How to correct 'xtick' label format in plot of a 'timeseries' object?

The following code creates a plot of "timeseries" object. But the 'xtick' labels are not formatted correctly. 

a=rand(1,N);
ym=[[repmat(2000,12,1) (1:12)'];[repmat(2001,12,1) (1:12)']];
disp(ym);
datevec = datenum(ym(:,1),ym(:,2),1);
ts1=timeseries(a, datevec);
ts1.TimeInfo.Format = 'mmm-yyyy';
plot(ts1);

I want them to be labeled in 'mmm-yyyy' format.

According to the documentation of 'timeseries' object, the 'timevals' should be in 'datestr' format. Use 'datestr' function to utilize the time vector in required format.

The following code produces the desired plot: 

a=rand(1,N);
ym=[[repmat(2000,12,1) (1:12)'];[repmat(2001,12,1) (1:12)']];
disp(ym);
datevec = datenum(ym(:,1),ym(:,2),1);
datevec = datestr(datevec);
ts1=timeseries(a, datevec);
ts1.TimeInfo.Format = 'mmm-yyyy';
plot(ts1);

Please run the below command in the command window of installed MATLAB R2019a version to get release specific documentation to read more about the "timeseries" object:

Please run the below command in the command window of installed MATLAB R2019a version to get release specific documentation on "satestr" function:
