Plot date labels in x-axis

I have a plot with dates in form of mm/dd as x-axis data. Now I have

xData = ["01/22"    "01/23"    "01/24"    "01/25"    "01/26"    "01/27"    "01/28"    "01/29"]

which is a string array of size 1 x 8.

How do I plot with

yData = [557         655         941        1433        2118        2927        5578        6167]

by using something like

plot(xData, yData)

with ["01/22" "01/23" "01/24" "01/25" "01/26" "01/27" "01/28" "01/29"] as the x-axis tick labels?

Currently I got the error messages "Error using plot.

Not enough input arguments." when running plot(xData, yData) as above, which I don't know what it exactly means.

xData = ["01/22"    "01/23"    "01/24"    "01/25"    "01/26"    "01/27"    "01/28"    "01/29"]

xData = 1×8 string array
    "01/22"    "01/23"    "01/24"    "01/25"    "01/26"    "01/27"    "01/28"    "01/29"

yData = [557         655         941        1433        2118        2927        5578        6167]

yData = 1×8

557 655 941 1433 2118 2927 5578 6167

x = datetime(xData, 'inputFormat', 'MM/dd', 'Format', 'MM/dd')

x = 1×8 datetime array
   01/22   01/23   01/24   01/25   01/26   01/27   01/28   01/29

plot(x, yData)

xData = ["01/22"    "01/23"    "01/24"    "01/25"    "01/26"    "01/27"    "01/28"    "01/29"]

xData = 1×8 string array
    "01/22"    "01/23"    "01/24"    "01/25"    "01/26"    "01/27"    "01/28"    "01/29"

yData = [557         655         941        1433        2118        2927        5578        6167]

yData = 1×8

557 655 941 1433 2118 2927 5578 6167

% Convert the string to datetime
x = datetime(xData, 'InputFormat', 'MM/dd')

x = 1×8 datetime array
   22-Jan-2021   23-Jan-2021   24-Jan-2021   25-Jan-2021   26-Jan-2021   27-Jan-2021   28-Jan-2021   29-Jan-2021

plot(x, yData)
datetick('x', 'mm/dd')      % note the different case for month
