I'm just trying to understand plotting prices as a function of time, if I have price data of prices in a column, say x=[1;2;3;4;5;6;7;8;9;13;14;15] and creating a time axis of integers from 1 to the number of days so 1:length of the first colum am I correcting in the definition of plotting the prices as a function of time by.
numberofdays=size(x,1)
plot(1:numberdays,x(:,1)) %equivalent to plot(t,y) where x(:,1) are the first column price values

For the given description, yes. BUT, you should probably create your date vector as one of the datetime or duration class instead as just integers if there is anything excepting just arbitrary day sequence number in the time series. Most often, one only has economic data that is associated with an actual date.
