Plot x 轴上的日期标签 [MATLAB]

Question

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.

Answer 1

I can think of two possibilities:

1. Convert the xData into a datetime array and use it in the plot

   plot(datetime(xData, 'InputFormat', 'MM/dd', 'Format', 'MM/dd'), yData)

2. Use xData as the label of the x axis:

    plot(yData) set(gca, 'XTick', 1:length(yData), 'XTickLabel', xData)

Answer 2

plot(datetime(xData, 'InputFormat', 'MM/dd', 'Format', 'MM/dd'), yData)
