MATLAB: How to use datetick with more than x, y, z in input and on Y-axis

datenumdatetickplot y-axisserial number

Hello,
I am using datenum to convert time txt in MM:SS.FFF in serial date number. The next step is to change those numbers in MM:SS.FFF with datetick when I am ploting.
My problem is that I have more than just 3 inputs (in datetick there is just 'x','y','z' in possibilities)to put in my plot and I would like to have the time Format in Y-axis.
I have :
Format = 'MM:SS.FFF';
x= datenum(txt,Format);
x1= datenum(txt2,Format); 
x2= datenum(txt3,Format);
x3= datenum(txt4,Format);
x4= datenum(txt5,Format);
plot(y,x,y,x1,y,x2,y,x3,y,x4)
datetick('x',Format,'keepticks');
datetick('x1',Format,'keepticks');
datetick('x2',Format,'keepticks');
datetick('x3',Format,'keepticks');
datetick('x4',Format,'keepticks');
So I have 2 errors in this case: x1, x2, x3, x4 are not considering in input argument and x should be in X-axis.
How can I do it with datetick or with something else from my serial numbers from datenum ?
Thank you
Martin

Syntax for datetick is
 datetick(tickaxis)
not
datetick(wanteddateaxisvariablename)
Just need
datetick('y',Format,'keepticks')
However, I'd strongly suggest unless you're running a version of Matlab prior to R2014b to convert from datenum to the datetime class. plot and friends have subsequently been made datetime aware so don't need klunky datetick any longer.
