The x axis range are [0. , 1.5, 3. , 4.5, 6. ] y axis range are [0. , 0.26875, 0.5375 , 0.80625, 1.075 ] z axis range are [-1.075 , -0.5375, 0. , 0.5375, 1.075 ] The first value i.e. 0.63523489 is the distribution values that exists in x-axis range of 0 to 1.5, y-axis range of 0 to 0.26875 and z-axis range of -1.075 to -0.5375 and so on for other distribution values. So, it's like the three dimensional box with 64 small boxes where each box has given distribution values. As I said, one box has distribution value of 0.63523489.
