Trying make a graph with given time data values for all of 2019 managed to plot the graphs but how do i restrict the graph to only plot january using the datetime function?

Alternatively, simply
xlim([datetime(2019,1,1) datetime(2019,1,31)])
will leave all the data plotted but only display that between the two dates selected for the axis limits. This would let you simply reset those to change the visible portion without replotting each time.
Of course, if you want to look at the data and do something else with it (as almost certainly will if not yet), then groupsummary and rowfun will be your very best friends "realsoonnow™"

Alternatively to the above, you might consider using a timetable going forward instead...then retime and friends are also in play...

a = datetime(2021, 1, 1:365);
b = rand(size(a));
plot(a, b)
idx = find(month(a)==1);
xlim([a(idx(1)), a(idx(end))])
