X=1 and so on

thanks for your input. With this method i'm worried that it will just stack the plots on top of each other. if i have a point with a standard deviation plotted with an error bar (as in figure) and you use the same X i worry it will stack all 3 points and errors on top of each other and you won't be able to see anything

check aboxplot you can make this grouping but using boxplots instead of scatter, maybe helps.
