Hello!!
I would like to ask for some help. I am working on plotting 3 variable joint probability distribution. I have been researching on how to plot for several days, but I have not found any solution yet. I will also attach example of the plot I intend to perform as well as the text file of these joint probability distributions. I really appreciate any help you can provide.

To create that type of plot, I think you'd want to use surf. However, you would need to first turn your data into matrices (for Z and C at least) for the function surf, mesh, or contour to be able to plot them. See this answer for suggestions.
Currently, there are not enough data points for this approach to create a plot that looks like what you shared.
Perhaps it's simplest to get started using scatter3?
data = readtable(file);
G = findgroups(data.A);
for idx = 1:max(G)
scatter3(data.B(G==idx),data.C(G==idx),data.A(G==idx),15,data.Probability(G==idx))
hold on
end

Perhaps I'm messing up your data somehow, but the plots just don't look anything like what you shared. Could you create a 2D plot of what a single level should look like (for A==1) and share it here?
It doesn't have to be a contour plot - surf, mesh, etc. An image along with the accompanying code for what displays a single level the way you want. Then we can help you figure out how to create a stacked plot of that.
