fid = fopen('B0B1_Daytime.txt');
datacell =textscan(fid,'%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f%f', 'collectoutput', true);
M=datacell{1,1};
x = (M(:,2));
y = (M(:,1));
z = (M(:,9));
scatter(x,y,2,z,'s','filled')
This is the code that i have written here for the plot of x,y and z as surface plot. as it is attached here.
I want this plot with binned value and each bin should has median values in a bin.

You can try gridbin.

I haven't used it myself, but it seems to do what you need.

The documentation states you can supply any function to be applied to each grid cell, so providing @median should work.
