probability- punctual graphs

starting from values of intensity and direction of the wind, I created the graphs relating to the probability of obtaining certain values of intensity and direction of the wind at the same time. I used the bar3 function which creates my instigrams in 3d. is there a function that allows me to calculate the same probability but with a punctual graph? that the numerical values are given back to me.

You can extract the numbers in the bins and divide with total number.
