Plotting x,y,z,p data

To all

I have an input csv file of x,y,z,p data. Where x,y,z are the coordinates of nodes and p is a number (pressure)

I can create a scatter plot of the the x,y,z, see atttached, but cannot create a plot of the value p (as a function of the nodes position). Is there a way of doing this?

Thanks
