Inserting date and time variables into graphs title

I have the following code:

startDate=datetime('03-Oct-2014','InputFormat','dd-MMM-yyyy');
endDate=datetime('15-Oct-2014','InputFormat','dd-MMM-yyyy');
start_end_time = endDate-startDate;
start_end_time_days = days(start_end_time);

When I try to set title on the plot like this:

Ticker = 'SPY';
title([Ticker, ' Bought in ', char(start_end_time_days), ' days before some event']);

I get an empty string: SPY Bought in days before some event

I experimented with the code removing char() and doing like:

title([Ticker, ' Bought in ', start_end_time_days, ' days before some event']);

though it didn't help either.

I do not find the command days in the documentation. What kind of variable does it reply? Please post the type and the value.

>> start_end_time_days = days(start_end_time)

start_end_time_days =

      12

BTW, where's the yesterdays comment, Jan? It helped )

Answer 1

[Jan]

Pure guessing:

If days replies the number of days as a double value:

Ticker = 'SPY';
title([Ticker, ' Bought in ', sprintf('%f', start_end_time_days), ...
       ' days before some event']);

Or shorter (and perhaps with %d instead of %f):

title(sprintf('%s Bought in %d days before some event', ...
              Ticker, start_end_time_days));

That's solved the issue. Thanks ) I used the second one.
