3D dose plot and color wash

I am a beginner in matlab and now doing a project in measuring the dose at different coordinates x y z. Now I would like to plot a 3D scatter plot with different color representing the dose level and probably a color wash generated from the plot. I have input the data to an excel spreadsheet with 4 columns x y z dose. Thank you in advance for your help.

T = readtable('myfile.xlsx') ; 
scatter3(T.(1),T.(2),T.(3),[],T.(4),'filled')

Thank you. Is it possible to further make a 3D volume color wash from the scatter plot? Also, can I merge the plot/ volume color wash with 3D file in obj format?

Can be done. for this I suggest to attach your data.

I attached the data xlsx here. Thank you.

T = readtable('https://in.mathworks.com/matlabcentral/answers/uploaded_files/1099290/test%20dose.xlsx') ;

Warning: Column headers from the file were modified to make them valid MATLAB identifiers before creating variable names for the table. The original column headers are saved in the VariableDescriptions property.
Set 'VariableNamingRule' to 'preserve' to use the original column headers as table variable names.

X = T.X ;
Y = T.Y ;
Z = T.Z ;
V = T.Dose_nGy_ ;

dt = delaunayTriangulation(X,Y,Z) ;
patch('faces',dt.ConnectivityList,'vertices',[X Y Z],'facevertexcdata',V,'facecolor','interp','edgecolor','k') ;

Also have a look on slice
