How can I use datetick with more than x, y, z in input and on Y-axis?

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.

Thanks a lot, I didn't understand it in that way.
