How do I plot data date time strings or datetime variables as data points in a plot?

so if I have a vector of datetime variables as the y axis, that have days of the year , and a vector of datetime variables, that have hours in the day, as the xaxis , that represent hours of the day, then a matrix of weather temperatures for my z variable.

How do I plot them all together using the 2-D version of surf, as data points without having to relable the x and y axis?

So if I click on the data cursor in the figure, it will show me the x: hour of the day

y : day of the year dd/mm/yyyy

z : temperature
