Plot date on x axis

Hello, I'm trying to create a plot where the x axis is a range of dates from Sept. 8th to Oct. 25th. I do not have any date matrix already in the code that I'm trying to convert. I was hoping to have the x tick marks as weekly occurances, or Mondays, or whatever works out easiest b/c I feel every day would look to cluttered. The city names are a series of values for each particular day. t is just a series of numbers to plot the data against for now. Thank you in advance.

t=1:1:48;

dateFormat = 19;
datetick('x',dateFormat)

plot(t,Atlanta(:,8))
hold on

xlabel('Date')
ylabel('Percentage')
ylim([80 100])
plot(t,NY(:,4))
plot(t,Chicago)
legend('Atlanta','New York','Chicago')

The datetick call needs to go after the plot call:

t=1:1:48;

plot(t,Atlanta(:,8))
hold on
dateFormat = 19;
datetick('x',dateFormat)
xlabel('Date')
ylabel('Percentage')
ylim([80 100])
plot(t,NY(:,4))
plot(t,Chicago)
legend('Atlanta','New York','Chicago')

Also, datetick requires datenum arguments for the x-axis values, so your current value of ‘t’ will not give recognisable results.
