you can take any value of density just i wanna know to how to creat histogram of density

Each plot has different customization options.

Try creating a histogram of density with the histogram function.

Set the "FaceColor" to yellow ("y").

[DGM]

density = randn(100);
h = histogram(density);
h.FaceColor = 'y'; 

% if you want to set other properties, take a look
get(h)

% properties can be read/set using get/set
get(h,'FaceColor')

ans = 1×3

1 1 0

set(h,'FaceColor','b')
% or by using dot notation as in the initial example
