'20-Jan-2006 06:17:00'

I wand to display it on the x-axis of a candle chart with the function datetick('x',t). However, I get the following error message

Error using message In 'MATLAB:datetick:UnknownDateFormat', data type supplied is incorrect for parameter {1}.

Error in datetick (line 154) error(message('MATLAB:datetick:UnknownDateFormat', dateform));

>> How do I resolve this?

The second input argument of datetick is supposed to be the date format. (It looks like you entered the variable name.)

Here is a working example with your data:
