Time vector using stairs

When I use the stairs function with a time vector I get the error message "Input arguments must be numeric.". Is it even possible to use a time vector (YYMMDD) together with the stairs function, and if so, how?

Please post your code, if you want us to understand the source of the problem.

It's not clear what you have and what you're trying to do, but in R2016b and later:

>> strs = {'170101' '170102' '170103' '170104' '170105' '170106' '170107' '170108' '170109' '170110'};
>> d = datetime(strs,'InputFormat','yyMMdd')
d = 
  1×10 datetime array
Columns 1 through 9
   01-Jan-2017   02-Jan-2017   03-Jan-2017   04-Jan-2017   05-Jan-2017   06-Jan-2017   07-Jan-2017   08-Jan-2017   09-Jan-2017
Column 10
   10-Jan-2017
>> stairs(d,1:10)
