matlab将毫秒转换为日期格式并绘制为x轴

Question

I am new to matlab. What I am trying to do is to plot the data I recorded from the phone on matlab. The data is looks like this {timestamp, value}.

The timestamp is recorded in millionseconds by calling the Java function System.currentTimeMillis(). Therefore I have two questions actually to plot it on matlab.

1. How can I transform the timestamp from milliseconds to date format on matlab?

2. How can I plot the data on matlab, where Y-axis is the value, and X-axis is the date? The graph should look like discrete dots.

Thanks a lot.

Answer 1

To create plots with dates / times on one axis, plot your data, then relabel the axis using datetick

plot(datenum('1-jan-2000'):datenum('10-jan-2000'),[1:10])
datetick('x','dd-mm')
