Matlab Plot; one data set, two axis, date

I am trying to plot a single data set in terms of dates (x axis), I would like to add on the second (top) x axis with interval of time in days. Any suggestion?

One way is to create another axes on top of the first, and put the xaxis location at the 'top' for that. Here is a small example.

% Some example data
d = linspace(now,now-7,7);
y = randn(size(d));

% Create first axes
ax1 = axes;
plot(d,y);
datetick(ax1, 'x', 'yy-mm-dd')

% Create second axes
ax2 = axes;
plot(d,y,'Visible', 'off'); % No need to show doubles
set(ax2, 'Position', ax1.Position, 'XAxisLocation', 'top', ...
    'Color', 'none' ,'YTick', []);
datetick(ax2, 'x', 'ddd')
