Problem plotting time on X axis

I am trying to plot a time series data. I found some examples and tried them but they don't seem to work. I have data as shown:
9:00:38      23.9
9:00:39      23.9

My code looks like this:
[dtmeT, T] = textread (filenameT, "%s %f");  %read in the data
  ser_date=datenum(dtmeT,timeFormat); %serial date is secs since 1/1/0000
  plot(ser_date,T ,'color','k'  );
  xlen = length(dtmeT)  ;
  axis([0 xlen 20 35])

I get a time labeled axis as expected, but I do not see the plot of T. The data is valid-if I plot it without time formatting it works fine.
