MATLAB: How to select particular timeperiod in timestamp for plotting

Question

I have timeperiod from:

startDate = datetime(2020, 3, 22, 23, 0, 0); %initial start date

stopDate = datetime(2020, 3, 31, 03, 0, 0); %stop date

Invdata = databaseconnection(startDate, stopDate); %accessing data from database for that time period and storing in Invdata matrix

So initially, my datapoints length was 70553. I did some data filtering, and now the length is 2351. I want to plot a graph like :

plot(timestamp, datas). But my timestamp length doesnt match with data length. What should I do?

Error message: 'Vectors must be the same length'.

Answer 1

linspace supports datetime() values

startDate = datetime(2020, 3, 22, 23, 0, 0);  %initial start date
stopDate = datetime(2020, 3, 31, 03, 0, 0);    %stop date
timestamp = linspace(startDate, stopDate, 2351);
