Can't add more x-axis ticks or number of x-axis elements displayed.

TimeCol=datenum(Sheet.Time);

TimeCol=Sheet1.Time/(24*3600);

TimeCol=datevec(TimeCol);

TimeCol=datetime(TimeCol);

plot(TimeCol,Value)

This results in an x-axis from 07:00 to 09:00 (hh:mm) in increments of 00:30, and I can't find a way to either add ticks every 15 minutes nor change the number of times displayed.

First, I'll try to reproduce something like your plot:

TimeCol=datetime(datevec(now()+seconds(1800*(0:4))));
Value = rand(1,5);

figure
plot(TimeCol,Value)

Now, I'll plot the same thing, but I'll adjust the x-ticks by setting the increment to 15 minutes:

figure
plot(TimeCol,Value)

xt = xticks();
xt = xt(1):duration(minutes(15)):xt(end);
xticks(xt);

Another identical plot, but this time specify that there must be 10 x-ticks:

figure
plot(TimeCol,Value)

xt = xticks();
xt = linspace(xt(1),xt(end),10);
xticks(xt);
