Visualize pressure on a cylinder surface

I have text file (Pressure.txt) with the cylinder's coordinate (x,y,z) in the first three columns and pressure values for each point in the fourth column (don't consider the fifth column of the file). How could I visulize the pressure distributiion on the external surface of the cylinder?

Thank you

Attach your file.....visulazation depends on how is your data...structured or unstructured.....so it is better to attach the data for straight help.

I attached the file Pressure.txt (don't consider the fifth column). Thank

Assuming your data are stored in a matrix named 'data',

X = reshape(data(:,1), length(unique(data(:,1))), []); 
Y = reshape(data(:,2), length(unique(data(:,1))), []);  
Z = reshape(data(:,3), length(unique(data(:,1))), []); 
C = reshape(data(:,4), length(unique(data(:,1))), []); 

surf(X,Y,Z,C)
axis equal
ch = colorbar; 
ylabel(ch, 'Pressure') %not shown in image
