how do I match the datetick?

Hi all,

I've attached the plot that I want to correct the datetick (it doesn't match with the real date). Could anyone help, please?

thanks in advance.

The x axes ranges from 0 to 800. What should the corresponding date and times be for 0 and 800, and which dates/times do you want marked on the axis?

it should be hours 744hr/1 month (Aug or july =31 days)

h = openfig('AugWnd.fig');
ax = get(h,'CurrentAxes');
ax.XAxis.TickLabels = cellstr(datestr(ax.XAxis.TickValues/24 + datenum('2017-08-01'),'dd-mmm'));

Note that the ticks are 100 hours apart. You might want to consider changing ax.XAxis.TickValues to [0:96:799, 800] to get every 4 days plus the end point.
