I have plotted the 2D histogram between x,y.

Now anyone help me to divide the histogram into four equal quadrants.

You can manualy insert the line as required

data=randi(100,[10,10]);
hist(data);
grid on;
hold on;
x_data=1:100;
y_data=repelem(2,length(x_data));
plot(x_data,y_data,'r','linewidth',2);
